Prince and ruler
Michael Vsevolodovich belonged to the Olgovichi branch of the Rurikid dynasty. He served as Prince of Pereyaslavl in 1206, of Novgorod-Seversk from 1219 to 1226, and of Chernigov from 1223 to 1235 and again from 1242 to 1246. He held Novgorod in 1225–1226 and 1229–1230, Galicia in 1235–1236, and was twice Grand Prince of Kiev, in 1236–1239 and 1241–1243.
As a ruler he promoted commerce, negotiating trade treaties with Polish and Hungarian powers, and granted the Novgorodians tax relief and broader political autonomy. Sources describe him as pious and meek from childhood. He suffered from poor health that, by tradition, was relieved around 1186 through the prayers of Saint Niketas the Stylite.
Michael took part in the Battle of the Kalka River in 1223, an early clash between the princes of Rus' and the advancing Mongol forces.
