Question

Which president put a firm stamp on the concept of isolationism in the early 1800s?

1) Washington
2) Adams
3) Madison
4) Monroe

Answer 1

James Monroe firmly established the concept of isolationism in U.S. foreign policy with the issuance of the Monroe Doctrine in the early 19th century.

Step-by-step explanation:

The president who put a firm stamp on the concept of isolationism in the early 1800s was James Monroe. The cornerstone of this policy was the Monroe Doctrine, a declaration that warned European powers against further colonization or interference in the affairs of the Western Hemisphere.

Drafted in part by Secretary of State John Quincy Adams, the Monroe Doctrine asserted that the politics of the Americas would be distinctly separate from Europe, and any attempt at colonization would be viewed as an act of aggression, ultimately setting a precedent for the United States' future foreign policy.
