It may also be translated as "[[Khan (title)|Khan]] of Khans",<ref>{{Cite book |url=https://books.google.com/books?id=zQhDAQAAMAAJ&pg=PA203 |volume=21|page=203 |title=Alden's Manifold Cyclopedia of Knowledge and Language |date=1890 |publisher=J. B. Alden |language=en}}</ref> equivalent to [[King of Kings]]. In Bulgarian, the title became known as ''Khan'',{{efn|As in the ''[[Nominalia of the Bulgarian Khans]]'', {{lang|bg|Именник на българските ханове}}.}}{{clarify|reason=Khan is a title in its own right|date=January 2025}} while in modern Turkic, the title became ''Khaan'' with the ''g'' sound becoming almost silent{{efn|i.e. a very light [[voiceless velar fricative]]}} or non-existent; the ''ğ'' in modern [[Turkish language|Turkish]] ''Kağan'' is also silent. After the [[division of the Mongol Empire]], monarchs of the [[Yuan dynasty]] and the [[Northern Yuan]] held the title of ''Khagan''. ''Kağan, Hakan'' and ''Kaan'', [[Turkish language|Turkish]] equivalents of the title are common [[Turkish names]] in [[Turkey]].

The common western rendering as '''Great Khan''' (or ''Grand Khan''), notably in the case of the [[Mongol Empire]], is a translation of ''Yekhe Khagan'' (''Great Emperor'' or ''{{lang|mn|Их Хаан}}'').

== Etymology ==
The term is of unknown origin and possibly a loanword from the [[Rouran language]].<ref>Vovin, Alexander (2010). "Once Again on the Ruan-ruan language." ''Ötüken'den İstanbul'a Türkçenin 1290 Yılı (720–2010) Sempozyumu / From Ötüken to Istanbul, 1290 Years of Turkish (720–2010).'' 3–5 Aralık 2010, İstanbul / 3–5 December 2010, İstanbul, pp. 1–10.</ref> Canadian sinologist [[Edwin G. Pulleyblank]] (1962) first suggested that a [[Xiongnu]] title, transcribed as {{lang|zh|護于}} ([[Old Chinese]]: *''hʷaʔ-hʷaʰ'') might have been the original behind [[Turkic languages|Turkic]] ''qaɣan'' ~ ''xaɣan''.<ref name=Vovin_2007>Vovin, Alexander (2007). "Once again on the etymology of the title ''qaγan''". ''Studia Etymologica Cracoviensia'', vol. 12 ([http://ejournals.eu/sj/index.php/SEC/article/viewFile/1100/1096 online ressource])</ref> According to [[Alexander Vovin|Vovin]] (2007, 2010) the term comes from ''qaγan'' (meaning "[[emperor]]" or "supreme ruler") and was later borrowed and used in several languages, especially in Turkic and Mongolic.

[[Turkic languages|Turkic]] and [[Mongolic languages|Mongolic]] (or [[Para-Mongolic]]) origin has been suggested by a number of scholars including [[Gustaf John Ramstedt|Ramstedt]], Shiratori, Pulleyblank, [[Denis Sinor|Sinor]] and [[Gerhard Doerfer|Doerfer]], and was reportedly first used by the [[Xianbei]], as recorded in [[Book of Song]].<ref name = "songshu96">''Songshu'', [https://zh.wikisource.org/wiki/%E5%AE%8B%E6%9B%B8/%E5%8D%B796 vol. 96] quote: "{{lang|zh|樓喜拜曰：「處可寒。」虜言「處可寒」，宋言爾官家也。}}" translation: "Lou [the envoy of the younger brother to [[Tuyuhun|T'u-yü-hun]]] was glad. He bowed and said: "{{Transliteration|zh|Chu k'o han}} {{lang|zh|處可寒}}". The barbarian words ch'u k'o han mean in the language of [[Liu Song dynasty|Song]], 'Be it so, sire ({{lang|zh|爾官家}})'." by Pulleyblank, E. G. (1962) "The consonantal system of Old Chinese. Part II" [https://www2.ihp.sinica.edu.tw/file/1114AUnNESH.pdf pdf], ''Asia Major'' 9; p. 261 of 206‒65.</ref> While Sinor believes ''qaγan'' or ''qapγan'' is an intensification of ''qan'' just as ''qap-qara'' is an intensification of ''qara'' "black", in Turkic (with the eventual loss of the ''p''), Shiratori rejects a Turkic etymology, instead supporting a Mongolic origin for both ''qan'' and the female form ''qatun''.<ref>{{Cite journal|last=Shiratori|first=Kurakichi|date=1926|title=On the Titles KHAN and KAGHAN|journal=Proceedings of the Imperial Academy|language=en|volume=2|issue=6|pages=241–244|doi=10.2183/pjab1912.2.241|issn=0369-9846|doi-access=free}}</ref><ref>{{Cite journal|last=KRADER|first=LAWRENCE|date=1955|title=QAN-QAγAN AND THE BEGINNINGS OF MONGOL KINGSHIP|journal=Central Asiatic Journal|volume=1|issue=1|pages=17–35|issn=0008-9192|jstor=41926298}}</ref>

According to Vovin, the word ''*qa-qan'' "great-qan" (''*qa-'' for "great" or "supreme") is of non-Altaic origin, but instead linked to [[Yeniseian languages|Yeniseian]] ''*qεʔ ~ qaʔ'' "big, great". The origin of ''qan'' itself is harder according to Vovin. He says that the origin for the word ''qan'' is not found in any reconstructed proto-language and was used widely by Turkic, Mongolic, Chinese and Korean people with variations from ''kan, qan, han and hwan.'' A relation exists possibly to the Yeniseian words ''*qʌ:j'' or ''*χʌ:j'' meaning "ruler".

It may be impossible to prove the ultimate origin of the title, but Vovin says: "Thus, it seems to be quite likely that the ultimate source of both ''qaγan'' and ''qan'' can be traced back to Xiong-nu and Yeniseian".<ref name=Vovin_2007 />

Dybo (2007) suggests that the ultimate etymological root of Khagan comes from the Middle [[Iranian languages|Iranian]] *''hva-kama-'' ‘self-ruler, emperor’, following the view of Benveniste 1966. Savelyev and Jeong 2020 note that both the etymological root for Khagan and its female equivalent [[Khatun]] may be derived from [[Eastern Iranian languages]], specifically from "Early [[Saka language|Saka]] *''hvatuñ'', cf. the attested Soghdian words ''xwt'w'' ‘ruler’ (< *''hva-tāvya-'') and ''xwt'yn'' ‘wife of the ruler’ (< *''hva-tāvyani'')".<ref>{{Cite journal |last1=Savelyev |first1=Alexander |last2=Jeong |first2=Choongwon |date=2020 |title=Early nomads of the Eastern Steppe and their tentative connections in the West |journal=Evolutionary Human Sciences |language=en |volume=2 |pages=e20 |doi=10.1017/ehs.2020.18 |pmid=35663512 |pmc=7612788 |hdl=21.11116/0000-0007-772B-4 |s2cid=218935871 |issn=2513-843X |quote=but their ultimate origins may lie outside the Turkic family, as is most likely the case for the title of khagan (χαγάνος, chaganus) < ? Middle Iranian *hva-kama- ‘self-ruler, emperor’ (Dybo, Reference Dybo2007: 119–120). Following Benveniste (Reference Benveniste1966), Dybo (Reference Dybo2007: 106–107) considers Turkic *χatun ‘king's wife’ a word of ultimate Eastern Iranian origin, borrowed presumably from Early Saka *hvatuñ, cf. the attested Soghdian words xwt'w ‘ruler’ (< *hva-tāvya-) and xwt'yn ‘wife of the ruler’ (< *hva-tāvyani).}}</ref>

==History==
The title was first seen in a speech between 283 and 289, when the [[Xianbei]] chief [[Tuyuhun]] tried to escape from his younger stepbrother [[Murong Hui]], and began his route from the [[Liaodong Peninsula]] to the areas of [[Ordos Desert]]. In the speech one of Murong's generals, Yinalou, addressed him as ''kehan'' ({{lang-zh|c=可寒}}, later {{lang-zh|c=可汗}}); some sources suggests that Tuyuhun might also have used the title after settling at [[Qinghai Lake]] in the 3rd century.<ref name = "songshu96"/><ref>Zhou 1985, pp. 3–6</ref>

The [[Rouran Khaganate]] (330–555) was the first people to use the titles Khagan and Khan for their emperors, replacing the [[Chanyu]] of the [[Xiongnu]], whom Grousset and others assume to be [[Turkic peoples|Turkic]].<ref>Grousset (1970), pp. 61, 585, n. 92.</ref> The Rourans were stated to be descendants of the [[Donghu people]],<ref>[[Wei Shou]].

The [[Avar Khaganate]] (567–804), who may have included Rouran elements after the [[Göktürks]] crushed the Rouran ruling Mongolia, also used this title. The [[Pannonian Avars|Avars]] invaded [[Europe]], and for over a century ruled the Carpathian region. Westerners Latinized the title "Khagan" into "Gaganus" (in [[Historia Francorum]]), "Cagan" (in the [[Annales Fuldenses]]), or "Cacano" (in the [[Historia Langobardorum]]).

''[[The Secret History of the Mongols]]'', written for that very dynasty, clearly distinguishes ''Khagan'' and ''Khan'': only [[Genghis Khan]] and his ruling descendants are called ''Khagan'', while other rulers are referred to as ''Khan''.{{citation needed|date=January 2020}} The title "Khagan" or "Khaan" most literally translates to "great/supreme ruler" in the Mongol language, and by extension "sovereign", "monarch", "high king", or "emperor". The title can also be expanded with the addition of "Yekhe" (meaning "great" or "grand") to produce "Yekhe Khagan", meaning "Great Emperor".{{citation needed|date=August 2022}}

The Mongol Empire began to [[Division of the Mongol Empire|split politically]] with the [[Toluid Civil War]] during 1260–1264 and the death of [[Kublai Khan]] in 1294, but the term ''Ikh Khagan'' (Great Khan, or Emperor) was still used by the [[List of emperors of the Yuan dynasty|emperors of the Yuan dynasty]] (1271–1368), who also took on the title of the [[Emperor of China]]. After the fall of the Yuan dynasty, the title continued to be used by monarchs of the [[Northern Yuan|Northern Yuan dynasty]].<ref>H. Howorth. ''History of The Mongols'', Volume 1; [[Rene Grousset]]. ''The Empire of Steppes''; D. Pokotilov. ''History of the Eastern Mongols during the Ming Dynasty from 1368 to 1631''</ref>

Thus, the Yuan is sometimes referred to as the ''Empire of the Great Khan'', coexisting with the other independent Mongol-ruled khanates in the west, including the [[Chagatai Khanate]] and [[Golden Horde]]. Only the [[Ilkhanate]] truly recognized the Yuan's overlordship as allies (although it was effectively autonomous). Because Kublai founded the Yuan, the members of the other branches of the [[Borjigin]] could take part in the election of a new Khagan as the supporters of one or other of the contestants, but they could not enter the contest as candidates themselves.<ref>Ed. Herbert Franke, Denis Twitchett, John King Fairbank. ''The Cambridge History of China: Alien regimes and border states, 907–1368'', p. 493.</ref>

Later,{{efn|Beginning in the last years (1304) of [[Temür Khan]], grandson of Kublai; most medieval historians such as Rashid al-Din and Alugh Beg Mirza described him as Grand khaan. See: Universal history and The Shajrat ul Atrak}} Yuan emperors made peace with the three western khanates of the Mongol Empire and were considered as their nominal suzerain.<ref>''The Mongol Empire and Its Legacy'', p. 14.</ref> The nominal supremacy, while based on nothing like the same foundations as that of the earlier khagans (such as the continued border clashes among them), did last for a few decades, until the Yuan dynasty collapsed in 1368.{{efn|During this period the Mongol emperors of the Yuan held the (nominal) title of Great Khan of all Mongol Khanates (of the Mongol Empire), of which the three western Mongol khanates still showed their respect in several cases. For example, the Ilkhans' coins carried the Khagan's name up until the early 14th century. It was also once said that Khagan is "the blessing of the creator" at the court of the Golden Horde during the reign of [[Ozbek Khan]] (1313–41).}}

After the breakdown of Mongol Empire and the fall of the Yuan dynasty in the mid-14th century, the Mongols turned into a political turmoil. [[Dayan Khan]] (1464–1517/1543) once revived the Emperor's authority and recovered its reputation on the [[Mongolian Plateau]], but with the distribution of his empire among his sons and relatives as fiefs it again caused decentralized rule. The last Khagan of the [[Chahars]], [[Ligdan Khan]], died in 1634 while fighting the [[Jurchen people|Jurchen]]-led [[Later Jin (1616–1636)|Later Jin dynasty]]. In contemporary [[Mongolian language]] the words "Khaan" and "Khan" have different meanings, while [[English language]] usually does not differentiate between them. The title is also used as a generic term for a king or emperor (as {{lang|mn-Cyrl|эзэн хаан}}, {{Transliteration|mn|ezen khaan}}), as in "{{lang|mn-Cyrl|Испанийн хаан Хуан Карлос}}" ({{Transliteration|mn|Ispaniin khaan Khuan Karlos}}, "king/khaan of Spain Juan Carlos").{{citation needed|date=August 2022}}

The early khagans of the [[Mongol Empire]] were:
# [[Genghis Khan]] (1206–1227; 21 years)
# [[Ögedei Khan]] (1229–1241; 12 years)
# [[Güyük Khan]] (1246–1248; 2 years)
# [[Möngke Khan]] (1251–1259; 8 years)

== Among Turkic peoples ==
{{see also|Göktürk family tree}}
The title became associated with the [[Ashina tribe|Ashina]] ruling clan of the [[Göktürks]] and their dynastic successors among such peoples as the [[Khazars]] (cf. the compound military title [[Khagan Bek]]). Minor rulers were rather relegated to the lower title of khan.

Both Khagan as such and the [[Turkish language|Turkish]] form Hakan, with the specification in [[Arabic language|Arabic]] ''al-Barrayn wa al-Bahrayn'' (meaning literally "of both lands and both seas"), or rather fully in [[Ottoman Turkish language|Ottoman Turkish]] ''Hakan ül-Berreyn vel-Bahreyn'', were among the titles in the official full style of the Great Sultan (and later Caliph) of the [[Ottoman Empire]], reflecting the historical legitimation of the dynasty's rule as political successor to various conquered (often Islamised) states. (The title began: Sultan Hân N.N., [[Padishah]], ''Hünkar'', Sovereign of the House of Osman, [[Sultan of Sultans]], Khan of Khans, Commander of the Faithful and Successor of the Prophet of the Lord of the Universe; next followed a series of specifically "regional" titles, starting with Protector of the Holy Cities of Mecca, Medina and Jerusalem.)

"Khagan" is the second title of [[Safavid dynasty|Safavid]] and [[Qajar dynasty|Qajar]] shahs (kings) of Iran. For example, Agha Muhammad Khan Qajar, Fath Ali Shah and other Qajar shahs used this title. The nickname of Shah Ismail and other Safavid shahs is ''Kagan-i Suleyman shan'' (Khagan with the glory of Solomon).

All of this implied Kirghiz subordination to Tang authority, at least in Chinese eyes. According to the letter, Kirghiz tribute had come to the Tang court "uninterruptedly" until the end of the Tianbao reign period (742&ndash;756) when Kirghiz contact with the Tang state was cut off by the rise of Uighur power in Mongolia. |url = https://books.google.com/books?id=NB6DEdAxLOsC&q=li+ling+kirghiz&pg=PA126 |version = illustrated |volume = 13 |via = Brill's Inner Asian library |year=2005 |publisher = Brill |isbn = 978-90-04-14129-2 |page = 126 }}</ref> The [[Tang dynasty]] Chinese emperors were recognized as khagans of the Turks at least from 665 to 705; moreover, two appeal letters from the Turkic hybrid rulers, Ashina Qutluγ Ton Tardu in 727, the Yabgu of [[Tokharistan]], and Yina Tudun Qule in 741, the king of [[Tashkent]], addressing [[Emperor Xuanzong of Tang]] as '''Tian Kehan''' during the [[Umayyad]] expansion.<ref>Bai, p.&nbsp;230.</ref><ref>Xue, pp.&nbsp;674&ndash;675.</ref>

{{Main|Rus' Khaganate}}

In the early 10th century, the [[Rus' people]] employed the title of ''kagan'' (or ''qaghan''), reported by the Persian geographer [[Ahmad ibn Rustah]], who wrote between 903 and 913.<!--see notes on FA review and talk page [[Talk:Rus' Khaganate]]-->

It is believed that the tradition endured in the eleventh century, as the [[metropolitan bishop]] of [[Kiev]] in the [[Kievan Rus']], [[Hilarion of Kiev]], calls both [[grand prince]] [[Vladimir I of Kiev]] (978–1015) and grand prince [[Yaroslav the Wise]] (1019–1054) by the title of ''kagan'', while a [[Graffito (archaeology)|graffito]] on the walls of [[Saint Sophia's Cathedral, Kiev|Saint Sophia's Cathedral]] gives the same title to the son of Iaroslav, grand prince [[Sviatoslav II of Kiev]] (1073–1076).
