Vasily Kosoy

Vasily Yuryevich Kosoy (c. 1403–1448), nicknamed the Squint, was the eldest son of Yury of Zvenigorod and prince of Zvenigorod from 1421. Dmitry Donskoy had placed Yury after Vasily I in the succession, but Vasily I passed the claim to his own sons.

When his father seized Moscow from Vasily II and died in 1434, Kosoy proclaimed himself grand prince. His brother Dmitry Shemyaka rejected him, joined Vasily II and drove him from the city in 1435. In 1436 Kosoy was defeated in Rostov province, captured and blinded, and he died in captivity in 1448.
