Aug 18, 2025

Overview

This lecture explains the causes and early events of European exploration in the Americas, focusing on Portugal, Spain, and the consequences of Columbus’s journey.

Causes of European Exploration

  • Europe's population recovered after the Black Plague, leading to renewed interest in trade and expansion.
  • Centralized governments under powerful monarchs provided political stability for overseas ventures.
  • Wealthy European upper classes desired luxury goods from Asia, increasing demand for new trade routes.
  • Muslim control over land-based trade routes in Afro-Eurasia pushed Europeans to seek sea routes to Asia.

Portugal’s Role in Exploration

  • Portugal, led by Prince Henry the Navigator, sought a sea route to Asia by sailing around Africa.
  • Portuguese established a "trading post empire" along Africa’s coast and dominated Indian Ocean trade.
  • They used caravels (nimble trade ships), maritime charts, astronomical tables, the astrolabe, and the sternpost rudder for improved navigation.

Spanish Exploration and Columbus

  • Spain, unified under Isabella and Ferdinand, wanted to compete with Portugal economically and spread Christianity.
  • Christopher Columbus received Spanish sponsorship to find a westward sea route to Asia.
  • In 1492, Columbus landed in the Caribbean (San Salvador), mistaking it for the East Indies and calling the natives "Indians."
  • Columbus returned to Spain with gold and enslaved natives, inciting further Spanish exploration in the Americas.

Outcomes and Impact

  • It became clear Columbus had not found Asia, but his voyage initiated the Columbian Exchange—a major global transformation.
