Understanding American Imperialism and the Spanish-American War
The late 19th century marked a pivotal shift in American imperialism as the United States emerged from its traditional isolationist stance. This transformation fundamentally shaped U.S. foreign policy and established America as a global power through American expansionism and military intervention.
Definition: American imperialism refers to the economic, military, and cultural influence of the United States over other countries, particularly during the late 1800s and early 1900s.
The United States underwent significant changes that drove its expansionist policies. Industrial growth created an urgent need for new markets and raw materials, while domestic challenges like economic depression and labor unrest pushed leaders to look beyond continental borders. These factors contributed to the 3 reasons for us expansion overseas in the late 19th century: economic opportunities, military strategic interests, and cultural influence.
The concept of Manifest Destiny, which had previously justified continental expansion, evolved to support overseas imperialism. This ideology merged with social Darwinism and economic interests to create a powerful argument for American global influence. The period saw the United States actively seeking territories and markets across the Pacific and Caribbean.
