I Searched It This Is What Came Up
In the 18th century, Great Britain and the French Crown disputed for control of this region. The French had claimed it in the 17th century as part of the New France Province of Quebec; the competition between the nations was one cause of the French and Indian War (known as the Seven Years' War in Europe). After Britain gained control following its defeat of France in 1763, its attempts to reserve the territory for use by Native Americans under the Royal Proclamation of 1763 roused resentment among British colonists, who were already seeking to settle west of the Appalachian Mountains.
