Russians in Bulgaria
Russians (Bulgarian: руснаци, rusnatsi) form the fourth largest ethnic group in Bulgaria, numbering 31,679 in 2019, and mostly living in the large urban centres, such as Sofia, Plovdiv, Varna and Burgas. Although the largest wave of Russian settlers (White Guards) arrived following the events surrounding the October Revolution and the Russian Civil War, compact groups of Russians had been living in Bulgaria for centuries before that.
