How did James Monroe expand the country's borders?

Answer 1

James Monroe expanded the United States' borders primarily through the acquisition of Florida from Spain in 1819, finalized by the Adams-Onís Treaty. Additionally, his presidency coincided with the doctrine of Manifest Destiny, which encouraged westward expansion. Monroe also supported the idea of the United States asserting influence over the Western Hemisphere, exemplified by the Monroe Doctrine of 1823, which warned European powers against further colonization in the Americas. These actions collectively contributed to the territorial growth of the nation.
