Nalyvaiko Uprising
The Nalyvaiko Uprising was a Cossack rebellion against the Polish–Lithuanian Commonwealth. Headed by Severyn Nalyvaiko, it lasted from 1594 to 1596. The second in a long series of Cossack uprisings, the conflict was ultimately won by the Crown of Poland, but two years of warfare and scorched-earth tactics employed by both sides left much of Right-bank Ukraine in ruins.
