USA HISTORY

Detailed explanation-1: -During his lifetime, Columbus led a total of four expeditions to the “New World, ” exploring various Caribbean islands, the Gulf of Mexico, and the South and Central American mainlands, but he never accomplished his original goal-a western ocean route to the great cities of Asia.

Detailed explanation-2: -The explorer Christopher Columbus made four trips across the Atlantic Ocean from Spain: in 1492, 1493, 1498 and 1502. He was determined to find a direct water route west from Europe to Asia, but he never did. Instead, he stumbled upon the Americas.

Detailed explanation-3: -In response to the need for a new route to Asia, by the 1480s, Christopher and his brother Bartholomew had developed a plan to travel to the Indies (then construed roughly as all of southern and eastern Asia) by sailing directly west across what was believed to be the singular “Ocean Sea, ” the Atlantic Ocean.

Detailed explanation-4: -Amerigo Vespucci made about 3 to 4 voyages and landed on mainland America. He realised Columbus had not reached Asia but landed on a new continent. He named it “New World". Later, while preparing the new world map, a German cartographer re-named the New World as America, after Amerigo Vespucci.
