Chakri Dynasty Family Tree - The Royal House of Thailand

The Chakri dynasty is the ruling royal house of Thailand, founded in 1782 by King Rama I (Buddha Yodfa Chulaloke) and continuing through ten monarchs to the reigning king, Rama X (Vajiralongkorn). For nearly two and a half centuries it has presided over Siam's transformation from an early modern Southeast Asian kingdom into the modern nation of Thailand, surviving colonial pressure, foreign war, and the 1932 shift from absolute to constitutional monarchy. ## Origins The dynasty takes its name from its founder's pre-royal title, Chao Phraya Chakri, the highest military rank in the old Siamese order. After serving as a general under King Taksin of Thonburi, he took the throne amid the political turmoil that followed Taksin's downfall, founded Bangkok as the new capital in 1782, and set about restoring the laws, religious texts, and administrative structures that had been lost when Ayutthaya fell to Burma in 1767. His descendants ruled in direct succession from father to son or brother to brother, with several kings, notably Rama III, having no direct heir positioned to inherit and the throne instead passing sideways to a brother or nephew. ## Notable members Several Chakri kings are individually significant. Rama IV (Mongkut) spent nearly three decades as a Buddhist monk before opening Siam to Western trade and diplomacy. His son Rama V (Chulalongkorn) abolished slavery and modernized the kingdom's administration while keeping it the only Southeast Asian state never colonized by a European power. Rama VII (Prajadhipok) presided over the end of absolute monarchy in 1932 and abdicated in 1935. Rama IX (Bhumibol Adulyadej), who reigned for seventy years until 2016, became the longest-reigning monarch in Thai history, and his children include the current king, Rama X, and the widely respected Princess Sirindhorn. ## Significance The Chakri dynasty is unique among Southeast Asian royal houses for its continuous, unbroken rule and its central role in preserving Thai national identity and independence through the colonial era. Its monarchs remain constitutionally central to Thai public life today, with the king serving as head of state and a unifying symbol above elected politics. | Fact | Details | |---|---| | Founded | 1782, by Rama I | | Current monarch | Rama X (Vajiralongkorn), since 2016 | | Capital established | Bangkok | | Number of kings to date | Ten | | Longest reign | Rama IX (Bhumibol Adulyadej), 1946-2016 | | Country | Thailand (formerly Siam) |
