The Treaty of Paris was signed on 10 February 1763, and ended the wars between Great Britain, France, Spain, and Portugal.
Using the Mississippi River as a dividing line, France officially gave the western half to Spain, and the eastern half (including Baton Rouge) to Great Britain. The island of New Orleans remained French.
Britain gave Havana (which they had captured) back to Spain.
Spain gave Florida to Britain, which would then divide it into West Florida and East Florida, using the Apalachicola River as a border.
