What people moved out of Florida after the Adams-Onis Treaty was signed?

After the Adams-Onís Treaty was signed in 1819, which ceded Florida from Spain to the United States, many Spanish settlers and loyalists moved out of Florida. Additionally, some Native American groups, particularly the Seminoles, began to relocate in response to the changing political landscape and pressures from American settlers. The shift marked a significant demographic change in the region as new American settlers began to move in.
