No Peace Without Spain was a popular British political slogan of the early eighteenth century. It referred to the ongoing War of the Spanish Succession (1701–1714) in which Britain was a leading participant. It implied that no peace treaty could be agreed with Britain's principal enemy Louis XIV of France that allowed Philip, the French candidate, to retain the Spanish crown. The term became a rallying cry for opposition to the Tory government of Robert Harley, Earl of Oxford and the terms of the Treaty of Utrecht.
