Russians (Bulgarian: руснаци, rusnatsi) form the fourth largest ethnic group in Bulgaria, numbering 9,978 according to the 2011 census,
Among the early Russian settlers were Old Believer Nekrasov Cossacks, some of which founded the village of Tataritsa in then-Ottoman-ruled Southern Dobruja (nowadays part of the village of Aydemir in Silistra Province) in 1674, building a church in 1750. Another Russian-inhabited village in the northeast of Bulgaria is Kazashko in Varna Province, where descendants of Kuban and Don Cossacks have been living since 1905. The members of these Old Believer communities are locally known as Lipovans (липованци, lipovantsi) and belong to a group also inhabiting Romania and Ukraine. Their main occupation is fishing, in the Danube for the Lipovans in Tataritsa and in Lake Varna for those in Kazashko.
