In the decades before Pontiac's rebellion, there were a number of wars in Europe which also had an influence on the French and Indian Wars in North America. The largest of these wars was the Seven Years' War. In this war, France lost New France in North America to Great Britain. The Shawnee and Lenape had also fought in this war. The Treaty of Easton was signed in 1758, and brought peace with these tribes. In the treaty, the British promised not to settle further beyond the ridge of the Alleghenies. This line was confirmed in 1763, but few people respected it. Most fighting in the North American theater of the war, generally referred to as the French and Indian War in the United States, came to an end after British General Jeffrey Amherst captured Montreal, the last important French settlement, in 1760.
