[[File:Family Tree of The Kings of Siam.png|thumb|upright|The family tree of Thai monarchs]]

The succession of [[Monarchy of Thailand|Thai monarchs]] began with [[Si Inthrathit]] at the establishment of the [[Sukhothai Kingdom|first Thai kingdom]] in 1238. With brief interruptions, 55 [[Monarch|monarchs]] and 27 [[Front Palace|viceroys]] have ruled over four successive kingdoms, the current monarch being [[Vajiralongkorn]] (Rama X) of the [[Chakri dynasty]].

==Titles and naming conventions==
{{further|Thai royal ranks and titles}}
In the [[Sukhothai Kingdom]], the monarch used the title ''Khun'' ({{langx|th|ขุน}}) or ''Phaya'' ({{langx|th|พญา}}), while ''Pho Khun/ Phaya'' ({{langx|th|พ่อขุน/ พ่อพญา}}) or ''Phoo Khun/ Phaya'' ({{langx|th|ปู่ขุน/ ปู่พญา}}) were used to refer to deceased monarchs or senior relatives who were monarchs.<ref>{{cite web|author=<!-- not stated --> |date= 2023|title=“พ่อขุน” ไม่เคยใช้เรียกกษัตริย์ที่ครองราชย์อยู่ “รามคำแหง” พระนามที่ชวนฉงน|url= https://www.silpa-mag.com/history/article_44228|website=Silpa-mag.com |location=|publisher=Silpawattanatham|access-date=}}</ref>

In the [[Ayutthaya Kingdom]] and afterward, ''[[Thai royal ranks and titles|thanandon]]'', the system of Thai royal titles, determines the style of the monarch's full [[regnal name]] (which includes the title), consisting of two interconnected parts:

* The first part is the title ''Phra Bat Somdet Phra Chao Yu Hua'' ({{langx|th|พระบาทสมเด็จพระเจ้าอยู่หัว}}, 'His Majesty the King'). The title is split by the regnal name, written between ''Phra'' and ''Chao''. If the monarch was not formally [[Coronation of the Thai monarch|crowned]], ''Phra Bat'' is omitted. If the monarch ruled as a [[Tributary state|tributary]] or was [[Usurper|usurped]], ''Somdet'' may be omitted.
** Sometimes, ''Chao Yu Hua'' is fully omitted. Other times, only ''Yu Hua'' is omitted, in which case ''Chao'' follows the remaining components of the title and precedes the regnal name.
* The second part is the regnal name, of which only a portion may be used to commonly refer to the monarch. It may differ from their birth name, their name as ''[[uparaja]]'' ([[viceroy]]), or their [[posthumous name]] and/or historical style. This list refers to monarchs by the names most often used by traditional historians.<ref name=":2">{{Cite journal |last=Jones |first=Robert B. |date=June 1971 |title=Thai titles and ranks; including a translation of Traditions of royal lineage in Siam by King Chulalongkorn |url=https://hdl.handle.net/1813/57549 |journal=Southeast Asia Program Data Papers Series |hdl=1813/57549 |via=Cornell University}}</ref>

[[Western nations]] referred to the monarch as the "King of Siam" ({{langx|la|Rex Siamensium}}), regardless of Thai titles, since the initiation of relations in the 16th century. [[Mongkut|Mongkut (Rama IV)]] was the first monarch to adopt the title when the name ''Siam'' was [[Bowring Treaty|first used in an international treaty]].<ref>{{cite web|title="สยาม" ถูกใช้เรียกชื่อประเทศเป็นทางการสมัยรัชกาลที่ 4|url=https://www.silpa-mag.com/club/art-and-culture/article_10496|publisher=ศิลปวัฒนธรรม|date=6 July 2017|access-date=10 August 2017|language=th}}</ref> When the kingdom's name was changed to Thailand, the monarch's Western title changed accordingly.<ref>{{Cite web |title=Siam definition and meaning |url=https://www.collinsdictionary.com/dictionary/english/siam |access-date=11 January 2020 |website=[[Collins English Dictionary]]}}</ref>

== Regarding the relationship between kings and viceroys ==
In Siam, the relationship between the king and the viceroy (called the [[Uparaja#Siam (Thailand)|Uparaja]]) was based on shared rule but clear hierarchy. The king was the highest ruler, while the viceroy was usually a close relative chosen to help govern and serve as the likely successor, though this would often prove false due to other member of the family starting a succession war. The viceroy had real authority, controlling parts of the kingdom and managing government and military affairs when needed. However, all power officially came from the king, and the viceroy was expected to support and follow the monarch’s decisions. Because the viceroy had his own court and influence, this system sometimes led to rivalry or competition between the two. The position continued for many centuries until King [[Chulalongkorn]] abolished it in the late 19th century to centralize power under the monarchy. While the viceroy is not the king, through out the history of Siam, there were moments where these viceroys were crowned "in equal power" as the monarch such that of the coronation of [[Mongkut|Rama IV]] and [[Pinklao]].

===Phra Ruang dynasty (1238–1438; 1468–1474)===
The Phra Ruang dynasty was the only royal lineage that ruled over the [[Sukhothai Kingdom]], the first Central Thai state. Established by [[Si Inthrathit]] in 1238, who declared independence from the Khmer Empire, the dynasty laid the foundations for Thai society.<ref name="Coedes1921">{{cite journal | last = Cœdès | first = Georges | author-link = Georges Coedès | year = 1921 | title = The Origins of the Sukhodaya Dynasty | journal = Journal of the Siam Society | volume = 14 | issue = 1 | pages =  | publisher = Siam Heritage Trust | url = http://www.siamese-heritage.org/jsspdf/1921/JSS_014_1b_Coedes_OriginsOfSukhodayaDynasty.pdf | access-date = 17 March 2013 | quote = The translation of this paper, which has been read at a joint session of the [[Royal Asiatic Society of Great Britain and Ireland]], [[Société Asiatique]], and [[American Oriental Society]], and published in the ''Journal asiatique'' (April–June 1920), is the work of Mr. J.

The dynasty is named after the ''Traiphum Phra Ruang'', a [[Buddhist cosmology]] book written by [[Maha Thammaracha I]]. During his reign, the kingdom was invaded by [[Ayutthaya Kingdom|Ayutthaya]], a neighboring Thai state, becoming a [[tributary state|tributary]] during the reign of [[Maha Thammaracha II]].<ref name="CoedesBook" />{{rp|222}}

In the Sukhothai Kingdom, the monarch ruled from the city of [[Sukhothai (city)|Sukhothai]], while the [[heir presumptive]] would occasionally be named [[uparaja]], or [[viceroy]], and ruled in [[Si Satchanalai]]. In 1438, Ayutthaya annexed Sukhothai at the death of [[Maha Thammaracha IV]] when [[Borommarachathirat II]] of Ayutthaya named his son [[Borommatrailokkanat|Prince Ramesuan]] uparaja. In Ayutthaya, the tradition would evolve into the [[Front Palace]] system.<ref name=":1">{{Cite book |author=David K.

[[File:Administrative Division of Ayutthaya Kingdom in 1468.jpg|thumb|160px|Ayutthaya Kingdom in 1468]]
The Ayutthaya Kingdom was a result of a unification between two states: the Kingdom of Suphannaphum (Suphanburi) and the Kingdom of Lavo. Though the Kingdom of Lavo was originally a Mon kingdom, the migration of the Tai peoples into the Chao Phraya basin replaced the original Mons, consequently becoming the governors of these regions. This resulted in the capital moving from Lavapura (Lopburi) and Suphannaphum (Suphanburi) to Ayodhya (Old Ayutthaya), a new capital.<ref>{{Cite web |title=History of Ayutthaya - Temples & Ruins - Wat Ayodhya |url=https://www.ayutthaya-history.com/Temples_Ruins_Ayodhya.html |access-date=2024-07-06 |website=www.ayutthaya-history.com}}</ref> Later on, the Kingdom of Nakhon si Thammarat came under the influence of Ayutthaya after seceding from Sukhothai, and Sukhothai losing influence and coming under Ayutthayan influence.

This conflict would last long into the history of Ayutthaya Kingdom, where families from the four major regional kingdoms vie over the throne of the kingdom. These kingdoms are: Kingdom of Nakhon Si Thammarat, Kingdom of Sukhothai, Kingdom of Lavo, and Kingdom of Suphannaphum. The Kingdom of Sukhothai was integrated into the Kingdom of Ayutthaya along with its noble families.<ref>{{Cite book |url=http://archive.org/details/royalchronicleso0000unse |title=The royal chronicles of Ayutthaya |date=2000 |publisher=Bangkok : The Siam Society |others=Internet Archive |isbn=978-974-8298-48-1}}</ref>

As previously mentioned, the kingdom of Ayutthaya was the result of the unification between two federations: Lavo and Suphannaphum. The ruling dynasty of Lavo gave rise to the Uthong Dynasty, in which the Suphannaphum dynasty came from the [[Suphannabhum|Suphannaphum federation]]. This federation held significant influence within the kingdom leading them to take control of the throne in 1310.
