Son of the Grand Prince of Kyiv Vsevolod Sviatoslavych the Red. In 1210–1223 ruled near Chernihiv. Is known also as Prince Mykhailo of Chernihiv. In 1223 took part in the battle against the Mongol-Tatars at the River Kalka, later reigned in Chernihiv. In 1225 and 1229 was the Prince of Novgorod. In the 1230 s fought against Princes Danylo Romanovych of Halych, Volodymyr Riurykovych, and Yaroslav Vsevolodovych for Halych and Kyiv. In 1235 Mykhailo Vsevolodovych, with the support of King Béla IV of Hungary captured Halych and in March 1238 took the Kyivan throne for a short time (appointing his son Rostyslav to rule Halych). In 1239 (according to other information in 1238) during the Mongol-Tatar invasion left for Hungary and later for Poland where he tried to get assistance (in particular from the Pope Innocent IV) in the struggle against the Mongols. At that period his domains were usurped and divided among princes. In 1244 (or 1245) he returned to Chernihiv.
In 1246, by order of Batu Khan went to the Horde where he hoped to receive a yarlyk (patent) to rule the Chernihiv Principality.

According to other version, Mykhailo Vsevolodovych was killed for putting to death the first Mongol-Tatar envoys, which came to Kyiv in 1239.
In 1547 was canonized by the Orthodox Church as a Passion-Sufferer.
