Anglo-Scottish war (1650–1652)
The Anglo-Scottish war (1650–1652), also known as the Third Civil War, was the final conflict in the Wars of the Three Kingdoms, a series of armed conflicts and political machinations between shifting alliances of religious and political factions in England, Scotland and Ireland. The 1650 English invasion of Scotland was a pre-emptive military incursion by the English Commonwealth's New Model Army, intended to allay the risk of Charles II invading England with a Scottish army.
