Which U.S. president is often associated with American imperialism during the late 19th century?

The association of William McKinley with American imperialism during the late 19th century stems from key events and policies that occurred during his presidency from 1897 to 1901. McKinley was president during the period that saw the United States become significantly involved in overseas expansion, marked notably by the Spanish-American War in 1898.

Under McKinley’s administration, the U.S. engaged in this conflict primarily to support Cuban independence from Spain, which highlighted a growing interest in imperialism driven by both humanitarian and economic motives. The outcome of the war resulted in the U.S. acquiring territories such as Puerto Rico, Guam, and the Philippines, further solidifying America's status as an imperial power.

Additionally, McKinley's policies reflected the prevailing attitudes of the time, including the belief in Manifest Destiny and the idea that the United States was destined to expand its influence and territory. His administration's actions set precedent for future American involvement in foreign territories, making him a prominent figure in the narrative of American imperialism.
