Vasily Kosoy

In the beginning, Yury Dmitrievich accepted the rule of Vasily II's regency, but when the ruler became of age in 1433, he started a rebellion.

Yury Dmitrievich defeated the forces of Vasily II and proclaimed himself Grand Prince of Moscow.

This change of leadership resulted in the revolt of Dmitry Shemyaka who refused to accept his brother's rule.

The decisive battle of this civil war was fought on 14 May 1436 near the village of Skoryatin in the Rostov province where Kosoy was defeated, imprisoned and shortly afterwards blinded.
