The first (164246) and second (164849) wars pitted the supporters of King Charles I against the supporters of the Long Parliament, while the third (164951) saw fighting between supporters of King Charles II and supporters of the Rump Parliament. The war ended with the Parliamentarian victory at the Battle of Worcester on 3 September 1651.  - Worcester is a city in Worcestershire, England, southwest of Birmingham and north of Gloucester. The population is approximately 100,000. The River Severn flanks the western side of the city centre, which is overlooked by the 12th-century Worcester Cathedral.  - Chelsea is an affluent area in southwest London, bounded to the south by the River Thames. Its frontage runs from Chelsea Bridge along the Chelsea Embankment, Cheyne Walk, Lots Road and Chelsea Harbour. Its eastern boundary was once defined by the River Westbourne, which is now in a pipe above Sloane Square tube station. The modern eastern boundary is Chelsea Bridge Road and the lower half of Sloane Street, including Sloane Square. To the north and northwest, the area fades into Knightsbridge and Brompton, but it is considered that the area north of King's Road as far northwest as Fulham Road is part of Chelsea. The football club Chelsea F.C. is based at Stamford Bridge in neighbouring Fulham.  - Roundhead was the name given to the supporters of the Parliament of England during the English Civil War. Also known as Parliamentarians, they fought against Charles I of England and his supporters, the Cavaliers or Royalists, who claimed rule by absolute monarchy and the divine right of kings. The goal of the Roundhead party was to give the Parliament supreme control over executive administration.  - Viscount Newhaven was a title in the Peerage of Scotland. It was created in 1681 for Charles Cheyne (or Cheyney), Member of Parliament and Clerk of the Pipe. He was made Lord Cheyne at the same time, also in the Peerage of Scotland. He married Lady Jane Cavendish, daughter of the first Duke of Newcastle and had a son, William Cheyne, who became 2nd Viscount Newhaven. William was a landowner in Chelsea, London, having purchased Henry VIII's palace. He died in 1728 leaving no male heir, the titles becoming extinct.  - The Battle of Worcester took place on 3 September 1651 at Worcester, England, and was the final battle of the English Civil War. Oliver Cromwell's Parliamentarian "New Model Army", 28,000 strong, defeated King Charles II's 16,000 Royalists, of whom the vast majority were Scottish.  - Cavalier first used by Roundheads as a term of abuse for the wealthier male Royalist supporters of King Charles I and his son Charles II of England during the English Civil War, the Interregnum, and the Restoration (1642  c. 1679). 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.  - The Peerage of Scotland is the section of the Peerage of the British Isles for those peers created by the King of Scots before 1707. Following that year's Treaty of Union, the Kingdom of Scots and the Kingdom of England were combined under the name of Great Britain, and a new Peerage of Great Britain was introduced in which subsequent titles were created.  - England is a country that is part of the United Kingdom.
