Prince of Turov. He succeeded on the death of his older brother in 1052 as Prince of Novgorod. In accordance with the terms of his father's testament, he succeeded in 1054 as IZIASLAV I Grand Prince of Kiev. It is also likely that his territories included Novgorod and Pskov. He was deposed in Kiev by a mob which, dissatisfied with his refusal to attack the Kuman [Cumans], released Vseslav Prince of Polotsk from prison and proclaimed him Grand Prince of Kiev in Sep 1068, forcing Iziaslav to flee to Poland. Iziaslav I was restored in 1069 with the help of Boleslaw II King of Poland. He was deposed again in Kiev in 1073 by his younger brother Sviatoslav, restored again in 1077 after Sviatoslav died. He answered the call from his brother Prince Vsevolod for military support against their nephew Oleg Sviatoslavich, whom they defeated 3 Oct 1078 at Nezhatin Meadow near Chernigov.
