In OTL Tannu Tuva was established by a combination of the Bolshevik troops taking control of Tuva, and the Tuvans declaring independence from Russia (having been acquired from China). The entity created in August 1921 was called Tannu Tuva until 1926, and was absorbed into the USSR in 1944, and is now known as Tyva Republic within the Russian Federation. Its capital Kyzyl was the most remote in the world (title now held by Ulan Bator), and the state was most notable for its stamps, of which several were diamond-shaped and triangular, and all being produced in Moscow. It was the third persisting Communist state - after its neighbours, the USSR, and Mongolia.
