The Republic of Touva is situated in the far south of Siberia. Its capital city of Kyzyl is located near the geographic "center of Asia". The eastern part of the republic is forested and elevated, and the west is a drier lowland. On August 14, 1921 the Bolsheviks (supported by Russia) established a Tuvan People's Republic, popularly called Tannu-Tuva. In 1926, the capital (Belotsarsk; Khem-Beldyr since 1918) was renamed Kyzyl, meaning "Red"). Tuva was de jure an independent state between the World Wars. The Soviet Union annexed Tuva outright in 1944, apparently with the approval of Tuva's Little Khural (parliament), though there was no Tuva-wide vote on the issue. The exact circumstances surrounding Tannu-Tuva's incorporation into the USSR in 1944 remain obscure. Salchak Toka, the leader of Tuvan communists, was given the title of First Secretary of the Tuvan Communist Party, and became the de-facto ruler of Tuva until his death in 1973. Tuva was made the Tuvan Autonomous Oblast and then became the Tuva ASSR on October 10, 1961. The Soviet Union kept Tuva closed to the outside world for nearly fifty years. Some Tuvans, even near Kyzyl, still live in traditional yurts, round, demountable and portable dwellings with sectional lath trellis walls, decorated pole roofs and covered with white felt and canvas, with colourful cloth lining. There is a central smoke-hole above the hearth or stove. It is used to tell the time as the sunlight moves around inside the yurt. The interior is arranged with the man's side to the left, the woman's to the right of the door facing East, with the altar cupboard facing that.
