Exploration
In the Pacific Ocean, Jorge de Menezes (c. 1498–?), discovered Papua New Guinea. García Jofre de Loaísa (1490–1526), discovered the Marshall Islands. Explorations of the Americas began with the initial discovery of America by Christopher Columbus (1451–1506), who led a Castilian (Spanish) expedition across the Atlantic, discovering America. After the discovery of America by Columbus, a number of important expeditions were sent out to explore the Western Hemisphere. This included Juan Ponce de León (1474–1521), who discovered and mapped the coast of Florida; Vasco Núñez de Balboa (c. 1475–1519), who was the first European to view the Pacific Ocean from American shores (after crossing the Isthmus of Panama) confirming that America was a separate continent from Asia; Aleixo Garcia (14?–1527), who explored the territories of present-day southern Brazil, Paraguay and Bolivia, crossing the Chaco and reaching the Andes (near Sucre).
Maritime history
John Cabot was a Genoese navigator and explorer commonly credited as one of the first early modern Europeans to land on the North American mainland aboard the in 1497. Sebastian Cabot was an Italian explorer and may have sailed with his father John Cabot in May 1497. John Cabot and perhaps Sebastian, sailing from Bristol, took their small fleet along the coasts of a "New Found Land". There is much controversy over where exactly Cabot landed, but two likely locations that are often suggested are Nova Scotia and Newfoundland. Cabot and his crew (including perhaps Sebastian) mistook this place for China, without finding the passage to the east they were looking for. Some scholars maintain that the name America comes from Richard Amerik, a Bristol merchant and customs officer, who is claimed on very slender evidence to have helped finance the Cabot voyages.
