How did the US protected the the new republics of Latin America?

The United States protected the new republics of Latin America primarily through the Monroe Doctrine, established in 1823, which asserted that European powers should no longer interfere in the affairs of the Americas. The Doctrine served as a warning against colonization or intervention in the newly independent nations. Additionally, the U.S. offered diplomatic recognition and economic support to these republics, fostering political stability and encouraging their sovereignty against European influence.
