Bhutan, landlocked country of south-central Asia, located on the eastern ridges of the Himalayas. Historically a remote kingdom, Bhutan became less isolated in the second half of the 20th century, and consequently the pace of change began to accelerate. With improvements in transportation, by the early 21st century a trip from the Indian border to the Bhutanese capital, Thimphu, that once took six days by mule could be made in just a few hours by car along a winding mountain road from the border town of Phuntsholing. The governmental structure also changed radically. Reforms initiated by King Jigme Dorji Wangchuk (reigned 1952–72) in the 1950s and ’60s led to a shift away from absolute monarchy in the 1990s and toward the institution of multiparty parliamentary democracy in 2008.
