The Treaty of Paris of 1783 ended the American Revolutionary War between Great Britain and the United States. In the second article of the Treaty, the parties agreed on all boundaries of the United States, including, but not limited to, the boundary to the north along then-British North America. The agreed-upon boundary included the line from the northwest angle of Nova Scotia to the northwesternmost head of Connecticut River, and proceeded down along the middle of the river to the 45th parallel of north latitude.
