Early American Imperialism was the policy by which stronger nations exerted control over weaker nations through economic, political, or military means. Fueled by the concept of Manifest Destiny, the need for national security, and the search for new markets, such as in China, the U.S. expanded significantly during the 19th century. George Washington's Farewell Address warned against military alliances and advocated for isolationism. Key events include the annexation of Texas, the Oregon boundary dispute, and territorial gains from the Mexican-American War facilitated by President James K. Polk.
