Answer:
Christopher Columbus, the son of a wool merchant, was born in Genoa in about 1451. (History.com, 2013) When he was still a teenager, he got a job on a merchant ship. Until 1470 Christopher Columbus remained on the see, when French merchant ships that were owned and officered by private individuals using government permission for use in war attacked his ship as it sailed north along the coast of Portuguese. The boat sank, but the young Columbus floating on a scrap of wood from the sunken ship made his way to Lisbon, where he studied four subjects which were mathematics, astronomy, cartography and navigation.
During two centuries which were the 15th and 16th centuries, several leaders of European nations were sponsoring expeditions abroad in the hope that explorers would find great wealth and very great extent of undiscovered lands. In the so called “Age of Discovery” the Portuguese were the first people to participate in it. About 1420 was when it started of small Portuguese ships known as caravels zipped along the African coast and which were carrying spices, gold, slaves and other goods from Asia and Africa to Europe.
At the end of the first of the two centuries which was the 15th century, it was nearly no way to Europe on land. The only route was long and arduous, which you could have encounters with hostile armies who were very difficult to avoid. Explorers from Portugal solved the land round and hostile army problems by taking to the sea which they ended up sailing to the south along the West African coast also around the Cape of Good Hope.
