The man who was thought to be the discoverer of America was born
in 1451 in Italy. His name was Christopher Columbus. At that time the life of a
sailor was full of adventure and danger, so Columbus had many exciting
experiences. Knowing that the earth was round, he decided to
reach India by sailing to the west. It was very difficult for him to
organise his expedition as nobody wanted to help him.
