Andrei II of Russia

Prince Andrey II Yaroslavich (Андрей Ярославич) (c. 1222 – 1264) was the third son of Yaroslav II who succeeded his uncle Svyatoslav III as the Grand Duke of Vladimir in 1249. Three years later, he challenged the Mongols and was ousted by them from Russia.

In 1240 Novgorodians expelled his brother, Alexander Nevsky, from the city and asked Yaroslav II to send them another commander. Andrey was sent to the wayward republic instead, only to leave it several months later. When the city was attacked by Teutonic Knights, Yaroslav again sent Andrey with several units to help. In 1242, Andrey joined his Suzdalian forces with Alexander's and saw action in the celebrated Battle on the Ice.

In 1247, when their father died, Andrey and Alexander went to Karakorum in Mongolia, where Andrey was appointed the next Grand Duke of Vladimir by Guyuk khan. On their return to Vladimir two years later, they found that the capital had been seized by their young brother Mikhail Khorobrit. The latter, however, was killed in battle with Lithuanians several months later.

Upon ascending the golden throne of his fathers, Andrey resolved to assert some independence from the Horde. He married a daughter of Danylo of Halych, who was the Mongols' avowed enemy. A year later, his uncle Svyatoslav, offended by his ousting from Vladimir, went to the Horde to secure the throne for himself. He was followed by Alexander Nevsky, who blamed Andrey for appropriating a portion of tribute due to the Horde. The khan sent a punitive expedition which defeated Andrey near Pereslavl. Novgorod didn't want to give him shelter, either, so that Andrey had to escape to Kolyvan and then to Sweden.
