The Spanish-American War was a brief conflict in 1898 between the United States and Spain. The United States emerged victorious and as a result, gained control of several territories, including Puerto Rico, Guam, and the Philippines. The acquisition of these territories marked the beginning of the United States as a colonial power.
The United States also gained significant influence in Cuba, which had been a Spanish colony. The United States helped Cuba gain independence from Spain, and in return, the United States was granted significant economic and political influence in Cuba.

The war also helped to strengthen the United States military, which would play a significant role in World War I and other conflicts in the years to come.
