1.7 Causation in Period 1

Causation as a historical thinking skill

Causation means analyzing why events happened and what effects followed. In Period 1, historians examine causes (motives, conditions that led to European exploration and colonization) and effects (Columbian Exchange, conquest, demographic collapse). Distinguish immediate causes from long-term causes, and short-term effects from lasting long-term consequences that reshaped the Atlantic World.

Causes of European exploration and conquest

Multiple causes converged: technological innovations (caravels, navigation tools), desire for new trade routes to Asia after the fall of Constantinople, religious motivation (spreading Christianity, competing with Islam), and the drive for wealth and glory (gold, God, glory). Spain and Portugal's rivalry, plus advances in cartography, enabled sustained transoceanic voyages.

Effects on Native, European, and African societies

Contact triggered the Columbian Exchange, spreading crops, animals, and disease. Demographic collapse among Native peoples resulted largely from Old World pathogens (smallpox), reshaping labor systems and encouraging the rise of encomienda and eventually African slavery. Europe experienced economic growth from new wealth, while societies on both sides underwent lasting cultural transformation.

Key terms

Causation (historical thinking skill)

Analyzing the causes and effects of historical events, distinguishing immediate from long-term factors.

Cause of exploration: technology

Innovations like the caravel and improved navigation tools enabled long-distance ocean voyages.

Cause of exploration: religion

Desire to spread Christianity and compete with Islam motivated Spanish and Portuguese exploration.

Columbian Exchange

The transfer of plants, animals, people, and diseases between the Old and New Worlds after 1492.

Demographic collapse
