Tribhuwan Bir Bikram Shah.(त्रिभुवन वीर विक्रम शाह), (June 23, 1906 – March 13, 1955) was King of Nepal from 11 December 1911 until his death (not considering his exile from 7 November 1950 to 18 February 1951). Born in Kathmandu, the capital city of Nepal, he ascended to the throne at the age of five, upon the death of his father, King Prithvi Bir Bikram Shah, and crowned on 20 February 1913 at the Nasal Chowk, Hanuman Dhoka Palace in Kathmandu, with his mother acting as regent. At the time, however, the position of monarch was mainly titular, with real power in the country residing in the powerful, conservative Rana family, which supplied the country with its hereditary prime minister. The Rana period is known for the tyranny, debauchery, economic exploitation and religious persecution by the rulers.
