1.3 European Exploration in the Americas

Motives for European exploration

Europeans sought new trade routes to Asia and were driven by the '3 G's': God, Gold, and Glory. Technological advances like the caravel, astrolabe, and compass, plus growing state power, enabled long-distance voyages. Spain and Portugal led early exploration, followed by France, England, and the Netherlands seeking wealth and religious conversion.

The Columbian Exchange

Contact between the Eastern and Western Hemispheres triggered the Columbian Exchange — the transfer of plants, animals, diseases, and people. New World crops (maize, potatoes) boosted European populations; European livestock and crops transformed American ecosystems. Devastatingly, European diseases like smallpox killed up to 90% of some Native populations, who had no immunity.

Spanish colonization models

Spain established an empire built on conquest and exploitation, using the encomienda system to force Native labor for mining and agriculture. The Columbian Exchange and Spanish demand for labor led to the rise of the African slave trade as Native populations declined. Spanish conquistadors like Cortés and Pizarro conquered the Aztec and Inca empires.
