1.The Spanish-American War (1898): In response to Spain's harsh treatment of Cuban rebels and the sinking of the USS Maine in Havana harbor, the United States declared war on Spain. The war resulted in the defeat of Spain and the expansion of US influence in the Caribbean and the Pacific.
2.The Roosevelt Corollary (1904): President Theodore Roosevelt expanded the Monroe Doctrine in 1904, stating that the US had the right to intervene in the affairs of Latin American countries to prevent European intervention and protect American interests.
3.Dollar Diplomacy: Under President William Howard Taft, the US used economic means, such as loans and investments, to influence the policies of Latin American countries and promote American economic interests.
4.The Panama Canal: The United States supported Panama's independence from Colombia in 1903 and acquired the Panama Canal Zone, which allowed for the construction of the Panama Canal. The canal significantly reduced travel time between the Atlantic and Pacific Oceans and strengthened the US military presence in the region.
5.Interventions in Latin America: Throughout the late 19th and early 20th centuries, the United States intervened militarily in several Latin American countries, such as Cuba, Haiti, Nicaragua, and the Dominican Republic, to protect American citizens, economic interests, and to promote stability in the region.
These actions demonstrated the US's commitment to maintaining dominance and influence in the Western Hemisphere and its adherence to the principles of the Monroe Doctrine.
