1790s–1820s
1790s–1820s: The Early Republic
The United States established its governing institutions, survived its first partisan battles, and began expanding westward. The Louisiana Purchase doubled national territory. The Era of Good Feelings gave way to new political divisions. A distinctly American national identity began to take shape.
Why This Era Matters
The early republic tested whether constitutional democracy could survive. The peaceful transfer of power, the emergence of political parties, and early debates over federal power and states' rights set patterns that shaped American politics for two centuries.
