Polish–Russian War (1654–1667)
Conflict in Eastern Europe
The Polish–Russian War of 1654–1667 was a major conflict between the Tsardom of Russia and the Polish–Lithuanian Commonwealth. Between 1655 and 1660, the Swedish invasion was also fought in the Polish–Lithuanian Commonwealth and so the period became known as "The Deluge". The Commonwealth initially suffered defeats, but it regained its ground and won several decisive battles.
