Tuvan People's Republic, formerly Tannu Tuva, is annexed by the U.S.S.R.
The Tuvan People's Republic (TPR; Tuvan: Тыва Арат Республик, romanized: Tywa Arat Respublik; Yanalif: Tьʙа Arat Respuʙlik, IPA: [tʰɯˈʋa aˈɾatʰ resˈpʰuplik]), known as the Tannu Tuva People's Republic until 1926, was a partially recognized socialist republic that existed between 1921 and 1944. The country was located in the same territory as the former Tuvan protectorate of Imperial Russia, known as Uryankhay Krai, north-west of Mongolia, and now corresponds to the Tuva Republic within the Russian Federation.
The Soviet Union and Mongolia were the only countries to formally recognize it during its existence, in 1924 and 1926 respectively. After a period of increased Soviet influence, in October 1944, the polity was absorbed into the Russian SFSR (the largest constituent republic of the Soviet Union) at the request of the Tuvan parliament, ending twenty-three years of independence.
