The conflict is known by multiple names. In British America, wars were often named after the sitting British monarch, such as King William's War or Queen Anne's War. There had already been a King George's War in the 1740s during the reign of King George II, so British colonists named this conflict after their opponents, and it became known as the French and Indian War. This traditional name continues as the standard in the United States, but it obscures the fact that Indians fought on both sides of the conflict and that this was part of the Seven Years' War, a much larger conflict between France and Great Britain. American historians generally use the traditional name or sometimes the Seven Years' War. Less frequently used names for the war include the Fourth Intercolonial War and the Great War for the Empire. In Europe, the North American theater of the Seven Years' War usually is not given a separate name. The entire international conflict is known as the Seven Years' War. "Seven Years" refers to events in Europe, from the official declaration of war in 1756 to the signing of the peace treaty in 1763. These dates do not correspond with the fighting on mainland North America, which was largely concluded in six years, from the Battle of Jumonville Glen in 1754 to the capture of Montreal in 1760. Canadians refer to both the European and North American conflicts as the Seven Years' War . French Canadians also use the term "War of Conquest" , since it is the war in which Canada was conquered by the British and became part of the British Empire.
