Sudislav Vladimirovich
Sudislav Vladimirovich (died 1063), youngest son of Vladimir the Great of Kiev, ruled as prince of Pskov from 1014. In 1036 his brother Yaroslav the Wise seized him, abolished his principality and imprisoned him in Kiev for twenty-three years to secure the succession for his sons.
In 1059 his nephews freed him after he swore to renounce the throne. He became a monk at Saint George's Monastery and died there in 1063, the first Rurikid prince recorded as a monk.
