The Wangchuck dynasty (Tibetan: དབང་ཕྱུག་རྒྱལ་རྒྱུད་, Wylie: Dbang-phyug Rgyal-rgyud) is the ruling family of Bhutan, having held the hereditary position of Druk Gyalpo ("Dragon King") since 1907. Prior to reunification, the Wangchuck family had governed the district of Trongsa as descendants of Dungkar Choji. They eventually overpowered other regional lords and earned the favour of the British Empire. After consolidating power, the 12th Penlop of Trongsa Gongsar Ugyen Wangchuck was elected Druk Gyalpo, thus founding the dynasty. The position of Druk Gyalpo – who heads the royal family of Bhutan – is more commonly known in English as the King of Bhutan, however "Druk Gyalpo" would be translated literally as "Dragon King" (or less commonly, "King of the Dragons", or "Thunder Dragon King")
The Wangchuck dynasty ruled government power in Bhutan and established relations with the British Empire and India under its first two monarchs. The third, fourth, and fifth (current) monarchs have put the kingdom on its path toward democratization, decentralization, and development.
