Answer:
After Christopher Columbus reached the shores of a new continent he was convinced that he reached shores of India. But many explorers doubt this. Among them was Amerigo Vespucci. He was convinced that Columbus reached a new continent, unknown to Europeans, not India. Therefore he traveled on his own across Atlantic Ocean in 1497. He reached the shores of todays Brazil. He realized that he reached the shores of a territory unknown to Europeans, which he named New World. In respect to Vespucci's achievement the whole continent was named after him - America.
