Unit 1 Review: The World Europeans Entered, 1491–1607

Unit 1 review: key dates, the facts that explain how power shifted after 1492, practice questions, and a source-based SAQ.

A Continent Changes After 1492

Before sustained European colonization, North America contained many societies whose economies and political systems were shaped by local environments and long-distance exchange. Contact after 1492 linked the Americas, Europe, and Africa. Disease produced catastrophic demographic losses in many Indigenous communities, but conquest also depended on diplomacy, political rivalry, warfare, and labor systems. Spanish colonization developed strong systems of conquest, mission activity, coerced labor, and social hierarchy. French and Dutch ventures more often depended on smaller settler populations and trade alliances. Native nations responded through diplomacy, selective alliance, adaptation, migration, and resistance.

Use These Facts to Explain How Power Shifted

  • Cahokia: large-scale Indigenous political and trade organization existed before European settlement.
  • Irrigation in the Southwest: environment shaped economic organization.
  • Tlaxcalan alliance: Spanish conquest depended on Indigenous politics as well as European power.
  • Encomienda: conquest became a labor and governing system after military victory.
  • French/Native trade alliances: European empires used different settlement and economic strategies.
  • Atlantic slavery: European commodity production connected labor coercion to a growing transatlantic system.

Claims That Flatten the Period

Do not treat Native societies as one culture. Do not call disease the only cause of conquest. Do not call 1619 the beginning of slavery in the Americas. Do not assume an old European map is a complete map of Native political geography.
