How did the territorial acquistion resulting from the spanish American war affect the US?

The territorial acquisitions resulting from the Spanish-American War, notably Puerto Rico, Guam, and the Philippines, marked a significant expansion of U.S. influence and territory beyond the continental borders. This shift established the U.S. as an imperial power, leading to increased involvement in global affairs and conflicts. The acquisition of these territories also sparked debates over colonialism, governance, and civil rights, particularly concerning the Philippines, which led to a prolonged conflict and the eventual establishment of a U.S. colonial administration. Overall, these changes laid the groundwork for America's emergence as a major player on the world stage in the 20th century.
