Sviatoslav III Vsevolodovich (died 1194) was Prince of Turov (1142 and 1154), Volhynia (1141–1146), Pinsk (1154), Novgorod-Seversk (1157–1164), Chernigov (1164–1177), Grand Prince of Kiev (1174; 1177–1180; 1182–1194). He was the son of Vsevolod II Olgovich.[2]
He succeeded in taking the Kievan throne from Yaroslav II, and ruled Kiev alongside Rurik Rostislavich until his death. The co-princedom did not go smoothly and there were disagreements between Sviatoslav and Rurik, until Sviatoslav was taken ill and died on 27 July 1194.
