Following the fragmentation of the Kievan Rus polity, the Principality of Kiev emerged. Subsequent years saw rivalries of the competing princes of the dynasty and the weakening of Kiev's political influence, although the city temporarily prevailed after the defeat of Polotsk at the Battle on the river Nemiga (1067) that also led to the burning of Minsk. In 1146 the next Ruthenian bishop, Kliment Smoliatich of Smolensk, was appointed to serve as the Metropolitan of Kiev and all Rus'. In 1169 Andrei of Suzdal (Bogolyubsky) sent an army against Mstislav II Izyaslavich and Kiev. Led by one of his sons, it consisted of the forces of eleven other princes, representing three of the main branches of the Rurikid dynasty against the fourth, the Iziaslavichi of Volynia. The allies were victorious, and sacked the city for three days. They left the old town and the prince's hall in ruins, and took many pieces of religious artwork - including the "Theotokos of Vladimir" icon - from nearby Vyshhorod. Bogolyubsky established a new capital at Vladimir. Although he lost Kiev five years later, the prestige from this conquest of the city allowed the Principality of Vladimir-Suzdal to take a leading role as the predecessor of the modern Russian state.
