Between 1405 and 1433, the Chinese admiral Zheng He led seven great voyages across the Indian Ocean. His biggest ships were among the largest wooden ships ever built, and his fleets carried thousands of sailors to India, Arabia and the east coast of Africa. Then China's rulers ended the voyages and turned inward.
Key idea
The voyages joined the two halves of the world. Plants, animals and people crossed the ocean in both directions: the Columbian Exchange. Europe, Africa and Asia got corn, potatoes, tomatoes and chocolate; the Americas got horses, cattle, wheat and sugarcane. But Europeans also brought sicknesses such as smallpox, which killed a great many of the people of the Americas.
| From the Americas | To the Americas |
|---|---|
| corn, potatoes, tomatoes | wheat, rice, sugarcane |
| peppers, peanuts, chocolate | horses, cattle, pigs, sheep |
| turkeys | diseases such as smallpox and measles |
Worked example: Around the world
- Magellan was killed in a battle in the Philippines in 1521.
- Juan Sebastián Elcano led the last ship home.
Answer: No. His crew, led by Elcano, finished it.
Common mistake
Try it at home
- On a globe, use a piece of string to trace Columbus's route from Spain to the Caribbean, and da Gama's from Portugal around Africa to India. Which is longer?
- Find three foods in your kitchen that came from the Americas, and three that came to the Americas.
