Explanation:

The Monroe Doctrine was significant as it declared that the Americas were no longer open to European colonization and warned European powers against interfering in the affairs of the newly - independent American states. It helped establish the United States as a regional power and set a precedent for U.S. foreign policy in the Western Hemisphere. Marshall court decisions, such as McCulloch v. Maryland and Gibbons v. Ogden, increased the power of the national government by upholding the constitutionality of the national bank (affirming the implied powers of Congress) and strengthening Congress's power to regulate interstate commerce respectively.

The Monroe Doctrine declared the Americas off - limits to European colonization and warned against interference in American affairs, helping establish U.S. regional power.
