Life

Mikhail is sometimes said to have been the first prince of Moscow. Two chronicles refer to him as "Mikhail of Moscow", but Daniel, the youngest son of Aleksandr Nevsky, is usually considered to be the first prince of Moscow. His nickname, Khorobrit, is derived from the Old Russian word khorobrovati.
In 1248, he seized the town of Vladimir and expelled his uncle Sviatoslav Vsevolodovich, who fled to Yuryev-Polsky. Mikhail was killed fighting Tautvilas and Gedivydas, the nephews of the Lithuanian ruler Mindaugas, at the battle of Protva on 15 January 1248. On Mikhail's death, if it is assumed that an appanage principality was created, Moscow reverted as an escheat to the grand prince. His brother Andrey was confirmed as grand prince by the khan of the Golden Horde.
