What was the primary purpose of the Adams-Onís Treaty?

The primary purpose of the Adams-Onís Treaty was to cede Florida from Spain to the United States. Signed in 1819 and ratified in 1821, the treaty resolved longstanding tensions between the United States and Spain, particularly over territorial disputes in North America. The acquisition of Florida was significant for the U.S. as it eliminated the Spanish presence on the eastern border, reduced the potential for conflict, and opened the way for American expansion southward. Through this treaty, the U.S. not only gained Florida but also defined the boundary between the United States and New Spain (now Mexico), which was crucial for territorial clarity and security. This marked an important step in the westward expansion of the United States and reflected the growing influence and ambition of the nation during that era.
