Which treaty resulted in Spain ceding Florida to the United States?

The Adams-Onis Treaty, also known as the Transcontinental Treaty, was the agreement between the United States and Spain that led to Spain ceding Florida to the United States in 1819. This treaty was significant not only for the acquisition of Florida but also because it defined the borders between the United States and New Spain (now Mexico).

In addition to Florida's cession, the treaty also resolved ongoing territorial disputes between the two nations, allowing the U.S. to claim lands west of the Mississippi River while Spain maintained its territories in the southwest. The treaty reflected the expansionist desires of the United States during this period and played a key role in the nation's growth.

While the Treaty of Ghent ended the War of 1812, the Treaty of Paris ended the Revolutionary War and recognized American independence, and the Treaty of Fort Laramie pertains to agreements with Native American tribes. Thus, the correct answer highlights a crucial moment in U.S. territorial expansion that is distinctly attributed to the Adams-Onis Treaty.
