Last but not least, the Ural Cossacks. According to Wikipedia: The Ural Cossack Host was a cossack host formed from the Ural Cossacks -- those cossacks settled by the Ural River. Their alternative name, Yaik Cossacks, comes from the old name of the river. History A group of Orenburg cossacks (1912), descendants of Yaik Cossacks from Sakmara settlement, founded by Yaik Cossacks before the foundation of Orenburg.The Yaik (Ural) Cossacks although speaking Russian and identifying themselves as being of primarily Russian ancestry also incorporated many Tatars into their ranks. According 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. These Tatars might be both Chuvash people and Mishari (Meschera in Russian, Miser in Tatar language), the latter had not only Moslems and Jews, but Christians among them to facilitate their merge with Russians[4.
