Jigme Singye Wangchuck is a member of the House of Wangchuck who was the king of Bhutan from 1972 until his abdication in 2006. During his reign, he advocated the use of a Gross National Happiness index to measure the well-being of citizens rather than Gross domestic product.

The Wangchuck dynasty have held the hereditary position of Druk Gyalpo 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"
