European Exploration Causes

Sep 1, 2025

Overview

This lecture covers the causes of European exploration, focusing on the social, economic, religious, and political changes in Europe that enabled and motivated overseas expansion.

Pre-Exploration Europe

  • Before 1450, Europe was politically decentralized and less powerful compared to Asian and Islamic empires.
  • The Black Death and the Little Ice Age caused population decline and agricultural hardship in Europe.
  • Warmer climate and improved farming techniques led to increased agricultural productivity and population growth.
  • Population increase revived European demand for Asian luxury goods.
  • The Renaissance sparked a cultural rebirth, further strengthening various European states.
  • Political unification created more stable and powerful European governments, paving the way for exploration.

Motives for Exploration: Gold, God, and Glory

  • Europeans sought new trade routes for Asian goods after the Ottoman Empire took control of Constantinople in 1453.
  • Portugal led maritime exploration, using trading-post empires around Africa and in the Indian Ocean.
  • Vasco da Gama reached India by sailing around Africa in 1498, establishing Portuguese presence in Asian trade.
  • Spain, unable to access the Indian Ocean, funded Columbus in 1492 to find a western route to Asia.
  • Columbus reached the Caribbean, believing he had arrived in Asia, leading to further Spanish colonization efforts.

Religious Motives

  • European society was dominated by Roman Catholic Christianity, which created cultural unity.
  • Corruption such as simony and the sale of indulgences led to criticism from reformers like Martin Luther.
  • In 1517, Luther's 95 Theses sparked the Protestant Reformation, splitting Christianity in Europe.
  • Competition between Catholic and Protestant states spilled into exploration, with each seeking to spread their faith.
  • Spain unified under Ferdinand and Isabella, completed the Reconquista in 1492, and enforced Catholic dominance through the Inquisition.
  • Religious rivalry fueled European efforts to convert indigenous populations.

Political Motives and Competition

  • Colonization became a way for European states to increase power and prestige (glory).
  • Spain initially dominated colonization in the Americas, prompting other nations to compete for colonies.
  • Emergence of nation-states intensified competition for overseas empire building.
  • The Treaty of Tordesillas (1494), mediated by the pope, divided the Americas between Spain and Portugal, ignoring indigenous peoples.
