Sviatoslav III of Vladimir

Sviatoslav Vsevolodovich of Vladimir (Russian: Святослав III Всеволодович) (27 March 1196 – 3 February 1252) was the Prince of Novgorod (1200–1205, 1207–1210) and Grand Prince of Vladimir-Suzdal (1246–1248).

Sviatoslav Vsevolodovich was the sixth son of Vsevolod the Big Nest and Maria Shvarnovna. During the partition of his father's lands, he received the town of Yuriev-Polsky. It was he who commissioned the town's principal landmark, the Cathedral of St. George, constructed in 1230-34. In 1220 Sviatoslav sacked Aşlı in Volga Bulgaria.

Sviatoslav's reign in Vladimir was short and uneventful. In 1248, his nephew Mikhail Khorobrit of Moscow, in defiance of the centuries-old succession system, seized the city of Vladimir and ousted Sviatoslav back to Yuriev-Polsky. Two years later, Sviatoslav and his son visited the Golden Horde, pleading with the Khan to reinstate him on the grand princely throne. He died on 3 February 1252 and was buried in Yuriev-Polsky.
