English Civil War: Royalists commanded by King Charles I suffered a significant defeat at the Battle of Rowton Heath.

The English Civil War or Great Rebellion was a series of civil wars and political machinations between Royalists and Parliamentarians in the Kingdom of England from 1642 to 1651. Part of the wider 1639 to 1653 Wars of the Three Kingdoms, the struggle consisted of the First English Civil War and the Second English Civil War. The Anglo-Scottish War of 1650 to 1652 is sometimes referred to as the Third English Civil War.

The term Cavalier was first used by Roundheads as a term of abuse for the wealthier royalist supporters of Charles I of England and his son Charles II during the English Civil War, the Interregnum, and the Restoration. It was later adopted by the Royalists themselves. Although it referred originally to political and social attitudes and behaviour, of which clothing was a very small part, it has subsequently become strongly identified with the fashionable clothing of the court at the time. Prince Rupert, commander of much of Charles I's cavalry, is often considered to be an archetypal Cavalier.

Charles I was King of England, Scotland, and Ireland from 27 March 1625 until his execution in 1649.

The Battle of Rowton Heath, also known as the Battle of Rowton Moor, occurred on 24 September 1645 during the English Civil War. The Parliamentarians, commanded by Sydnam Poyntz, inflicted a significant defeat on the Royalists under the personal command of King Charles I, inflicting heavy losses and preventing Charles from relieving the siege of Chester.
