Answer:
Step-by-step explanation:
During the long 19th century, U.S foreign policy was characterized by territorial expansion and a desire for economic growth. The Monroe Doctrine, established in 1823, declared that any attempt by European powers to colonize or interfere with states in the Americas would be viewed as a hostile act. This policy was aimed at protecting the newly independent Latin American states from European influence and solidifying U.S dominance in the region.
The U.S also pursued territorial expansion through military conquest and diplomacy. The Mexican-American War (1846-1848) resulted in the annexation of Texas and the cession of territory that would become California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado, Wyoming, Kansas, and Oklahoma. The U.S also acquired Alaska from Russia in 1867 and Hawaii was annexed in 1898. These acquisitions were driven by a desire for resources, markets, and strategic military positioning.
In addition to territorial expansion, the U.S also pursued economic growth through trade agreements and intervention in Latin America. The Open Door Policy, established in 1899, called for equal trading rights for all nations in China and helped to secure U.S access to Chinese markets. The U.S also intervened militarily in several Latin American countries to protect American business interests and promote political stability. This policy became known as the Big Stick Policy and was exemplified by President Theodore Roosevelt's intervention in Panama to secure control of the Panama Canal Zone.
Overall, U.S foreign policy during the long 19th century was characterized by a desire for territorial expansion, economic growth, and political dominance in the Western Hemisphere.
