What was a primary cause of the Spanish-American War?

The primary cause of the Spanish-American War can be attributed to American imperialist interests in Spanish territories. In the late 19th century, the United States was driven by a desire to expand its influence and control beyond its borders, particularly in regions like the Caribbean and the Pacific. The explosion of the USS Maine in Havana harbor and sensationalist journalism, often referred to as "yellow journalism," fueled public outcry and desired intervention.

The U.S. government and many citizens saw an opportunity to assert American power by supporting Cuban independence from Spain, which aligned with broader imperialist ambitions. The conflict ultimately resulted in the U.S. gaining control over former Spanish colonies such as Puerto Rico, Guam, and the Philippines, marking a significant expansion of American territory and influence. This desire for territorial acquisition and the establishment of the United States as a global power were the central motives behind entering the war.
