What territory was added to the US as a result of the Adams onis treaty?

The Adams-Onís Treaty, signed in 1819, resulted in the United States acquiring Florida from Spain. In addition to Florida, the treaty defined the boundary between the U.S. and New Spain (modern-day Mexico), ceding some territories in the west, including parts of present-day Texas and the Pacific Northwest, but primarily focused on Florida's transfer. This agreement helped to reduce tensions between the two nations and solidified U.S. territorial claims in the region.
