Vladimir IV Rurikovich

Vladimir IV Rurikovich (1187–1239), second son of Rurik Rostislavich of Smolensk, held Pereyaslavl from 1206 and Smolensk from 1212. He fought the Mongols on the Kalka River in 1223, after which he succeeded Mstislav the Old as grand prince of Kyiv.

In 1235 he was defeated and captured by the Cumans, losing Kyiv to Iziaslav; ransomed, he briefly retook it before yielding it to Yaroslav Vsevolodovich in 1236. He died at Ovruch in 1239, on the day the Mongols stormed Pereyaslavl.
