What term describes the 19th-century belief that the United States should expand across the North American continent?

• A. Monroe Doctrine
• B. Isolationism
• C. Imperialism
• D. Manifest Destiny

Answer: (D)

The main idea being tested is a belief in expanding United States territory across North America. This mindset is Manifest Destiny. In the 1800s, many Americans felt the nation was destined to stretch from the Atlantic to the Pacific, guiding policies and actions that encouraged settlement, territorial acquisition, and westward movement. It gave a sense of mission to spread American democracy and institutions across the continent, shaping events like westward migration, the annexation of Texas, the Oregon possessions, and the Mexican-American War. By comparison, the Monroe Doctrine focused on keeping European powers from colonizing or meddling in the Western Hemisphere, not on U.S. expansion itself. Isolationism describes staying out of foreign affairs, and imperialism refers to acquiring distant colonies or extending power overseas, which is different from the idea of continental expansion.
