From 1639 to 1653, there was fighting in England, Scotland and Ireland, three separate countries that were ruled by the same king. The fighting that took place in each of these countries broke out at different times and for different reasons. In England, it lasted from 1642 to 1651. Some people think of this as one big war, while others think of it as three separate wars: the First English Civil War (1642-46), the Second English Civil War (1648) and the Third English Civil War (1649-51). The wars are also sometimes known as the Wars of the Three Kingdoms, including the Bishops' Wars in Scotland in 1639 to 1640 and the Irish Rebellion from 1641 to 1653.
