[citation needed] According to the Novgorod First Chronicle (NPL), the Novgorodians expelled his brother Alexander Nevsky from the city in the winter of 1240–1241, and asked their father Yaroslav II to send them another commander.
[1] In 1241, Andrey joined his Suzdalian forces with Alexander's, and they jointly retook Pskov, raided the Estonian (Chud') countryside, and saw action in the Battle on the Ice.
[4] In the winter of 1250–1251, some time after taking the throne of Vladimir, Andrey married Ustynia, a daughter of Danylo of Halych,[6][7] who had submitted to Batu Khan in 1245[8] and was well-received in Sarai, but by 1251 appears to have attempted forming an anti-Mongol coalition.
[9] With his brother Andrey exiled, Alexander Nevsky submitted to Möngke Khan, and as a reward for his loyalty to the Golden Horde, he received the throne of Vladimir from the Mongols (1252).
[citation needed] After Alexander died in 1263, Andrey aspired to add Vladimir to his possessions, but was thwarted in his designs by his younger brother Yaroslav of Tver.
