The Treaty of Paris 1783 concluded the American Revolution. It established a boundary between the United States and British North America. The agreement gave the United States lands reserved for Indigenous peoples, which betrayed earlier treaties and alliances between the British and Indigenous peoples. The British Crown formally recognized American independence and ceded most of its territory east of the Mississippi River to the United States, doubling the size of the new nation and paving the way for westward expansion.
The 1783 Treaty of Paris marked the culmination of the American Revolutionary War, delineating the border between the newly independent United States and the territories of British North America. This settlement transferred vast tracts of land designated for Native American tribes to American control, contravening prior agreements and partnerships between Indigenous populations and the British. With the formal recognition of the United States' sovereignty, Britain relinquished the majority of its holdings to the east of the Mississippi River. This cession significantly expanded the territory of the nascent United States, setting the stage for its continued expansion to the west.
