Christopher Columbus was born in Genoa, Italy. He was the oldest of five children in his family. His father was a wool weaver. He helped his father with the weaving, but he always wanted to sail the seas.

He didn’t get to school very much, but he learned to read and write Spanish during his travels. He also taught himself Latin because all the geography books were written in Latin. Some people thought he was trying to prove the world was round, but this is not true. He wanted to find a short way to get to the Indies by ship.

He was a Christian and wanted to tell the story of Christ to the people he would find in the far-away lands. He also wanted wealth for himself and for Spain, and he wanted to be famous. He tried for eight years to get King Ferdinand and Queen Isabella to supply him with ships and money.

They left Spain on August 3, 1492 and sailed toward the west. After many days, the sailors had covered a long distance on the sea and were ready to turn around for home when they saw land, an island Columbus named San Salvador. He thought he had found the Indies and called the people he saw there “Indians”. When they got to Cuba, he thought he was in Japan. The world was a lot larger than he thought.

On Christmas Eve, the Santa Maria was wrecked near Haiti. Columbus built a fort(城堡) and left 40 men to hunt for gold. Then he returned to Spain on the Nina. The people of Spain welcomed him as a hero. He made three more voyages across the ocean. His 13-year-old son, Ferdinand, went with him on the fourth voyage.

Columbus did not become rich as he had hoped. At the end of his life he only had a pension the king and the queen had given him because he was the first to reach the New World. He spent the last few months of his life in bed because of the pain of arthritis(关节炎). Columbus not only discovered a New World, but he led the way for other explorers.
