Deluge (history)
The Deluge was a series of mid-17th-century military campaigns in the Polish–Lithuanian Commonwealth. In a stricter sense, the term refers to the Swedish invasion and occupation of the Commonwealth as a theatre of the Second Northern War (1655–1660) only; in Poland and Lithuania this period is called the Swedish Deluge (Polish: potop szwedzki, Lithuanian: švedų tvanas, Swedish: svenska syndafloden), or less commonly the Russo–Swedish Deluge (Polish: Potop szwedzko-rosyjski) due to the simultaneous Russo-Polish War.
