What did the United States promise in the Monroe Doctrine?

The United States promised two main principles in the Monroe Doctrine. Firstly, it declared that any attempt by European powers to colonize or interfere with any nation in the Western Hemisphere would be viewed as a threat to the United States' own security and interests. The doctrine stated that the United States would not intervene in existing European colonies or interfere in the internal affairs of European nations.

Secondly, the United States pledged that it would not meddle in the existing European colonies in the Western Hemisphere or in the internal affairs of any European nation. It aimed to establish a separation between the Eastern Hemisphere, where Europe held influence, and the Western Hemisphere, where the United States aspired to dominate. Essentially, the Monroe Doctrine was a statement that advocated for non-colonization and non-interference by European powers in the Western Hemisphere, while reaffirming the right of the United States to protect its own interests and security.
