Rostislav Yaroslavich

[1] In 1192, his father sent him when the Olgovichi (the members of the dynasty of Chernigov) commanded by Igor Svyatoslavich launched an expedition against the Cumans.

[1][failed verification] The Olgovichi ventured deep into the steppe, but the nomads assembled in great numbers and awaited the princes.

[1][failed verification] On 11 July 1186, Rostislav married Vseslava Vsevolodovna, a daughter of prince Vsevolod Yurevich of Suzdalia.

[1] When all the princes assembled in Kiev in 1223, Mikhail Vsevolodovich was the second in seniority among the Olgovichi which suggests that both Rostislav and Yaropolk had died by that time.
