What major conflict involved the Spanish-American War as a part of U.S. imperialism?

The Spanish-American War, which occurred in 1898, marked a significant turning point in U.S. history, particularly in terms of imperialism. This conflict led to the United States emerging as a global power, shifting its focus outside its continental borders. The war resulted in the U.S. acquiring territories like Puerto Rico, Guam, and the Philippines, illustrating America's commitment to expanding its influence and presence globally, which aligns with the broader concept of imperialism.

While World War I, which took place from 1914 to 1918, was indeed a major conflict for the United States that involved military engagement and the assertion of power, it does not directly relate to the Spanish-American War in the same way. Instead, World War I can be seen more as a culmination of ongoing global tensions and alliances that had formed over the decades, reflecting different factors than those at play in the Spanish-American War. The earlier war set the stage for the U.S. to become more involved internationally, paving the way for its participation in conflicts like World War I and establishing a precedent for military intervention in global affairs.
