Magellan's Expedition Overview

Aug 3, 2025

Overview

This lecture covers Ferdinand Magellan's 1519-1522 expedition, the first successful circumnavigation of the globe, highlighting its motives, challenges, and achievements.

Background and Motives for Exploration

  • European exploration surged in the late 1400s due to demand for Far Eastern spices and increasing competition for trade routes.
  • Portugal dominated spice trade routes by 1518, prompting Spain to seek its own path to the Spice Islands.
  • Ferdinand Magellan, a skilled Portuguese navigator, proposed a western route to the Spice Islands to Spain’s King Charles I.

The Expedition Begins

  • In September 1519, Magellan set sail from Spain with 270 men and five ships.
  • The crew traded with indigenous peoples in Brazil for supplies before heading further south.

Mutiny and Struggles

  • Harsh winter conditions at Puerto San Julian led to a mutiny, which Magellan put down with executions and marooning the ringleaders.
  • The Santiago ship was wrecked and its crew rescued; San Antonio deserted and returned to Spain.

Discovery of the Strait and Pacific Crossing

  • Magellan discovered a 350-mile passage, now called the Strait of Magellan, leading to the Pacific Ocean.
  • The Pacific crossing lasted 99 days, with men suffering starvation and scurvy; 19 died before reaching Guam.

Reaching the Philippines and Magellan’s Death

  • After Guam, the expedition reached the Philippines and formed alliances with local rulers.
  • Magellan was killed in battle on Mactan Island, and the crew was ambushed by former allies.

Completing the Voyage

  • Survivors reached the Spice Islands after further hardship, trading everything for cloves.
  • The Trinidad ship was damaged and later captured; only the Victoria, led by Juan Sebastian Elcano, continued.
  • Victoria sailed home across the Indian and Atlantic Oceans, finally returning to Spain in September 1522 with just 18 surviving crew.

Achievements and Impact

  • Magellan’s expedition was the first to circle the globe, proving Earth’s roundness and vastness.
  • The feat was unmatched until Francis Drake repeated it 58 years later.

Key Terms & Definitions

  • Circumnavigation — sailing all the way around the world.
  • Carrack — a large sailing ship used in the 15th-17th centuries.
  • Scurvy — a disease caused by lack of vitamin C, common on long sea voyages.
