>During the 1870s, power struggles between the rival valleys of Paro and Tongsa led to civil war in Bhutan, eventually leading to the ascendancy of Ugyen Wangchuck, the ponlop (governor) of Tongsa. From his power base in central Bhutan, Ugyen Wangchuck defeated his political enemies and united the country following several civil wars and rebellions during 1882–85.

In the late 1980s and early 1990s, the country expelled or forced to leave nearly one-fifth of its population in the name of preserving its Tibetan Mahayana Buddhist culture and identity. The
