Why did America expand its involvement in Latin America?

America expanded its involvement in Latin America primarily to protect its economic interests and promote stability in the region. The Monroe Doctrine of 1823 asserted U.S. influence, warning European powers against further colonization in the Americas. Additionally, during the late 19th and early 20th centuries, the U.S. sought to counteract European influence, leading to interventions and support for regimes aligned with American interests. This expansion was also driven by a belief in Manifest Destiny and the desire to spread democratic ideals.
