Yaroslav II of Vladimir

Yaroslav II Vsevolodovich (; Christian name: Theodore ; 8 February 1191 – 30 September 1246), also transliterated as Iaroslav, was Grand Prince of Vladimir from 1238 to 1246. He collaborated with Batu Khan following the Mongol invasion, before he was ultimately poisoned.

Prince of Pereyaslav Yaroslav was the fourth son of Vsevolod the Big Nest and Maria Shvarnovna.

In 1200, he was sent by his father to rule the town of Pereiaslav near the Kypchak steppes. Six years later, he was summoned by boyars of Halych to rule their city but could not effectively claim the throne. Thereupon he was sent to take Ryazan, but the stubborn opposition of the inhabitants led to the city being burnt. In 1209, Vsevolod sent Yaroslav to oppose Mstislav the Bold in Novgorod. After several battles, the two princes made peace, whereby Yaroslav married Mstislav's daughter.

Upon his deathbed, Vsevolod the Big Nest bequeathed to him Pereslavl-Zalessky. In the conflict between his elder brothers Konstantin and Yuri, Yaroslav supported the latter. In 1215, he accepted the offer of the Novgorodians to become their prince but, desiring revenge for their former treachery, captured Torzhok and blocked its supplies of grain to Novgorod. Several months later, he was defeated by his father-in-law on the Lipitsa River and had to retreat to Pereslavl; a helmet that he lost during the battle would be retrieved by archaeologists in 1808. A helmet lost by Yaroslav in the aftermath of the Lipitsa Battle and retrieved by a peasant in 1808.

Prince of Novgorod and Kiev

His next ambition was to subjugate Pskov, but the Novgorodians refused to make war against its neighbour. Yaroslav departed in anger and seized the Novgorodian enclave of Volokolamsk. In 1234, he returned to Novgorod and several years later defeated its chief enemies—Lithuanians and the Teutonic Knights. In 1236, he followed Daniel of Galicia's advice and moved from Novgorod to Kiev, leaving his son Alexander as his representative in the north.

Grand Prince of Vladimir In 1238, when the Mongols first invaded Kievan Rus' and his elder brother Yuri was killed in battle, Yaroslav left Kiev for Vladimir, where he was crowned grand prince. Yaroslav attempted to restore the cities of Vladimir-Suzdal after the Mongol ravages and fires. In 1243, he was summoned by Batu Khan to his capital Sarai. After a lengthy conference, he returned to Vladimir with honours. Two years later, he was again summoned to the east, this time by Güyük Khan in Karakorum. There he was poisoned by the Great Khan's mother Töregene and died a week after he had been allowed to return home .
