Briachislav Vasilkovich

Briachislav Vasilkovich (died after 1241) was a Vitebsk-line prince who ruled Vitebsk from about 1221 and Polotsk from about 1232, probably a son of Vasilko Bryacheslavich and a daughter of Davyd of Smolensk.

Tradition credits him with founding three churches in Polotsk in 1203, dedicated to Holy Wisdom, Saints Boris and Gleb, and Paraskeva Pyatnitsa. In 1239 the chronicles show the future Alexander Nevsky marrying his daughter at Polotsk. He was still ruling Polotsk after 1241.
