Mstislav Mstislavich

[4] On his way to Novgorod, Mstislav delivered the key town of Torzhok from a siege laid to it by Vsevolod III of Vladimir.

[5] In 1216, Mstislav mustered a large coalition of princes of Rus' which defeated Vladimir-Suzdal in the Battle of Lipitsa.

After that, he installed his ally Konstantin of Rostov as Grand Prince of Vladimir and married his own daughter to Yaroslav of Suzdal, who had fortified himself in Torzhok.

In 1219, he concluded peace with his chief rival, Daniel of Galicia, who thereupon married Mstislav's daughter Anna.

[8] Mstislav reigned in Galicia until 1227, when boyar intrigues constrained him to leave the city to his son-in-law, Andrew of Hungary.
