Answer:
Territorial Expansion: As a result of the Treaty of Paris of 1898, which ended the war, the United States acquired several new territories, most notably Puerto Rico, Guam, and the Philippines. This expansion increased the U.S. presence in the Pacific and the Caribbean, positioning it as a global colonial power.
Establishment of Overseas Territories: The United States established colonial rule in the newly acquired territories, marking the beginning of the American Empire. These territories provided military bases and coaling stations, enhancing American influence and power projection in the Pacific and Latin America.
Emergence as a Naval Power: The Spanish-American War showcased the importance of a modern navy, and the United States Navy's victory over the Spanish fleet in the Battle of Santiago de Cuba highlighted its capabilities. The U.S. subsequently invested in building a stronger navy, contributing to its status as a major naval power.
Shift in Foreign Policy: The war marked a shift in American foreign policy, moving away from isolationism toward a more interventionist and imperialistic approach. The U.S. began to assert its interests in regions beyond its borders, becoming more involved in international affairs.
Monroe Doctrine and Regional Influence: The U.S. reinforced the Monroe Doctrine, which aimed to limit European influence in the Western Hemisphere. The acquisition of territories in the Caribbean and Pacific further solidified its regional dominance and influence.
Economic Interests: The United States benefited economically from the war by gaining access to new markets, especially in Asia. The acquisition of the Philippines opened up trade opportunities in the Asia-Pacific region, laying the foundation for American economic interests in that part of the world.
Global Recognition: The successful outcome of the Spanish-American War and the acquisition of new territories raised the profile of the United States on the global stage. It gained recognition as a major player in international politics and diplomacy.
Military Modernization: The war prompted the United States to modernize its military and develop a standing army, which would be crucial in its role as a world power in the 20th century.
Role in Latin America: The United States became more involved in the affairs of Latin American countries, both economically and politically, as it sought to protect its interests in the region.
