THE MONROE DOCTRINE

Why was the Monroe Doctrine important?

In 1823 U.S. President James Monroe proclaimed the United States as protector of the Western Hemisphere. The doctrine became a mainstay of U.S. foreign policy, laying the groundwork for U.S. expansionist and interventionist practices in the decades to come.

What were the basic tenets of the Monroe Doctrine?

The Monroe Doctrine’s first two tenets promised that the U.S. would not interfere with European states’ affairs, conflicts, and extant colonial enterprises.

The other two stipulated that the Western Hemisphere was no longer open to further colonization and that any attempt on the part of a European power to do so would be understood by the U.S. as an act of aggression.

What motives were behind the Monroe Doctrine?

The U.S. government was worried that European powers, particularly Russia, Spain, and France, would encroach on the U.S. sphere of influence by carving out colonial territories in the Americas.

Who worked on the Monroe Doctrine?

George Canning, British foreign minister to the U.S., suggested that the two countries make a joint declaration, because both had motives for limiting colonialism (besides their own) in the Americas.

U.S. Secretary of State John Quincy Adams advised against the idea, and U.S. President James Monroe ultimately issued a unilateral declaration to avoid any hindrance to the U.S.’s own expansionist designs.

How did the Monroe Doctrine change over time?

The U.S. did not have the military might to enforce the Monroe Doctrine when it was drafted.

After the U.S. emerged as a global power, the 1904 Roosevelt Corollary to the Monroe Doctrine asserted the United States’ role as police of the Western Hemisphere and its right to involve itself in Latin American affairs.
