Bhutan, officially the Kingdom of Bhutan, is a landlocked country in South Asia located at the eastern end of the Himalayas. It is bordered to the north by China and to the south, east and west by India. To the west, it is separated from Nepal by the Indian state of Sikkim, while further south it is separated from Bangladesh by the Indian states of Assam and West Bengal. Bhutan’s capital and largest city is Thimphu.
Bhutan existed as a patchwork of minor warring fiefdoms until the early 17th century, when the lama and military leader Zhabdrung Ngawang Namgyal, fleeing religious persecution in Tibet, unified the area and cultivated a distinct Bhutanese identity. Later, in the early 20th century, Bhutan came into contact with the British Empire and retained strong bilateral relations with India upon its independence.
Bhutan is located on the southern slopes of the eastern Himalayas, landlocked between the Tibet Autonomous Region to the north and the Indian states of Sikkim, West Bengal, Assam and Arunachal Pradesh to the west and south. It lies between latitudes 26°N and 29°N, and longitudes 88°E and 93°E. The land consists mostly of steep and high mountains crisscrossed by a network of swift rivers, which form deep valleys before draining into the Indian plains. Elevation rises from 200 m (660 ft) in the southern foothills to more than 7,000 m (23,000 ft). This great geographical diversity combined with equally diverse climate conditions contributes to Bhutan’s outstanding range of biodiversity and ecosystems.
