Answer:
In 1823, John Quincy Adams helped President James Monroe draw up a document that protected the interests of the United Sates in Mexico and Latin America. This document was called the Monroe Doctrine.
Explanation:
The Monroe Doctrine was a declaration of principles of US foreign policy, which stated that the American continent would be only under the sphere of influence of the United States of America, which would prevent European nations to interfer with it, proclaimed on December 2, 1823 by President D. Monroe.
This doctrine declared that European states should no longer be allowed to colonize or intervene and interfere with the new independent American nations (both in North and South America). The United States should seek to remain neutral in wars between European states and their colonies, but in the event that wars of this kind develop on the American continents, the United States would consider such acts hostile. The doctrine was authored by Secretary of State John Quincy Adams.
