According to the Hypatian Chronicle, in 1234, Vladimirovich, with the help of the nomadic Polovtsy, campaigned against Vladimir Riurikovich and Daniil Romanovich of Volyn' and Galich.
According to the Novgorod First Chronicle, Prince Iziaslav and the Polovtsy joined Mikhail and troops from Chernigov to successfully attack and capture Kiev.
The Hypatian Chronicle states that Iaroslav Vsebelodovich took Kiev from Vladimir who was replaced by Mikail.
The Novgorod Chronicle and, to a certain extent, the Nikon Chronicle, on the other hand, states that Iziaslav occupied Kiev after Vladimir was captured in 1235 implying that he replaced Iziaslav Mstislavich and not Vladimir.
