Ch 17 Manifest DestinyTheme: American expansionism gained momentum in the 1840s, leading first to the acquisition of Texas and Oregon, and then to the Mexican War, which added vast southwestern territories to the United States and ignited the slavery question.

Theme: American international prestige grows as the United States expands. Successful military campaigns against Mexico along with well negotiated treaties with Britain force Europe to respect America more while Latin America begins to be wary of the “Colossus of the North.”
