In 1149 Prince Yuri Dolgoruky of Suzdal banished Iziaslav Mstyslavych from Kyiv but in 1151 Iziaslav again became the Grand Prince of Kyiv after his bloodless victory over the army of Yuri Dolgoruky and reigned together with his uncle Vyacheslav Volodymyrovych to the end of his life. In 1147 Prince Iziaslav severed church ties with Constantinople and appointed Klyment Smoliatych (a Rus) the Metropolitan of Kyiv. The problem of strengthening the independence of the Rus Orthodox Church was focal in his internal policy. In foreign policy, Iziaslav Mstyslavych directed his attention to European countries – Hungary, Bohemia, and Poland and consolidated union with their rulers by dynastic marriages. His life is described in a chronicle made by the boyar Petro Boryslavych, which partly survived in the Hypatian codex.
