The Spanish-American War was a war between the United States and Spain in 1898. The main issue at play in this conflict was that of Cuban independence. The U. S. backed the Cuban rebels that seeked independence. The public was greatly influenced by a media campaign of anti-Spanish sentiments.

The United States eventually emerged victorious, and this meant the loss of the last remnants of the Spanish Empire, which was a great shock to Spain. However, the U. S. gained several territorial possessions, fuelling an interest in expansionism.
