Sviatoslav III of Kiev
Sviatoslav III Vsevolodovich (c. 1123–1194), eldest son of Vsevolod II Olgovich, took Chernigov in 1164 after holding several lesser principalities. He seized Kiev from Yaroslav II Iziaslavich and, after his long northern campaign of 1180–1181 against Vsevolod the Big Nest, ruled the city while Rurik Rostislavich held the surrounding Kievan land.
In the steppe he captured the Cuman khan Kobyak and defeated Khan Konchak. In 1185, after his kinsman Igor's defeat, he relieved Pereyaslavl, and he died on 27 July 1194.
