Ivan IV was succeeded by his son Feodor, who was uninterested in ruling and possibly mentally deficient. Actual power went to Feodor's brother-in-law, the boyar Boris Godunov (who is credited with abolishing Yuri's Day, the only time of the year when serfs were free to move from one landowner to another).
