The Druk Gyalpo is the head of state of the Kingdom of Bhutan. In the Dzongkha language, Bhutan is known as Drukyul which translates as "The Land of the Thunder Dragon". Thus, while kings of Bhutan are known as Druk Gyalpo, the Bhutanese people call themselves the Drukpa, meaning "people of Druk (Bhutan)".
