Bhutan

constitutional monarchy

After Britain’s victory in the 1865 Duar War, Britain and Bhutan signed the Treaty of Sinchulu, under which Bhutan would receive an annual subsidy in exchange for ceding land to British India. Ugyen WANGCHUCK -- who had served as the de facto ruler of an increasingly unified Bhutan and had improved relations with the British toward the end of the 19th century -- was named king in 1907. Three years later, a treaty was signed whereby the British agreed not to interfere in Bhutanese internal affairs, and Bhutan allowed Britain to direct its foreign affairs.
