Vasilko Konstantinovich

Vasilko Konstantinovich (1208-1238), eldest son of Konstantin Vsevolodovich of Vladimir, ruled Rostov from his father's death in 1218. He reached the Kalka battle in 1223 too late to fight.

In 1238 he faced Batu's Mongol invasion, was captured after the rout on the Sit River and killed in the Sherensky forest. His sons Boris and Gleb divided Rostov and Beloozero; the Orthodox Church venerates him as a martyr.
