Concept
American Expansionism refers to the period in U.S. history where the nation sought to expand its territory and influence across the North American continent and beyond, driven by a belief in manifest destiny and the desire for economic growth. This ideology justified the displacement of Native American tribes, the Mexican-American War, and the acquisition of territories such as Texas, California, and Alaska, shaping the geopolitical landscape of the United States.
Concept
The annexation of Texas in 1845 was a pivotal moment in American history, marking the expansion of U.S. territory and intensifying the sectional conflicts over slavery that would ultimately lead to the Civil War.

Concept
The Mexican-American War (1846-1848) was a pivotal conflict that resulted in the United States acquiring vast territories in the present-day American Southwest, including California and New Mexico, significantly shaping the nation's expansionist policies.

Concept
Westward expansion refers to the 19th-century movement of settlers into the American West, driven by the belief in Manifest Destiny and facilitated by land acquisitions and infrastructure developments like the transcontinental railroad.
