==Historical development==
The procedures for the election of the pope developed over almost two [[millennium|millennia]]. Until the College of Cardinals was created in 1059, the bishops of Rome, like those in other areas, were elected by acclamation of the local clergy and people. Procedures similar to the present system were introduced in 1274 when [[Gregory X]] promulgated ''[[Ubi periculum]]'' following the action of the magistrates of [[Viterbo]] during the interregnum of 1268–1271.<ref name="CE-Conclave">{{CathEncy | author= Dowling, A. | wstitle= Conclave}}</ref>

The process was further refined by [[Gregory XV]] with his 1621 [[papal bull]] ''[[Aeterni Patris Filius]]'', which established the requirement of a two-thirds majority of cardinal electors to elect a pope.<ref>Signorotto and Visceglia 2002, p. 106</ref> The [[Third Council of the Lateran]] had initially set the requirement that two-thirds of the cardinals were needed to elect a pope in 1179.<ref name=Baumgartner3233>Baumgartner 2003, pp. 32–33</ref> This requirement had varied since then, depending on whether the winning candidate was allowed to vote for himself, in which cases the required majority was two-thirds plus one vote. ''[[Aeterni Patris Filius]]'' prohibited this practice and established two-thirds as the standard needed for election.<ref name=Baumgartner146>Baumgartner 2003, p. 146</ref>

''Aeterni Patris Filius'' did not eliminate the possibility of [[election by acclamation]], but did require that a secret ballot take place first before a pope could be elected.<ref>Baumgartner 2003, p. 145</ref> Prior to 1621, a cardinal could vote for himself, but it was always with the knowledge and consent of enough of the other voting cardinals, so that he did not make the final decision to make himself pope ([[accessus]]). Ballots were either signed or initialed in the corner of the ballot, or sometimes coded and numbered.<ref name=VacanteAS64>Vacante A S, 1904</ref>
===Electorate===
{{Main|Papal selection before 1059}}

As [[Early Christianity|early Christian]] communities emerged, they elected bishops, chosen by the clergy and [[laity]] with the assistance of the bishops of neighbouring dioceses.<ref name="Baumgartner4" /> [[Cyprian]] (died 258) says that [[Pope Cornelius]] (in office 251–253) was chosen as bishop of Rome "by the decree of God and of His Church, by the testimony of nearly all the clergy, by the college of aged bishops [''sacerdotum''], and of good men".<ref name="CE-Election">{{CathEncy | author= Joyce, G. H. | wstitle= Election of the Popes}}</ref> As in other dioceses, the clergy of the [[Diocese of Rome]] was the electoral body for the bishop of Rome. Instead of casting votes, the bishop was selected by general [[Consensus decision-making|consensus]] or by [[acclamation]]. The candidate was then submitted to the people for their general approval or disapproval. This lack of precision in the election procedures occasionally gave rise to rival popes or [[antipope]]s.<ref name="CE-Papal">{{CathEncy | author= Fanning, W. H. W. | wstitle= Papal Elections}}</ref>

The right of the laity to reject the person elected was abolished by a [[Lateran Council (769)|synod held in the Lateran]] in 769, but restored to [[Patrician (post-Roman Europe)|Roman noblemen]] by [[Pope Nicholas I]] during a synod of Rome in 862.<ref name="CE-Papal" /> The pope was also subjected to oaths of loyalty to the [[Holy Roman emperor]], who had the duty of providing security and public peace in Rome.<ref>Baumgartner 2003, p. 14–19.</ref> A major change came in 1059, when [[Pope Nicholas II]] decreed in {{lang|la|[[In nomine Domini]]}} that the cardinals were to elect a candidate to take office after receiving the assent of the clergy and laity. The [[cardinal bishop]]s were to meet first and discuss the candidates before summoning the [[cardinal priest]]s and [[cardinal deacon]]s for the actual vote.<ref name="CE-Election" /> The [[Second Council of the Lateran]] in 1139 removed the requirement for obtaining the assent of the lower clergy and the laity,<ref name="CE-Papal" /> while the [[Third Council of the Lateran]] in 1179 gave equal rights to the entire College of Cardinals when electing a new pope.<ref name="Guruge49">Guruge 2010, p. 49.</ref>

Through much of the [[Middle Ages]] and [[Renaissance]] the Catholic Church had only a small number of cardinals at any one time, as few as seven under either [[Pope Alexander IV]] (1254–1261)<ref name="CE-Cardinal">{{CathEncy | author=Sägmüller, Johannes Baptist | wstitle=Cardinal}}</ref> or [[Pope John XXI]] (1276–1277).<ref name="Miranda-xiii">Miranda, Salvador.

The small electorate magnified the significance of each vote and made it all but impossible to displace familial or political allegiances. Conclaves lasted months and even years. In his 1274 decree requiring the electors be locked in seclusion, Gregory X also limited each cardinal elector to two servants and rationed their food progressively when a conclave reached its fourth and ninth days.<ref name="CE-Papal" />

The cardinals disliked these rules; [[Pope Adrian V]] temporarily suspended them in 1276 and John XXI's ''[[Licet felicis recordationis]]'' revoked them later that same year.<ref name="CE-JohnXXI">{{CathEncy | author= Kirsch, Johann Peter | wstitle= Pope John XXI (XX)}}</ref>{{efn|Each of these popes intended to promulgate a new constitution governing papal elections but died before doing so.}} Lengthy elections resumed and continued to be the norm until 1294, when [[Pope Celestine V]] reinstated the 1274 rules.<ref>Baumgartner 2003, p. 44–46.</ref> Long interregna followed: in [[Papal conclave, 1314–1316|1314–1316]] during the [[Avignon Papacy]], where the original conclaves were dispersed by besieging mercenaries and not reconvened for almost two years;<ref>Levillain 2002, p. 848.</ref> and in 1415–1417, as a result of the [[Western Schism]].

Until 1899, it was a regular practice to generally include a few lay members in the [[College of Cardinals|Sacred College]]. These were often prominent nobility, or monks who were not priests, and in all cases, celibacy was required. With the death of [[Teodolfo Mertel]] in 1899, this practice was ended.<ref>"https://cardinals.fiu.edu/cardinals.htm</ref> In 1917, the [[1917 Code of Canon Law|Code of Canon Law]] promulgated that year, explicitly stated that all cardinals must be priests. Since 1962, all cardinals have been bishops, with the exception of a few priests who have been made cardinals since about 1970. These few have all been at least 80 years old and not allowed to vote in a papal election, since Paul VI in that same year of 1970 imposed the rule that all voting cardinals be under 80 years of age.  If a priest is asked by the pope to become a cardinal he may request not to be ordained a bishop, but this is the exception rather than the rule.   

In 1587, [[Pope Sixtus V]] limited the number of cardinals to 70, following the precedent of [[Moses]] who was assisted by 70 elders in governing the [[Children of Israel]]: 6 cardinal bishops, 50 cardinal priests, and 14 cardinal deacons.<ref name="CE-Cardinal" /> Beginning with the attempts of [[Pope John XXIII]] (1958–1963) to broaden the representation of nations in the College of Cardinals, that number has increased. In 1970 [[Pope Paul VI|Paul VI]] ruled that cardinals who reach the age of 80 before the start of a conclave are ineligible to participate.<ref>{{cite web |author=Pope Paul VI |date=20 November 1970 |url= https://www.vatican.va/holy_father/paul_vi/motu_proprio/documents/hf_p-vi_motu-proprio_19701120_ingravescentem_lt.html |title=Ingravescentem aetatem |language=la |website=Vatican | access-date=4 December 2017}}</ref>

In 1975, he limited the number of cardinal electors to 120.<ref name="RPE">{{cite web | author=Pope Paul VI |date=1 October 1975 |url=https://www.vatican.va/holy_father/paul_vi/apost_constitutions/documents/hf_p-vi_apc_19751001_romano-pontifici-eligendo_lt.html |title=Romano Pontifici eligendo | language=la |website=Vatican |access-date=4 December 2017}}</ref> Though this remains the theoretical limit, all of his successors have exceeded it for short periods of time. [[Pope John Paul II|John Paul II]] (in office 1978–2005) made a slight change to the age limit rules, barring cardinals 80 or older from serving as electors if they reach that age before the papacy becomes vacant.<ref name="UDG" /> This change eliminated the possibility of scheduling a conclave to include or exclude a cardinal who might be close to the limit. The [[2025 papal conclave]] was the first time that more than 120 cardinal-electors participated, at 133.

===Choice of electors and of candidates===
Originally, lay status did not bar election to the See of Rome. Bishops of dioceses were sometimes elected while still [[catechumen]]s, such as the case of [[St. Ambrose]],<ref>{{CathEncy | author=Loughlin, James Francis | wstitle=St. Ambrose}}</ref> who became bishop of Milan in 374. In the wake of the violent dispute over the 767 election of [[Antipope Constantine II]], [[Pope Stephen III]] held the synod of 769, which decreed that only a cardinal priest or cardinal deacon could be elected, specifically excluding those that are already bishops.<ref name="CE-Election" /><ref>Baumgartner 2003, p. 13.</ref> Church practice deviated from this rule as early as 817 and fully ignored it from 882 with the election of [[Pope Marinus I]], the [[bishop of Caere]].<ref>Guruge 2010, p. 46–47.</ref>

Nicholas II, in the synod of 1059, formally codified existing practice by decreeing that preference was to be given to the clergy of Rome, but leaving the cardinal bishops free to select a cleric from elsewhere if they so decided.<ref name="Baumgartner21">Baumgartner 2003, p. 21-23.</ref> The [[Third Council of the Lateran|Council of 1179]] rescinded these restrictions on eligibility.<ref name="Guruge49" /> On 15 February 1559, [[Paul IV]] issued the papal bull ''[[Cum ex apostolatus officio]]'', a codification of the ancient Catholic law that only Catholics can be elected popes, to the exclusion of non-Catholics, including former Catholics who have become public and manifest heretics.

During the first millennium, popes were elected unanimously, at least in theory. After a decree by the Synod of Rome in 1059, some factions contended that a simple majority sufficed to elect. In 1179, the [[Third Council of the Lateran]] settled the question by calling for unanimity, but permitting the Pope to be elected by two-thirds majority, "if by chance, through some enemy sowing tares, there cannot be full agreement."<ref name=Baumgartner3233/><ref>{{Cite web |title=Canon 1 |url=https://www.papalencyclicals.net/councils/ecum11.htm |url-status=live |archive-url=https://web.archive.org/web/20071012074921/https://www.papalencyclicals.net/councils/ecum11.htm |archive-date=12 October 2007 |access-date=21 March 2024 |website=Papal Encyclicals Online |date=5 March 1179 |publisher=[[Third Council of the Lateran]]}}</ref> As cardinals were not allowed to vote for themselves after 1621, the ballots were designed to ensure secrecy while at the same time preventing self-voting.{{efn|The ''London Magazine'' printed an image of a ballot design in 1903 with this description: "It is divided into three compartments, in the first of which the Cardinal writes his own name, in the second that of the candidate for whom he votes, and in the third a motto and number.

In 2007, [[Pope Benedict XVI|Benedict XVI]] rescinded John Paul II's change, which had effectively abolished the two-thirds majority requirement, as any majority suffices to block the election until a simple majority is enough to elect the next pope, reaffirming the requirement of a two-thirds majority.<ref name="BXVI-MP"/><ref name="BBC-BXVI"/>

Electors formerly made choices by [[accessus]], [[Acclamation (Papal elections)|acclamation]] (''per inspirationem''), adoration, compromise (''per compromissum''), or scrutiny (''per scrutinium'').<ref name="CE-Conclave" />
* '''Accessus''' was a method for cardinals to change their most recent vote to accede to another candidate in an attempt to reach the requisite two-thirds majority and end the conclave. This method was first disallowed by the [[cardinal dean]] at the [[1903 papal conclave|1903 conclave]].<ref name="CE-Conclave" /> Pius XII abolished accessus in 1945.
* With '''acclamation''', the cardinals unanimously declared the new pope ''quasi afflati Spiritu Sancto'' (as if inspired by the [[Holy Spirit]]).<ref name="VAS" /> If this took place before any formal ballot had taken place, the method was called '''adoration''',<ref>Baumgartner 2003, Glossary.</ref> but [[Pope Gregory XV]] excluded this method in 1621.<ref>{{CathEncy | author=Ludovisi, Alessandro | wstitle= Pope Gregory XV}}</ref><ref>Gregory XV (15 November 1621).

===Secular influence===
For a significant part of the Church's history, powerful monarchs and governments influenced the choice of its leaders. For example, the [[Roman emperors]] once held considerable sway in the elections of popes. In 418, Emperor [[Flavius Augustus Honorius|Honorius]] settled a controversial election, upholding [[Pope Boniface I]] over the challenger [[Antipope Eulalius]]. On the request of Boniface I, Honorius ordered that in future cases, any disputed election would be settled by a fresh election.<ref>{{CathEncy | wstitle= Pope St. Boniface I | author= Peterson, John B.}}</ref>

After the demise of the [[Western Roman Empire]], influence passed to the [[Ostrogoth]]ic [[kings of Italy]]. In 533, [[Pope John II]] formally recognised the right of the Ostrogothic monarchs to ratify elections. By 537, the Ostrogothic monarchy had been overthrown, and power passed to the [[Byzantine emperors]]. A procedure was adopted whereby officials were required to notify the [[exarch of Ravenna]] upon the death of a pope before proceeding with the election.<ref>Baumgartner 2003, p. 10.</ref> Once the electors arrived at a choice, they were required to send a delegation to [[Constantinople]] requesting the emperor's consent, which was necessary before the individual elected could take office.<ref name="auto">Duffy 2006, p. 73.</ref>

Travel to and from Constantinople caused lengthy delays.<ref name="auto"/> When [[Pope Benedict II]] (684–685) complained about them, Emperor [[Constantine IV]] (in office 654–685) acquiesced, ending the requirement for emperors to confirm elections. Thereafter, the emperor was only required to be notified.<ref>{{CathEncy | wstitle= Pope St. Benedict II | author= Mann, Horace K.}}</ref> The last pope to notify a Byzantine emperor was [[Pope Zachary|Zachary]] in 741.<ref>Baumgartner 2003, p. 12.</ref>

In the 9th century, the [[Carolingian Empire]] (and its successor, the [[Holy Roman Empire]]) came to exert control over papal elections.

In 1059, the same papal bull that restricted suffrage to the cardinals recognised the authority of the Holy Roman emperor, at the time [[Henry IV, Holy Roman Emperor|Henry IV]], but only as a concession made by the pope, declaring that the emperor had no authority to intervene in elections, except where permitted to do so by papal agreements.<ref name="Baumgartner21" /> [[Pope Gregory VII]], in office 1073–1085, was the last pope to submit to the interference of the Holy Roman emperors.

From about 1600, certain Catholic monarchs claimed a ''[[jus exclusivae]]'' (right of exclusion), i.e. a veto over papal elections, exercised through a [[crown-cardinal]]. By an informal convention, each state claiming the veto could exercise the right, once per conclave. Therefore, a crown-cardinal did not announce his veto until the very last moment, when the candidate in question seemed likely to get elected. No vetoes could be employed after an election. After the Holy Roman Empire dissolved in 1806, its veto power devolved upon the [[Austrian Empire]]. The last exercise of the veto occurred in 1903, when Prince [[Jan Puzyna de Kosielsko]] informed the College of Cardinals that Austria opposed the election of [[Mariano Rampolla]]. Consequently, the college elected Giuseppe Sarto as [[Pope Pius X]], who issued the [[Apostolic constitution|constitution]] ''[[Commissum nobis]]'' six months later, declaring that any cardinal who communicated his government's veto in the future would suffer [[excommunication]] ''[[latae sententiae]]''.<ref>{{CathEncy | wstitle=Right of Exclusion | author=Sägmüller, Johannes Baptist}}</ref><ref>{{cite EB1911|wstitle= Conclave|volume=6 |page=829 |first=Auguste |last=Boudinhon}}</ref>

===Seclusion and resolution===
To resolve prolonged deadlocks in papal elections in the earlier years, local authorities often resorted to the forced seclusion of the cardinal electors, such as first in the city of [[Rome]] in [[1241 papal election|1241]], and possibly before that in [[Perugia]] in [[1216 papal election|1216]].<ref>Guruge 2010, p. 141.</ref> In [[1268–1271 papal election|1268]], when the forced seclusion of the cardinals failed to produce a pope, the city of Viterbo refused to send in any materials except bread and water. When even this failed to produce a result, the townspeople removed the roof of the [[Palazzo dei Papi di Viterbo|Palazzo dei Papi]] in their attempt to speed up the election. It lasted for two years and eight months and was the longest conclave in history.<ref>Wright, David (18 April 2005). [https://abcnews.go.com/WNT/Pope/story?id=681429 "Inside Longest Papal Conclave in History"] {{Webarchive|url=https://web.archive.org/web/20180320091402/https://abcnews.go.com/WNT/Pope/story?id=681429 |date=20 March 2018 }}. Viterbo: ''[[ABC News (United States)|ABC News]]''.</ref>

In 1274, in an attempt to avoid future lengthy elections, Gregory X introduced stringent rules, with the promulgation of ''[[Ubi periculum]]''. Cardinals were to be secluded in a closed area and not accorded individual rooms. No cardinal was allowed, unless ill, to be attended by more than two servants. Food was supplied through a window to avoid outside contact.{{efn|Formerly, cardinals regularly had meals sent in from their homes with much pageantry accompanying the conveyance of food: "Towards noon each day, the Cardinal's gentlemen proceeded to his house and conveyed his dinner to the Vatican in a state coach. They were accompanied by an officer, known as the Seneschal Dapifer, who was charged with the very important duty of seeing that the Cardinal's food was not poisoned! ... The dishes were enclosed in hampers or tin boxes, covered with green or violet drapery, and ... were carried in state through the entrance halls, preceded by the [[Ceremonial mace|mace]] of the cardinal. The Seneschal Dapifer, bearing a serviette on his shoulder, preceded the dishes.... Before the Cardinal received his dinner, each dish underwent a careful inspection by the prelates on guard, in order that no letter should be concealed in it."<ref name=wintle/> These ceremonies have not been observed since the nineteenth century.}} After three days of the conclave, the cardinals were to receive only one dish a day. After another five days, they were to receive just bread and water. During the conclave, no cardinal was to receive any ecclesiastical revenue.<ref name="CE-Papal" /><ref>Goda, Paul (15 April 2005).

In 1276, [[Pope Adrian V|Adrian V]] abolished Gregory X's strict regulations. [[Pope Celestine V|Celestine V]], elected in 1294 following a two-year vacancy, restored them. In 1562, [[Pope Pius IV|Pius IV]] issued a papal bull that introduced regulations relating to the enclosure of the conclave and other procedures. Gregory XV issued two bulls that covered the most minute of details relating to the election. The first, in 1621, concerned electoral processes. The other, in 1622, fixed the ceremonies to be observed. In December 1904, [[Pope Pius X]] issued an apostolic constitution consolidating almost all the previous rules, albeit with some changes, the ''Vacante sede apostolica''.<ref>{{ Cite journal| access-date = 3 November 2017 | url = https://books.google.com/books?id=sE34bUAn1aMC&pg=PA426 | journal=The Ecclesiastical Review |page=426 |title= The Roman Curia | volume = 43 |first= M. | last= Martin S.J. | date=1910 }}</ref> John Paul II instituted several reforms in 1996.<ref name="CE-Conclave" />

The location of the conclaves became fixed in the fourteenth century. Since the end of the [[Western Schism]] in 1417, they have taken place in Rome, except in 1799–1800, when French troops occupying Rome forced the election to be held in [[Venice]], and normally in what, since the [[Lateran Treaties]] of 1929, has become the independent [[Vatican City]] State. Since 1846, when the [[Quirinal Palace]] was used, the [[Sistine Chapel]] in the Vatican has served as the location of the election. Popes have often fine-tuned the rules for the election of their successors: [[Pope Pius XII]]'s ''Vacantis Apostolicae Sedis'' (1945) governed the conclave of 1958, [[Pope John XXIII]]'s ''Summi Pontificis electio'' (1962) that of 1963, [[Pope Paul VI]]'s ''[[Romano Pontifici eligendo]]'' (1975) the two conclaves of 1978, [[Pope John Paul II]]'s ''[[Universi Dominici gregis]]'' (1996) that of 2005, and [[Papal election reforms of Pope Benedict XVI|two amendments by Pope Benedict XVI]] (2007 and 2013) that of 2013 and 2025.

==Modern practice==
{{Main|Universi Dominici gregis}}
[[File:Domus Sanctae Marthae from the Dome of St. Peter's.jpg|thumb|Since the [[2005 papal conclave]], the cardinal electors reside in the [[Domus Sanctae Marthae]] for the length of the conclave.]]
In 1996, John Paul II promulgated a new [[apostolic constitution]], ''[[Universi Dominici gregis]]'', which with [[Papal election reforms of Pope Benedict XVI|slight modifications]] by [[Pope Benedict XVI]] now governs the election of the pope, abolishing all previous constitutions on the matter, but preserving many procedures that date to much earlier times. Under ''Universi Dominici gregis'', the cardinals are to be lodged in a purpose-built edifice in Vatican City, the [[Domus Sanctae Marthae]], but continue to vote in the Sistine Chapel.<ref>{{cite web|url=http://www.ewtn.com/HolySee/Interregnum/domus.asp|title=Interesting Conclave Facts|work=ewtn.com|access-date=7 September 2006|archive-date=12 July 2018|archive-url=https://web.archive.org/web/20180712081751/http://www.ewtn.com/HolySee/Interregnum/domus.asp}}</ref>

Several duties are performed by the [[dean of the College of Cardinals]], who is always a cardinal bishop. If the dean is not entitled to participate in the conclave owing to age, his place is taken by the vice-dean, who is also always a cardinal bishop. If the vice-dean cannot participate, the senior cardinal bishop participating performs the functions.<ref>{{cite web|url=http://www.cwnews.com/news/viewstory.cfm?recnum=36884 |title=Cardinal Sodano elected dean of College of Cardinals |publisher=Cwnews.com |date=2 May 2005 |access-date=12 March 2013}}</ref>

Since the College of Cardinals is a small body, there have been proposals that the electorate should be expanded. Proposed reforms include a plan to replace the College of Cardinals as the electoral body with the [[Synod of Bishops in the Catholic Church|Synod of Bishops]], which includes many more members. Under present procedure, the synod may only meet when called by the pope. ''Universi Dominici gregis'' explicitly provides that even if a synod or an [[ecumenical council]] is in session at the time of a pope's death, it may not conduct the election. Upon the pope's death, both bodies' proceedings are suspended, to be resumed only upon the order of the new pope.<ref>Some have proposed the election of the pope by a special synod of bishops. This would imitate some of the Eastern-rite churches where metropolitans and patriarchs are elected by synods of bishops. The method for selecting the synod members would remain controversial.[http://www.americamagazine.org/reese/america/a-papel1.htm Cardinals and Conclaves] {{webarchive|url=https://web.archive.org/web/20060823142431/http://www.americamagazine.org/reese/america/a-papel1.htm |date=23 August 2006 }}, By Thomas J.

===Death of a pope===
[[File:Cardinal Camerlengo certifying a papal death.JPG|thumb|upright|The [[Camerlengo of the Holy Roman Church|camerlengo]] proclaiming a papal death]]
[[File:John Paul II funeral long shot.jpg|thumb|Cardinals, bishops and priests attending the [[funeral of Pope John Paul II]]]]
The death of the pope is verified by the [[Camerlengo of the Holy Roman Church|cardinal camerlengo]], or chamberlain, who traditionally performed the task by calling out his baptismal (not papal) name. After confirming the death of the pope, the camerlengo pronounces the phrase "''[[sede vacante]]''" ("The throne is empty"). The camerlengo takes possession of the [[Ring of the Fisherman]] worn by the pope. The ring, along with the papal seal, is later destroyed before the College of Cardinals. The tradition originated to avoid forgery of documents, but today merely is a symbol of the end of the pope's reign.<ref>{{cite web|url=http://www.cwnews.com/news/viewstory.cfm?recnum=36299 |title=Toward the conclave #1: the office of camerlengo |publisher=Cwnews.com |date=5 April 2005 |access-date=12 March 2013}}</ref><ref>Menachery George "Last Days of Pope John Paul II"http://www.indianchristianity.com/html/Books.html {{Webarchive|url=https://web.archive.org/web/20151028145915/http://www.indianchristianity.com/html/Books.html |date=28 October 2015 }}</ref>

During the ''sede vacante'', as the papal vacancy is known, certain limited powers pass to the College of Cardinals, which is convoked by the dean of the College of Cardinals. All cardinals are obliged to attend the general congregation of cardinals, except those whose health does not permit, or who are over eighty. Those older cardinals may choose to attend if they please as non-voting members.<ref name=":6">[http://www.aquinas-multimedia.com/cards/sedeva.html Sede Vacante] {{Webarchive|url=https://web.archive.org/web/20060825032333/http://www.aquinas-multimedia.com/cards/sedeva.html |date=25 August 2006 }}, from Aquinas publishing</ref>

The particular congregation that deals with the day-to-day matters of the Church includes the cardinal camerlengo and the three cardinal assistants—one cardinal bishop, one cardinal priest and one cardinal deacon—chosen by lot. Every three days, new cardinal assistants are chosen by lot. The camerlengo and assistants are responsible, among other things, for maintaining the election's secrecy.<ref name=":6" />

The congregations must make certain arrangements in respect of the pope's burial, which by tradition takes place within four to six days of the pope's death, leaving time for pilgrims to see the dead pontiff, and occurs within a nine-day period of mourning known as the {{langnf|la|novemdiales|nine days}}. The congregations also fix the date and time of the commencement of the conclave. The conclave normally takes place fifteen days after the death of the pope, but the congregations may extend the period to a maximum of twenty days in order to permit other cardinals to arrive in Vatican City.<ref>For a description of [[John Paul II]]'s burial see [http://news.bbc.co.uk/1/hi/programmes/from_our_own_correspondent/4422629.stm A pope among popes] {{Webarchive|url=https://web.archive.org/web/20060619174227/http://news.bbc.co.uk/1/hi/programmes/from_our_own_correspondent/4422629.stm |date=19 June 2006 }}</ref>

===Resignation of a pope===
{{Main|Papal resignation}}
A vacancy in the papal office may also result from a [[papal resignation]]. Until the [[resignation of Benedict XVI]] on 28 February 2013, no pope had resigned since [[Pope Gregory XII|Gregory XII]] in 1415.<ref>{{CathEncy | wstitle=Pope Gregory XII | author=Ott, Michael T.}}</ref> In 1996, Pope John Paul II, in his [[apostolic constitution]] ''Universi Dominici gregis'', anticipated the possibility of resignation when he specified that the procedures he set out in that document should be observed "even if the vacancy of the Apostolic See should occur as a result of the resignation of the Supreme Pontiff".<ref>{{cite web|url=https://w2.vatican.va/content/john-paul-ii/en/apost_constitutions/documents/hf_jp-ii_apc_22021996_universi-dominici-gregis.html|at=para. 77|title=Universi Dominici Gregis|author=Pope John Paul II|date=22 February 1996|website=The Holy See|publisher=Libreria Editrice Vaticana |access-date=7 September 2017}}</ref>

In the case of a papal resignation, the Ring of the Fisherman is placed in the custody of the cardinal camerlengo; in the presence of the College of Cardinals, the camerlengo marks an "X" (for the cross) with a small silver hammer and chisel into the ring, disfiguring it so it may no longer be used for signing and sealing official papal documents.

In his book ''Light of the World: The Pope, the Church and the Signs of the Times'', Pope Benedict XVI espoused the idea of resignation on health grounds, which already had some theological respectability.<ref>{{cite news|url=https://www.telegraph.co.uk/news/religion/the-pope/9862770/Pope-resigns-The-pope-who-was-not-afraid-to-say-sorry.html|archive-url=https://web.archive.org/web/20130212113243/http://www.telegraph.co.uk/news/religion/the-pope/9862770/Pope-resigns-The-pope-who-was-not-afraid-to-say-sorry.html|archive-date=12 February 2013|title=Pope resigns: The pope who was not afraid to say sorry|last=Stanford|first=Peter|newspaper=The Daily Telegraph|access-date=12 February 2013}}</ref>

===Before the sealing of the Sistine Chapel===
The cardinals hear two sermons before the election: one before actually entering the conclave, and one once they are settled in the Sistine Chapel. In both cases, the sermons are meant to lay out the current state of the Church, and to suggest the qualities necessary for a pope to possess in that specific time. The first preacher in the 2005 conclave was [[Raniero Cantalamessa]], the preacher of the [[papal household]] and a member of the [[Order of Friars Minor Capuchin|Capuchin Franciscan order]], who spoke at one of the meetings of the cardinals held before the actual day when the conclave began.<ref>See the [http://www.cantalamessa.org/en/index.php home page] {{webarchive|url=https://web.archive.org/web/20060829083333/http://www.cantalamessa.org/en/index.php |date=29 August 2006 }} here</ref> Cardinal [[Tomáš Špidlík]], a former professor at the [[Pontifical Oriental Institute]] and a non-voting member (due to age) of the College of Cardinals, spoke just before the doors were closed for the conclave.<ref>Homepage for [http://www.centroaletti.com/en/e-spidlik.htm Card.

On the morning of the day designated by the congregations of cardinals, the cardinal electors assemble in [[Saint Peter's Basilica]] to celebrate [[Mass (liturgy)|Mass]]. Then they gather in the afternoon in the [[Cappella Paolina|Pauline Chapel]] in the [[Apostolic Palace]] and [[procession|process]] to the Sistine Chapel while singing the [[Litany of the Saints]]. The cardinals will sing the "[[Veni Creator Spiritus]]", invoking the [[Holy Spirit in Christianity|Holy Spirit]],<ref>{{cite web|title=Veni Creator Spiritus|url=http://www.newadvent.org/cathen/15341a.htm|website=Catholic Encyclopedia|publisher=New Advent|access-date=11 August 2016}}</ref> then take an oath to observe the procedures set down by the apostolic constitutions; to, if elected, defend the liberty of the [[Holy See]]; to maintain secrecy; and to disregard the instructions of secular authorities on voting. The senior cardinal reads the oath aloud in full. In [[Order of precedence in the Catholic Church|order of precedence]] the other cardinal electors repeat the oath, while touching the [[Gospels]]. Where their rank is the same, their seniority is taken as precedence. The oath is:<ref>[https://www.youtube.com/watch?v=rS_OT0qUkTw Cardinals begin voting for new Pope] {{Webarchive|url=https://web.archive.org/web/20150713232915/https://www.youtube.com/watch?v=rS_OT0qUkTw |date=13 July 2015 }} (video, at 2:40 mins), [[Daily Telegraph]], 12 March 2013.

So help me God and these Holy Gospels, which I touch with my hand.}}</blockquote>

===Expelling the outsiders===
After all the cardinals present have taken the oath, the master of papal liturgical celebrations orders all individuals other than the cardinal electors and conclave participants to leave the chapel. Traditionally, he stands at the door of the Sistine Chapel and calls out: {{langnf|la|"''Extra omnes!''"|italic=unset|Outside, all [of you]}}. He then closes the door.<ref>[https://www.pbs.org/newshour/extra/features/jan-june05/pope_4-04.html Cardinals Gather to Mourn Pope, Choose Successor] {{Webarchive|url=https://web.archive.org/web/20130928111351/http://www.pbs.org/newshour/extra/features/jan-june05/pope_4-04.html |date=28 September 2013 }}, 04.04.05, Newshour,</ref> In modern practice, the master need not stand at the door to perform this duty.

The master himself may remain, as may one ecclesiastic designated by the congregations prior to the commencement of the election. The ecclesiastic makes a speech concerning the problems facing the Church and on the qualities the new pope needs to have. After the speech concludes, the ecclesiastic leaves. Following the recitation of prayers, the senior cardinal asks if any doubts relating to procedure remain. After the clarification of the doubts, if any, the election proper may commence. Cardinals who arrive after the conclave has begun are admitted nevertheless. A cardinal who becomes ill or needs to use the restroom may leave the conclave and later be readmitted, but a cardinal who leaves for any other reason may not return.<ref>If a cardinal with the right to vote should refuse to enter Vatican City in order to take part in the election, or subsequently, once the election has begun, should refuse to remain in order to discharge his office, without manifest reason of illness attested to under oath by doctors and confirmed by the majority of the electors, the other cardinals shall proceed freely with the election, without waiting for him or readmitting him.

Although in the past cardinal electors could be accompanied by attendants ("[[conclavist]]s"), now the only permitted attendant is a [[nurse]] if the Congregation of Cardinals confirms that a cardinal in ill-health requires one. A nurse is permitted during the period of election if necessary. The secretary of the College of Cardinals, the master of papal liturgical celebrations, two [[Master of ceremonies|masters of ceremonies]], two officers of the Papal Sacristy and an ecclesiastic assisting the dean of the College of Cardinals are admitted to the conclave. Priests are available to hear [[Sacrament of Penance|confessions]] in different languages. Two doctors are also admitted. A strictly limited number of servant staff are permitted for housekeeping and the preparing and serving of meals. All require prior approval from the Cardinal Camerlengo and the three Cardinal Assistants.<ref name="UDG" />

Secrecy is maintained during the conclave. The cardinals and staff are forbidden to disclose any information relating to the election. They may not correspond or converse with anyone outside the conclave by any means. Violating this oath, or an outsider [[eavesdropping]], is punished by [[excommunication]] ''[[latae sententiae]]''. Only three cardinal electors are permitted to communicate with the outside world under grave circumstances, with the prior approval of the college, to fulfill their duties: the [[Major Penitentiary]], the [[Cardinal Vicar|cardinal vicar]] for the [[Diocese of Rome]], and the [[Vicar General for the Vatican City State|vicar general for the Vatican City State]].<ref name="UDG" />

Before the conclave that elected Pope Francis, the Sistine Chapel was "[[Bug sweep|swept]]" to detect any hidden "[[covert listening device|bugs]]" or surveillance devices. There were no reports that any were found, but in previous conclaves press reporters who had disguised themselves as conclave servants were discovered. ''Universi Dominici gregis'' specifically prohibits media such as newspapers, the radio, and television.<ref>[http://news.bbc.co.uk/1/shared/spl/hi/world/pope/choosing/html/conclave.stm 2 – Secret conclave] {{Webarchive|url=https://web.archive.org/web/20050420072926/http://news.bbc.co.uk/1/shared/spl/hi/world/pope/choosing/html/conclave.stm |date=20 April 2005 }}, from the BBC</ref> [[Wi-Fi]] access is blocked in Vatican City.

===Voting===
[[File:Folded conclave ballot.jpg|thumb|Cardinals formerly used these intricate ballot papers, one of which is shown folded above. The text Latin reads "Name" and "Signature" at bottom, with the middle text translating to, "I choose as Supreme Pontiff my most reverend lord, the Lord Cardinal [name]." Currently, the [[ballot]]s are simple cards, folded once, like a note card, with the words "I elect as Supreme Pontiff" printed in Latin on them.]]
[[File:Card. Mahony's Scrutiny Ballot, 2013.jpg|thumb|Today, cardinal electors receive copies of multiple ballot cards, scrutiny ballots, and a copy of ''Ordo Rituum Conclavis'' (Order of Conclave Rites). Shown above are the ballot papers of Cardinal [[Roger Mahony]] used in the [[Papal conclave, 2013|2013 conclave]].]]
On the afternoon of the first day, one ballot (referred to as a "scrutiny") may be held, but is not required. A maximum of four ballots are held on each successive day: two in each morning and two in each afternoon. Before voting in the morning and again before voting in the afternoon, the electors take an oath to obey the rules of the conclave.<ref name="BXVI-MP" />

If no result is obtained after three vote days of balloting, the process is suspended for a maximum of one day for prayer and an address by the senior cardinal deacon. After seven further ballots, the process may again be similarly suspended, with the address now being delivered by the senior cardinal priest. If, after another seven ballots, no result is achieved, voting is suspended once more, the address being delivered by the senior cardinal bishop.<ref name="BXVI-MP" />

After a further seven ballots, there shall be a day of prayer, reflection and dialogue. In the following ballots, only the two names who received the most votes in the last ballot shall be eligible in a [[runoff election]] where a two-thirds majority is still required. The two people voted on, even if cardinal electors, shall not themselves have the right to vote.<ref name="BXVI-MP" />

The process of voting consist of three phases: the "pre-scrutiny", the "scrutiny", and the "post-scrutiny".

====Pre-scrutiny====
During the pre-scrutiny, the masters of ceremonies prepare ballot papers bearing the words {{lang|la|Eligo in Summum Pontificem}} ('I elect as Supreme Pontiff') and provide at least two to each cardinal elector. As the cardinals begin to write their votes, the secretary of the College of Cardinals, the master of papal liturgical celebrations and the masters of ceremonies exit. The junior cardinal deacon then closes the door.<ref name=":1">''Universi Dominici gregis'' (Shepherd of the Lord's Whole Flock), promulgated by Pope John Paul II, 22 February 1995</ref>

During the first pre-scrutiny of any given morning, the junior cardinal deacon randomly draws nine names. The first three cardinals so chosen become scrutineers, the second three {{lang|la|infirmarii}} and the last three revisers. These cardinals retain their roles for the second scrutiny of the morning, if it is needed.<ref name=":1" />

If both morning scrutinies fail to produce a result, the cardinals re-take the oath to obey the rules of the conclave once they have eaten lunch and again gathered in the Sistine Chapel. A drawing is held to choose new scrutineers, ''infirmarii'', and revisers, and the third scrutiny of the day is then held, immediately followed by a fourth if necessary.<ref name=":1" />

No changes in these rules were made by Benedict XVI in 2007. These were the rules followed, so far as is known, given the secrecy of a conclave, in electing Pope Leo XIV in May 2025.

====Scrutiny====
[[File:Conclave 1903 scrutin.jpg|thumb|Scrutiny during the [[1903 conclave|conclave of 1903]]]]
In order of precedence, the cardinals approach the scrutineers at the altar and deposit their ballots into a receptacle there. Each ballot bears only the name of the candidate selected by its holder, who recites the following Latin oath before casting it:

<blockquote>{{Verse translation|{{lang|la|Testor Christum Dominum, qui me iudicaturus est, me eum eligere, quem secundum Deum iudico eligi debere.}}|I call as my witness Christ the Lord, who is to judge me, that I choose him whom according to God I judge ought to be elected.}}</blockquote>

If any cardinal elector is in the chapel, but cannot proceed to the altar due to infirmity, the last scrutineer may go to him and take his ballot after he has recited the oath. If any cardinal electors are confined to their rooms for this reason, the {{lang|la|infirmarii}} go to their rooms with ballot papers and a box. These cardinals fill out their ballots, recite the oath, and place them in the box. When the {{lang|la|infirmarii}} return to the chapel, the ballots are counted to ensure that their number matches with the number of ill cardinals, whereupon they are transferred to the receptacle holding the ballots cast by those in the chapel.

If no candidate receives a two-thirds vote on the first scrutiny, then a second scrutiny immediately follows. A maximum of four scrutinies can be carried out per day, two apiece in the morning and afternoon.

Under present rules, the oath that cardinals take when casting their votes is only verbal, since they no longer sign their names on the ballots. Previous rules required each cardinal to sign his ballot and mark it with a unique identification code, or motif. He then folded the ballot in two places to cover his signature and motif, leaving only the name of his chosen candidate exposed, and sealed it with wax to create a semi-secret ballot.<ref name=":2">Ludwig Von Pastor, History of the Papacy, the Bulls of Gregory XV, Aeterni Patris, and Decet Romanum Pontificem 1621–1622.</ref>

The wax seals were opened only if a candidate received the bare minimum needed for election. This was to ensure that the apparently elected man had not voted for himself. This was the procedure from 1621 to 1945. The example above is a copy of the three section semi-secret ballot, which was last used in the conclave of 1939. There was no oath taken when actually casting ballots, prior to 1621.<ref name=":2" />

Semi-secret ballots with initials or motif written on the back of the ballot, at the option of the cardinals present and voting, were sometimes used prior to 1621. These secret ballots had no oath taken when the vote was actually cast. At some conclaves prior to 1621, the cardinals verbally voted and sometimes stood in groups to facilitate counting the votes cast. The signature and motif of the elector covered by two folded-over parts of the ballot paper was added by Gregory XV in 1621, to prevent anyone from casting the deciding vote for himself.<ref name=":3">Francis Burkle Young, Conclaves in the 15th century; also see Cardinals of the Holy Roman Church, a website maintained by Salvador Miranda, via FIU</ref>

In 1549, [[Reginald Pole|Cardinal Pole]] of England refused to cast the deciding vote for himself, which would then have been followed by the accession to raise his vote total to at least one more than the minimum number needed, and was not elected. In 1492, Cardinal Borgia ([[Pope Alexander VI]]) almost certainly privately bribed other cardinals to vote for him. It is certain that he would not have been allowed to cast the deciding vote for himself, without the knowledge and consent of the other cardinals. A procedure called accession gave electors who had not voted for the possible new pope the opportunity to change their votes and make the election unanimous, or nearly so, (except for the vote of the possible new pope). This is how Cardinal Borgia was elected [[Pope Alexander VI]] in 1492.<ref name=":3" />

Faced by the mortal challenge to the papacy emanating from [[Protestantism]], and fearing schism due to several stormy conclaves in the late 16th and early 17th centuries, [[Pope Gregory XV|Gregory XV]] established the procedure of signed ballots to prevent any cardinal from casting the deciding vote for himself. The accession was not ended, but was seldom used until [[Pope Pius XII|Pius XII]] abolished it in 1945.<ref>Ludwig Von Pastor, History of the Papacy,</ref> Since 1945, a cardinal can cast the deciding vote for himself without the accession, though the two-thirds majority rule has always been continued, except when John Paul II had modified that rule in 1996, after 33 ballots, a simple majority being sufficient. The two-thirds majority rule was restored in 2007 by Benedict XVI.<ref name="Bxvi-al">Benedict XVI (11 June 2007) [https://www.vatican.va/holy_father/benedict_xvi/motu_proprio/documents/hf_ben-xvi_motu-proprio_20070611_de-electione_lt.html " De aliquibus mutationibus in normis de electione Romani Pontificis"] {{Webarchive|url=https://web.archive.org/web/20171222062902/http://w2.vatican.va/content/benedict-xvi/la/motu_proprio/documents/hf_ben-xvi_motu-proprio_20070611_de-electione.html |date=22 December 2017 }} Apostolic letter.</ref>

Prior to 1621, the only oath taken was that of obedience to the rules of the conclave in force at that time, when the cardinals entered the conclave and the doors were locked, and each morning and afternoon as they entered the Sistine Chapel to vote. Gregory XV added the additional oath, taken when each cardinal casts his ballot, to prevent cardinals wasting time in casting "courtesy votes" and instead narrowing the number of realistic candidates for the papal throne to perhaps only two or three. Speed in electing a pope was important, and that meant using an oath so as to get the cardinals down to the serious business of electing a new pope and narrowing the number of potentially electable candidates.<ref name=":4">Vacantis Apostolicae Sedis, 8 December 1945, Pope Pius XII</ref><ref name=":5">Vacante Sede Apostolica, 25 December 1904 Pope Pius X</ref>

The reforms of Gregory XV in 1621 and reaffirmed in 1622 created the written detailed step-by-step procedure used in choosing a pope; a procedure that was essentially the same as the process used in 2025 to elect Pope Leo XIV. The biggest change since 1621 was the elimination of the rule that required the electors to sign their ballots, resulting in the detailed voting procedure of scrutiny making use of simple verbal oaths. Beginning in 1945, an elector could vote for himself and then call on God via the oath taken when the vote is dropped into the receptacle, to declare himself to be the best one qualified for the papacy. The use of the accession would prevent this, but is not allowed under the present rules.<ref name=":4" /><ref name=":5" /> Beginning with the use of totally secret ballots in the 1958 conclave, it is now possible for a cardinal to cast the deciding vote for himself, without the knowledge and consent of the other cardinals.

Once all votes have been cast, the first scrutineer chosen shakes the container, and the last scrutineer removes and counts the ballots. If the number of ballots does not correspond to the number of cardinal electors present, including sick cardinals in their rooms, the ballots are burnt, unread, and the vote is repeated. If no irregularities are observed, the ballots may be opened and the votes counted. Each ballot is unfolded by the first scrutineer. All three scrutineers separately write down the name indicated on the ballot. The last of the scrutineers reads the name aloud.

Once all of the ballots have been opened, the final post-scrutiny phase begins.

====Post-scrutiny====
[[File:Konklave – pálení hlasovacích lístků (Pestrý týden, 4. 3. 1939).jpg|thumb|Illustration of the burning of ballots (1939)]]
The scrutineers add up all of the votes, and the revisers check the ballots and the names on the scrutineers' lists to ensure that no error has been made. The ballots are then stitched together with a needle and red thread and burned by the scrutineers with the assistance of the secretary of the College of Cardinals and the masters of ceremonies. If the first scrutiny held in any given morning or afternoon does not result in an election, the cardinals proceed to the next scrutiny immediately. The papers from both scrutinies are then burned together at the end of the second scrutiny.

====Fumata====

Until 1945, when Pius XII changed the form of ballot to use the unsigned ballots first used in 1958, the sealing wax on the complex type ballots illustrated above had the effect of making the smoke from burning the ballots either black or white, depending on whether or not damp straw was added. Until the 20th century, sealing wax customarily had beeswax mixed into its composition. Burning wax made solely from animal fat does not give as much white smoke as does wax that includes beeswax.<ref name=Beehivecandles.com> Beehivecandles.com </ref>

In the [[1939 papal conclave|1939 conclave]], there was some confusion over the smoke color, which was even more apparent in the [[1958 papal conclave|1958 conclave]]. The lack of sealing wax on the ballots likely explains the confusion over the color of the smoke in the 1958 conclave. The [[Siri thesis]] was based on the confusion over the smoke color on the first day of that conclave.<ref name=Siri> "Guiffre" </ref>

Since 1963 chemicals have been added to the burning process to augment the smoke's black or white color. Since 2005, a successful election has been announced by the bells of Saint Peter's Basilica ringing at the appearance of the white smoke.<ref>[http://news.bbc.co.uk/1/shared/spl/hi/world/pope/choosing/html/rituals.stm 3 – Voting rituals] ({{Webarchive|url=https://web.archive.org/web/20060409203846/http://news.bbc.co.uk/1/shared/spl/hi/world/pope/choosing/html/rituals.stm |date=9 April 2006 }}), from the BBC series "Choosing a Pope"</ref>

===Acceptance and proclamation===
Once the election concludes, the cardinal dean summons the secretary of the College of Cardinals and the master of papal liturgical celebrations into the hall. The dean then asks the pope-elect if he assents to the election, saying in Latin: {{lang|la|Acceptasne electionem de te canonice factam in Summum Pontificem?}} ("Do you accept your canonical election as Supreme Pontiff?") There is no requirement that the pope-elect do so, and he is free to respond {{lang|la|Non accepto}} ("I do not accept").

In practice, any cardinal who intends not to accept will explicitly state this ''before'' he receives a sufficient number of votes to become pope, as [[Giovanni Colombo]] did in [[October 1978 papal conclave|October 1978]].<ref>Thomas J. Reese SJ, ''Inside the Vatican: The Politics and Organization of the Catholic Church'', Harvard University Press (1996), p. 99.</ref><ref>Menachery George, Vatican Adventure http://www.indianchristianity.com/html/menachery/html/GeorgeMenachery.htm {{Webarchive|url=https://web.archive.org/web/20171214041643/http://www.indianchristianity.com/html/menachery/html/GeorgeMenachery.htm |date=14 December 2017 }}</ref>

====Consecration====
If he accepts, and is already a bishop, he immediately takes office. If he is not a bishop, he must be first consecrated as one before he can assume office. If a priest is elected, the dean of the College of Cardinals consecrates him bishop. If a layman is elected, then the dean first ordains him deacon, then priest, and then consecrates him as bishop. After becoming a bishop the pope-elect takes office. These functions of the dean are assumed, if necessary, by the sub-dean. If the sub-dean is also impeded, they are assumed by the senior cardinal bishop in attendance. 

Since the imposition of the age-restrictions on Cardinals aged 80 and older by [[Pope Paul VI]] in 1970, the [[Dean of the College of Cardinals]] has participated in a conclave only once, and has never confirmed the election of an elected Pope. [[Jean Villot|Jean Marie Villot]] presided the [[August 1978 papal conclave|August 1978]] and [[October 1978 papal conclave|October 1978]] papal conclaves on behalf of then-Dean [[Carlo Confalonieri]], and confirmed the elections of [[Pope John Paul I|Albino Luciani]] and [[Pope John Paul II|Karol Wojtyla]], respectively. In [[2005 papal conclave|2005]], because [[Pope Benedict XVI|Joseph Ratzinger]], the dean, was elected Pope, the duties of confirming the election fell into the hands of the vice-dean, [[Angelo Sodano]]. In [[2013 papal conclave|2013]], [[Giovanni Battista Re]] was the senior cardinal bishop (who later became dean himself in 2020) who confirmed the election of [[Pope Francis|Jorge Mario Bergoglio]]. In [[2025 papal conclave|2025]], the presiding cardinal over the conclave was [[Pietro Parolin]] who is confirmed the election of [[Pope Leo XIV|Robert Francis Prevost]].

====Papal name====
Since 533,<ref name="ce-john">{{Catholic|wstitle=Pope John II|first=Horace K.|last=Mann|volume=8|inline=1}}</ref> the new pope has also decided on his regnal name. [[Pope John II]] was the first to adopt a new [[papal name]]. He felt that his original name, Mercurius, was inappropriate, as it was also the name of a [[Mercury (mythology)|Roman god]]. In most cases, even if such considerations are absent, popes tend to choose papal names different from their baptismal names. The last pope to reign under his baptismal name was [[Pope Marcellus II]] (1555). After the newly elected pope accepts his election, the dean asks him about his papal name, saying in Latin: {{lang|la|Quo nomine vis vocari?}} ("By what name do you wish to be called?"). After the pope-elect has taken time to think about the papal name he chooses (sometimes with some help from other cardinals), the officials are readmitted to the conclave, and the master of papal liturgical celebrations writes a document recording the acceptance and the new name of the pope.

====Canopies====
In the past, when the cardinals voted during a conclave, they sat on [[Canopy (architecture)|canopied]] thrones symbolizing the cardinals' collective governance of the church during the period of ''sede vacante''.<ref name="wintle" /> Upon the acceptance by the new pope of his election, all other cardinals in attendance each pulled a cord and lowered the canopies above their respective thrones, signifying an end to the period of collective governance, with only the newly elected pope's canopy remained unlowered.<ref name="wintle" /> The last time canopied thrones were used was during the [[1963 papal conclave|1963 conclave]].<ref name="PapalConclave1963">[https://www.youtube.com/watch?v=-orhFzr2xeY Conclave A.D. 1963 – Election of Pope Paul VI] {{Webarchive|url=https://web.archive.org/web/20160409044709/https://www.youtube.com/watch?v=-orhFzr2xeY |date=9 April 2016 }}.

The amount of rows were bumped up to six in 2025.

====Secretary tradition====
At the end of the conclave, the new pope could give his [[wikt:cardinalitial|cardinalitial]] [[zucchetto]] or skull cap to the secretary of the conclave, indicating the secretary would be made cardinal at the next consistory to create cardinals. Prior to the 2013 conclave, this tradition was last followed at the 1958 conclave by the newly elected [[Pope John XXIII]], who bestowed his cardinal's skull cap on [[Alberto di Jorio]] and created him a cardinal at the consistory on 15 December 1958. In 2013, the Portuguese section of [[Vatican Radio]] reported that at the conclusion of the 2013 conclave, the newly elected Pope Francis bestowed his cardinalitial zucchetto on Archbishop [[Lorenzo Baldisseri]], the secretary of that conclave.<ref name="Baldisseri news">{{cite web|url=http://pt.radiovaticana.va/news/2013/03/16/dom_lorenzo_baldisseri_recebe_solideu_cardinal%C3%ADcio/bra-673713|title=Dom Lorenzo Baldisseri recebe solideu cardinalício|publisher=Rádio Vaticano Portuguese section|language=pt}}</ref> On 22 February 2014, at Pope Francis' first consistory, Baldisseri was formally made a cardinal with the title of Cardinal-Deacon of Sant'Anselmo all'Aventino.<ref>{{cite web | url=http://www.news.va/en/news/166955 | title=Annuncio di Concistoro per la Creazione di Nuovi Cardinali | publisher=[[The Vatican Today]] | date=12 January 2014 | access-date=12 January 2014 | language=it | archive-date=14 December 2017 | archive-url=https://web.archive.org/web/20171214043451/http://www.news.va/en/news/166955 }}</ref>

====Room of Tears====
The new pope goes to the [[Room of Tears]], a small red room next to the Sistine Chapel. The room carries the nickname because of the strong emotions experienced by the new pope. The new pope dresses by himself, choosing a set of pontifical robes—consisting of a white [[cassock]], [[rochet]], and red [[mozzetta]]—from three sizes provided. He then dons a gold corded [[pectoral cross]], a red and gold embroidered [[Stole (vestment)|stole]], and then the white papal zucchetto on his head. In 2013, [[Pope Francis]] departed from tradition by forgoing the red mozzetta, rochet, and gold pectoral cross, appearing on the central balcony in only the white cassock and his personal pectoral cross. He donned the stole solely to impart the [[apostolic blessing]], removing it immediately afterward. In 2025, [[Pope Leo XIV]] chose to return to the traditional attire, appearing in the red mozzetta, rochet, gold pectoral cross, and stole.

====Proclamation====
Next, the [[protodeacon of the College of Cardinals]], the senior cardinal deacon, appears at the [[loggia]] of the basilica to proclaim the new pope. He usually proceeds with the following traditional Latin formula, assuming that a cardinal has been elected:<ref>{{cite web|url=https://press.vatican.va/content/salastampa/it/bollettino/pubblico/2013/03/13/0147/00367.html|title=L'annuncio dell'elezione del Papa|date=13 March 2013|website=[[Holy See Press Office|Sala Stampa della Santa Sede]]|trans-title=Announcement of the election of the Pope|access-date=1 April 2020|archive-url=https://web.archive.org/web/20141004031917/https://press.vatican.va/content/salastampa/it/bollettino/pubblico/2013/03/13/0147/00367.html|archive-date=4 October 2014|url-status=live}}</ref>

<blockquote>{{Verse translation|{{lang|la|Annuntio vobis gaudium magnum;<br>[[habemus papam]]:<br>Eminentissimum ac Reverendissimum Dominum,<br>Dominum}} [prænomen]<br>{{lang|la|Sanctae Romanae Ecclesiae Cardinalem}} [nomen]<br>{{lang|la|qui sibi nomen imposuit}} [nomen pontificale].|I announce to you a great joy;<br>we have a pope:<br>The Most Eminent and Most Reverend Lord,<br>Lord [forename]<br>Cardinal of the Holy Roman Church [surname]<br>who has taken the name [papal name].}}</blockquote>

During the announcement for Pope Benedict XVI's election, the protodeacon, Cardinal [[Jorge Medina (cardinal)|Jorge Medina]], first greeted the crowds with "Dear brothers and sisters" in several different languages before proceeding to the Latin announcement. This was not done when Pope Francis and Pope Leo XIV were elected.

In the past, the protodeacon has himself been elected pope. In such an event, the announcement is made by the next senior deacon, who has thus succeeded as protodeacon. The last time the cardinal protodeacon was elected was in 1513, when Giovanni de Medici was elected as [[Pope Leo X]] and the next senior cardinal deacon [[Pope Paul III|Alessandro Farnese]] (the future [[Pope Paul III]]) made the announcement. After the election of [[Pope Leo XIII]] in 1878, Protodeacon [[Prospero Caterini]] appeared and started to make the announcement but was [[Stage fright|physically incapable of completing it]], so another made it for him.{{efn|Richard Henry Clarke's book about Leo XIII claims that Prospero Caterini made the announcement<ref name="Clarke 1878">{{cite book|title=The life of His Holiness Pope Leo XIII ...: together with extracts from his pastorals and encyclicals|url=https://books.google.com/books?id=xCEMAQAAMAAJ&q=papal+elections+%26+Caterini&pg=PA210|author=Richard Henry Clarke|year = 1903}}</ref> and Salvador Miranda's entry on Cardinal Caterini at ''The Cardinals of the Holy Roman Church'' website mentions Caterini as having given the announcement<ref name=Caterini>{{cite web|url=http://www.fiu.edu/~mirandas/bios1853.htm#Caterini|work=Cardinals of the Holy Roman Church|title=Caterini, Prospero|access-date=8 February 2014|archive-date=30 July 2014|archive-url=https://web.archive.org/web/20140730014931/http://www2.fiu.edu/~mirandas/bios1853.htm#Caterini|url-status=dead}}</ref> but Francis Burkle-Young claims that Caterini started to make the announcement but was incapable of completing the spoken formula and was ultimately assisted by Bartolomeo Grassi-Landi, a non-cardinal and the conclavist of Cardinal [[Luigi Oreglia di Santo Stefano]]<ref name="Burkle-Young 1878">{{cite book|title=Papal Elections in the Age of Transition, 1878–1922|url=https://books.google.com/books?id=t9QxJMdp6FMC&q=papal+elections+%26+Caterini&pg=PA68|author=Francis A.

Following the announcement, the senior cardinal deacon retreats, and papal aides unfurl a large, maroon banner that out of practicality often bears the late pope's arms in the centre, draping it onto the railing of the basilica's loggia.<ref>Menachery George, Vatican Adventure, Election of John Paul II, http://www.indianchristianity.com/html/menachery/html/GeorgeMenachery.htm {{Webarchive|url=https://web.archive.org/web/20171214041643/http://www.indianchristianity.com/html/menachery/html/GeorgeMenachery.htm |date=14 December 2017 }}</ref> During John Paul II's announcement, the inner portion of the arms of Paul VI were simply covered due to the short pontificate of John Paul I not allowing sufficient time for a banner with the latter's arms to be created. For Francis's announcement, there was no image of his predecessor's arms due to Benedict XVI still being alive. For Leo XIV's announcement, the banner featured the [[Coat of arms of the Holy See|arms of the Holy See]]. During [[Pope Pius XI]]'s first appearance following his election at the [[Papal conclave, 1922|1922 conclave]], the banner showed the arms of [[Pope Pius IX]] instead of the arms of his immediate predecessor [[Pope Benedict XV]].<ref>See for example the image at the article "How new Pope is elected" at Pophap {{cite web |url=http://www.pophap.com/how-new-pope-is-elected/ |title=How new Pope is elected – POPHAPPOPHAP |access-date=2 June 2013 |archive-url=https://web.archive.org/web/20131220094015/http://www.pophap.com/how-new-pope-is-elected/ |archive-date=20 December 2013 }}</ref>

The new pope then emerges onto the balcony to the adulation of the crowd, while a brass band in the forecourt below plays the [[Pontifical Anthem]]. He then imparts the {{lang|la|[[Urbi et Orbi]]}} blessing. The pope may on this occasion choose to give the shorter [[episcopal blessing]] as his first apostolic blessing instead of the traditional {{lang|la|Urbi et Orbi}} blessing. This happened most recently with [[Pope Paul VI]] after his election at the [[1963 papal conclave|1963 conclave]].<ref>[https://www.youtube.com/watch?v=PhIh7xYEy_0 Elezione Papa Paolo VI (1963)] {{Webarchive|url=https://web.archive.org/web/20140123163931/http://www.youtube.com/watch?v=PhIh7xYEy_0 |date=23 January 2014 }}. YouTube. Accessed on 22 December 2012.</ref>

Beginning with Pope John Paul II, the last four popes elected, including [[Pope Leo XIV]], have chosen to address the crowds first before imparting the {{lang|la|Urbi et Orbi}} blessing. Also, at Pope Francis's first appearance, he first led the faithful in prayers for his predecessor and then asked them to pray for himself, before imparting the {{lang|la|Urbi et Orbi}} blessing. Pope Leo XIV spoke in Spanish in part of his remarks, the first time a pope has used a language to address a crowd other than Italian{{Citation needed|date=May 2025|reason=+what about Latin?}} following a conclave. Leo XIV was also the first observed to have used written notes while addressing the crowd.

====Coronation and inauguration====
Formerly, the popes were crowned by the {{lang|la|[[Papal Tiara|triregnum]]}}, or triple tiara, at the [[papal coronation]]. All popes since [[Pope John Paul I|John Paul I]] have refused an elaborate coronation, choosing instead to have a simpler [[papal inauguration]] ceremony.<ref>[http://news.bbc.co.uk/1/shared/spl/hi/world/pope/choosing/html/announcement.stm "5 – New pope announced"].

* The [[Dan Brown]] novel ''[[Angels & Demons]]'' (2000), itself adapted onto [[Angels & Demons (film)|a film in 2009]], concerns four papabile being kidnapped right as the conclave starts, and their murders cause much concern to the other cardinals.<ref>{{cite web|url=https://bustedhalo.com/blogs/angels-demons-and-conclave-2013-true-or-false|title=Angels & Demons and Conclave 2013: True or False?|publisher=Busted Halo|author= Sullivan, Louis|date=12 March 2013 |access-date=28 April 2025}}</ref>
* A papal conclave is the subject of the 2024 film [[Conclave (film)|''Conclave'']], itself adapted from [[Conclave (novel)|a 2016 novel]]. While the [[Cardinal (Catholic Church)|cardinals]] and plot are fictional and dramatised, the rituals are correctly shown, according to experts. Some of the rituals include the sequestering in the Sistine Chapel, the burning of ballots, the use of smoke signals, and the destruction of a deceased pope's ring.<ref>{{Cite web |last=CNA |title='Conclave' Fact Vs.
