Answer:
U.S. victory in the war produced a peace treaty that compelled the Spanish to relinquish claims on Cuba, and to cede sovereignty over Guam, Puerto Rico, and the Philippines to the United States. The United States also annexed the independent state of Hawaii during the conflict.
The immediate cause of the Spanish-American War was Cuba's struggle for independence from Spain. ... Growing U.S. economic, political, and military power, especially naval power, contrasted with waning Spanish power over its far-flung colonies, made the war a relatively short-lived conflict.
