The Wangchuck dynasty () have held the hereditary position of Druk Gyalpo ("Dragon King") of Bhutan 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. There have been five Wangchuck kings of Bhutan, namely: Ugyen Wangchuck (b.1861–d.1926) "First King"; reigned 17 December 1907 – 21 August 1926. Jigme Wangchuck (b.1905–d.1952) "Second King"; r. 21 August 1926 – 24 March 1952. Jigme Dorji Wangchuck (b.1929–d.1972) "Third King"; r. 24 March 1952 – 24 July 1972. Jigme Singye Wangchuck (b.1955) "Fourth King"; r. 24 July 1972 – 9 December 2006. Jigme Khesar Namgyel Wangchuck (b.1980) "Fifth King"; r. 9 December 2006 – present. The ascendency of the Wangchuck family is deeply rooted in the historical politics of Bhutan. Between 1616 and 1907, varying administrative, religious, and regional powers vied for control within Bhutan. During this period, factions were influenced and supported by Tibet and the British Empire. Ultimately, the hereditary Penlop of Trongsa, Ugyen Wangchuck, was elected the first Druk Gyalpo by an assembly of his subjects in 1907, marking the ascendency of his dynasty.
