A series of princes briefly reigned in Kiev thereafter, with Andrey usually managing to put his preferred candidates on its throne, until his brother Vsevolod "the Big Nest" was driven out by the Rostislavichi of Smolensk in April 1172, enthroning Rurik Rostislavich. Andrey was most displeased when he heard about this, and assembled another coalition army under his son Yury to militarily enforce his will on Kiev.

Immediately, his surviving step-brothers, son and nephews started fighting amongst themselves about who had the right to succeed him. The conflict would not be resolved until Vsevolod Yurievich "the Big Nest" had defeated his other brothers and his nephews, and seized power across Suzdalia in 1177.
