The first official All-USSR koresh championship took place in Kazan in 1928 and was followed by the first TASSR (Tatar Autonomous Soviet Socialist Republic) national championship in
1949. Since 1956, regular Tatar Köräs competitions have been organised in honor of the national hero and poet Musa Cälil.
At the turn of 1950 and 1960, the Soviet Federation of freestyle wrestling, Greco-Roman wrestling, and sambo started to develop Tatar Köräs. Sportsmen from the neighbour regions, such as Bashkortostan, Mordovia, and Ulyanovsk City came to compete in Kazan for the first time in 1959. In 1960, the capital of Tatarstan was appointed host of the first RSFSR (Russian Soviet Federative Socialist Republic) national koresh championship, an event that has been repeated every year since that date. It was organised in Kazan about 15 times, but also in other cities, such as Salavat, Orenburg, Oktyabrsky, Tuymazy, Chelyabinsk, Cheboksary, Almetievsk, Samara, Ulyanovsk, Naberezhnye Chelny. Sportsmen from 36 Russian regions have participated in the Russian championships over the past years.
