IB History Topic US Expansionist Foreign Policies Revision Notes (HL) | RevisionDojo

Background

Between 1880 and 1929, the United States transitioned from a relatively isolated republic to a global power.
Fueled by industrial growth, strategic ambitions, and nationalist ideology, U.S. leaders pursued expansion abroad by acquiring territories, intervening in Latin America, and reshaping hemispheric relations.
This era reflected the convergence of political, economic, social, and ideological forces driving foreign policy.

Political and Strategic Motivations

Politically, the United States sought to secure influence in the Caribbean and Pacific to protect trade routes and enhance national security.
Leaders such as Theodore Roosevelt and William McKinley believed territorial expansion would project U.S. strength and secure access to new naval bases.
The Monroe Doctrine (1823), originally a defensive statement against European colonization, evolved under Roosevelt’s Corollary (1904) into a justification for U.S. intervention to maintain regional stability.
Expansion was also tied to the balance of power. Policymakers feared European dominance in the Western Hemisphere if the U.S. did not assert itself.
