Detailed explanation-2: -In 1823 U.S. President James Monroe proclaimed the U.S. protector of the Western Hemisphere by forbidding European powers from colonizing additional territories in the Americas. In return, Monroe committed to not interfere in the affairs, conflicts, and extant colonial enterprises of European states.

Detailed explanation-3: -The three main concepts of the doctrine-separate spheres of influence for the Americas and Europe, non-colonization, and non-intervention-were designed to signify a clear break between the New World and the autocratic realm of Europe.
