Rogvolod Borisovich
Rogvolod, baptised Vasily and also called Rogvolod Borisovich (c. 1110 – after 1171), was the son of Rogvolod-Boris Vseslavich of the Drutsk line. He may have first received Drutsk in 1127, shared his family's exile to Byzantium after 1129, and returned in 1140.
He held Polotsk in 1144–1151 until the townsmen handed him to Rostislav of Minsk, regained Drutsk in 1158 and Polotsk in 1159, but lost the city after his defeat at Gorodets in 1162. The Rogvolod Stone of 1171 near Orsha preserves his name, and his son Gleb later ruled Drutsk.
