Pre-Colonial & Colonial Era
to 1763Pre-Columbian Societies
Before European contact, North America was home to hundreds of distinct Indigenous cultures organized around geography and available resources:
- Eastern Woodlands: Iroquois Confederacy (Haudenosaunee) — 5 (later 6) nations with a sophisticated democratic confederation that may have influenced the U.S. Constitution; matrilineal clans
- Southwest: Pueblo peoples (Hopi, Zuni) — adobe villages, advanced irrigation agriculture, corn-based culture
- Great Plains: Semi-nomadic buffalo hunters; nomadism increased after Spanish introduced horses in 1500s
- Pacific Northwest: Salmon-based economies; elaborate totem and potlatch traditions
- Mississippian culture: Large mound-building civilization centered at Cahokia (near modern St. Louis); declined before European contact
European Contact & Exploration
- Columbus (1492): Opened sustained contact between Europe and the Americas; sailed for Spain
- Columbian Exchange: Transfer of plants (corn, potatoes, tobacco), animals (horses, cattle), diseases (smallpox, measles), and people between Old and New Worlds. Diseases devastated Indigenous populations — estimates of 50–90% mortality in some regions
- Spanish Conquistadors: Hernán Cortés conquered the Aztec Empire (1521); Francisco Pizarro conquered the Inca (1532). Encomienda system granted colonists Indigenous labor.
- Spanish colonial model: Missions, presidios, ranchos; intermarriage common; created mestizo society; focused in Mexico, Caribbean, Southwest, Florida
- French colonization: Quebec (1608); focused on fur trade; allied with Indigenous nations (especially Huron/Algonquin); less settlement-oriented than England or Spain
- Dutch: New Netherland (Hudson River valley); founded New Amsterdam (later New York); primarily commercial enterprise
English Colonial Regions
New England (Massachusetts, Connecticut, Rhode Island, New Hampshire):
- Puritans sought to build a "city upon a hill" — a godly model society
- Plymouth Colony (1620) — Pilgrims, Mayflower Compact (first self-governance document in English America)
- Massachusetts Bay Colony (1630) — John Winthrop; theocratic government; expelled dissenters
- Roger Williams founded Rhode Island (1636) — religious tolerance, separation of church and state
- Anne Hutchinson — Antinomian Controversy; challenged Puritan clergy authority; banished to Rhode Island
- Economy: subsistence farming, fishing, shipbuilding, trade; family farms; town meeting democracy
Middle Colonies (New York, Pennsylvania, New Jersey, Delaware):
- Most diverse — English, Dutch, German, Scotch-Irish, Quakers, Catholics, Jews
- Pennsylvania: William Penn's "Holy Experiment" — Quaker colony, religious freedom, fair treatment of Lenape
- Breadbasket colonies — wheat, grain exports; Philadelphia became largest colonial city
Southern Colonies (Virginia, Maryland, Carolinas, Georgia):
- Virginia (1607, Jamestown) — first permanent English settlement; tobacco became profitable cash crop by 1612 (John Rolfe)
- Indentured servitude → chattel slavery: initially relied on white indentured servants; Bacon's Rebellion (1676) accelerated shift to enslaved African labor
- Headright system: 50 acres per colonist brought to Virginia; created large planter class
- Maryland: founded by Lord Baltimore as Catholic refuge; Toleration Act (1649)
- Carolina split into North/South (1712); South Carolina's rice/indigo economy heavily dependent on enslaved Africans — majority Black colony by 1700s

Colonial Society & Economy
- Mercantilism: British economic theory — colonies exist to enrich the mother country; Navigation Acts (1651+) required colonial trade through British ships and ports
- Salutary neglect: British largely ignored colonial violations of trade laws (roughly 1690s–1763); colonies developed significant self-governance habits
- Colonial assemblies: Virginia House of Burgesses (1619) — first representative assembly in English America; all colonies had elected lower houses controlling taxation

- Confederacy: Jefferson Davis, president; Alexander Stephens, VP (Cornerstone Speech — declared slavery the "cornerstone" of the Confederacy)
- Border states: Maryland, Kentucky, Missouri, Delaware — slave states that did not secede; Lincoln used careful political management to keep them in Union
- Advantages — Union: Larger population (~22M vs. ~9M incl. ~3.5M enslaved), industrial capacity, railroad network, naval power, established government
- Advantages — Confederacy: Defensive war on home territory, superior military leadership (Lee, Jackson), high morale, cotton diplomacy hopes
Key Military Events
- Bull Run (1861): First major battle; Confederate victory; shattered Northern illusion of quick war
- Monitor vs. Virginia (1862): First battle of ironclad warships; revolutionized naval warfare
- Antietam (Sept. 1862): Bloodiest single day in U.S. history (~23,000 casualties); tactical draw but strategic Union victory — stopped Lee's Maryland invasion; gave Lincoln a platform to issue Emancipation Proclamation

- 13th Amendment (1865): Abolished slavery throughout the United States
- Conscription: Both sides instituted drafts; Union's $300 commutation fee sparked Draft Riots in New York City (1863) — largely Irish immigrants attacked Black New Yorkers
- Women's roles: Women managed farms and businesses; served as nurses (Clara Barton, Dorothea Dix); some spied; war expanded women's public roles
- Economic impact: Union financed war with income tax (first in U.S. history), greenbacks (paper money), bonds; National Banking Act (1863); Southern economy devastated
Reconstruction
1865–1877Plans & Amendments

- Johnson's Reconstruction: Even more lenient; pardoned most Confederates; allowed Southern states to pass Black Codes (laws restricting freedpeople's rights); Congressional Republicans furious
- Reconstruction Amendments:
- 13th (1865): Abolished slavery
- 14th (1868): Citizenship to all born in U.S.; equal protection; due process; basis of modern civil rights law
- 15th (1869): Black male suffrage — cannot deny vote based on race, color, or previous servitude

- Impeachment of Johnson (1868): Violated Tenure of Office Act; House impeached; Senate acquitted by one vote
- Black political participation: ~2,000 Black officeholders during Reconstruction; Hiram Revels and Blanche Bruce — first Black U.S. senators; 16 Black congressmen
- Sharecropping: System replacing slavery — freedpeople farmed white-owned land for share of crop; perpetual debt cycle; little better than slavery in practice
- Ku Klux Klan: Founded 1865; terrorized Black voters, officeholders, and Republican allies; Enforcement Acts (1870–71) — federal crackdown; temporarily suppressed KKK
- Compromise of 1877: Disputed presidential election (Hayes vs. Tilden); Republicans agreed to withdraw federal troops from South in exchange for Hayes presidency; ended Reconstruction; opened era of Jim Crow
