Vsevolod Olgovich, at this time Prince of Chernigov, the Cumans, and his allies who are invited by Iziaslav to make his point against Viacheslav, continue their war against Yaropolk and cross the Dnieper to loot the Kiev region.

After a decisive battle in 1135, Yaropolk has to cede the towns of Kursk and …

…Posechenoye, gained only seventeen years earlier.

Vsevolod is on May 28, 1136, confined in the Archbishop's courtyard (compound) in the Detinets along with his wife and family, guarded by thirty men so as not to escape.

He is allowed to leave Novgorod in mid-July, going to his uncle in Kiev.

The Novgorodans replace him with the brother of the Chernigov prince, Sviatoslav Olgovich.

They will soon be convinced convinced to replace Sviatoslav with Rostislav Yuryevich, the eldest son of Yuri Dolgoruki.

Vsevolod's dismissal from Novgorod has traditionally been seen as the end of Kievan power in the north and the beginning of the Republic of Novgorod.

After him, a number of princes will be invited in or dismissed over the next two centuries, although only a few, like Aleksandr Nevsky, will be able to assert themselves in the city for a prolonged period.

Vsevolod II of Kiev has two sons, but his chosen successor is his brother, Igor, and he has obtained pledges from his subjects to accept Igor as his heir.

According to one account, Vsevolod even had the Kievans kiss the Holy Cross and swear loyalty to Igor, which they resented.

Shortly before his death in 1146, Vsevolod becomes a monk under the name Gavriil.

Igor II and his family, the Olgovichi, are unpopular and there is resistance against his accession.

The chroniclers accuse Igor of being dishonest, greedy, scheming, and violent.

He has reigned less than two weeks before the Kievans invite his cousin and rival, Iziaslav Msistislavich, the oldest son of Mstislav Vladimirovich, Kniaz' (Prince) of Novgorod, to be their prince.

Reneging on a promise he had made not to seek power, Iziaslav attacks and defeats Igor and his brother Svyatoslav.

Svyatoslav escapes, but Igor becomes entrapped in some marshes and is unable to flee because of an infirmity in his legs.

He is captured, and Iziaslav has him thrown into a pit, where he languishes until autumn 1146, when, desperately ill, he requests permission to become a monk.

Iziaslav releases him, but Igor is so weak he has to be carried from the pit and nearly dies of illness.

He becomes a monk at the monastery of St. Feodor in Kiev under the name Ignati.

Iziaslav, who is already Prince of Pereyaslav (1132), Prince of Turov (1132-1134), Prince of Rostov, (1134- ), Prince of Vladimir and Volyn (1134—1142), and Prince of Pereyaslavl (1143-1145), now becomes Velikiy Kniaz (Grand Prince) of Kiev.
