At the end of the French and Indian War in 1763, Great Britain gained control of the territory between the Appalachians and the Mississippi River except for the New Orleans area. The northern boundary of West Florida was first established at 31 degrees north latitude.
It was soon determined that settlement was too restricted. In 1764, Great Britain moved the boundary north to 32 degrees, 28 minutes into the land of the Choctaws and Creeks.
