AP US History
The 1840s was a transformative decade in American history characterized by significant social, political, and economic changes, including a surge in migration and immigration. During this period, many Americans moved westward in search of new opportunities, while large numbers of immigrants arrived, particularly from Ireland and Germany, drawn by the promise of prosperity and escape from hardships. The interactions between these groups shaped the nation’s demographics, culture, and politics, contributing to ongoing debates about identity, expansion, and labor.
