In early life, Christopher as a teen got a job on a merchant ship in 1451. He was at sea often till 1470. He then sailed across the Portuguese coast but french ships sunk his ship. He then drifted ashore to a nearby city and learned mathematics, astronomy, cartography, and navigation.
In 1492 Christopher asked for permission to take three ships west to find a quicker route to Asia. The king and queen let him. They gave him three ships the Nina, Pinta, Santa Maria.
He then set off on August 3 1492\ on his journey with three ships, and 89 men. He sailed for 61 days until he finally saw land. He thought the trip from Spain to Asia would be three thousand miles. But little did he know it was 12,000 miles.
