4.15 Continuity and Change in Period 4

What Stayed the Same

Despite big changes, several themes from earlier periods continued: the U.S. remained a republic wrestling with the meaning of democracy, slavery persisted and expanded westward, regional identities (North, South, West) stayed distinct, and the federal-state power debate continued from the Constitutional era through nullification and states' rights arguments.

Major Changes 1800-1848

Key shifts included the rise of market economy and industrialization, expansion of democracy (universal white male suffrage), westward expansion via Louisiana Purchase and Manifest Destiny, growth of political parties (Federalists/Democratic-Republicans to Democrats/Whigs), and social reform movements (abolition, temperance, women's rights) fueled by the Second Great Awakening.

Connecting Threads

The market revolution transformed both economy and society, deepening sectional divides over slavery and tariffs while linking regions through transportation (canals, railroads). Reform and religious revival reshaped culture even as older debates over federal power and sectionalism, first seen in Period 3, intensified — setting the stage for Period 5's crisis.
