In 1183, Mstislav participated with Svyatoslav Vsevolodovich of Kiev, Rurik Rostislavich, Galician and Pereyaslav armies on a campaign against the Polovtsi , which ended in victory on the river Oreli.

Daniel and his mother fled to Hungary, the king again went to Galich. Mstislav was expelled, and the throne was briefly occupied by the boyar Vladislav Kormilich. Almost immediately Cracow prince Leshek White organized a campaign against Galich, in which Mstislav's troops also participated.

On the death of his elder brother Ingvar (about 1220) Mstislav took the throne of the Principality of Lutsk throne, leaving Peresopnytsia behind him.
