Twenty years after the conquest of the Volga from Kazan to Astrakhan, in 1577 Moscow sent troops to disperse pirates and raiders along the Volga (one of their number was Ermak). Later, as Pushkin wrote, a lot of Nogai joined Yaik Cossacks. These Tatars might be both Chuvash people and Mishari (Meschera in Russian, Mişär in Tatar language), the latter had not only Muslims and Jews, but Christians among them to facilitate their merge with Russians Meschera were important on Don as well. Īccording to Peter Rychckov some these Tatars called themselves Bulgarians of Khazar origin, and the first Yaik Cossacks, including these Tatars and Russians, existed by the end of 14th century. The Yaik (Ural) Cossacks although speaking Russian and identifying themselves as being of primarily Russian ancestry also incorporated many Tatars into their ranks.

A group of Orenburg cossacks (1912), descendants of Yaik Cossacks from Sakmara settlement, founded by Yaik Cossacks before the foundation of Orenburg.
