Question

What was happening in america in 1497-1502?

Answer 1

An important expedition to the east leaves Lisbon in 1497. In July Vasco da Gama sails south in his flagship, the St Gabriel, accompanied by three other vessels. In late November the little fleet rounds the Cape of Good Hope. Soon they are further up the east coast of Africa than Dias ventured ten years earler. In March they reach Mozambique. They are excited to find Arab vessels in the harbour, trading in gold, silver and spices, and to hear that Prester John is alive and well, living somewhere inland. 

In the well-established Portuguese tradition, da Gama has on board a good supply of stone pillars. He sets one up in each new territory, to claim it for his king. 
 









The real prize lies ahead, a dangerous journey away, across the Indian Ocean. At Malindi, on the coast of Kenya, a pilot is found who knows the route northeast to Calicut, an important trading centre in southern India. 

After twenty-three days Calicut is safely reached. Da Gama is welcomed by the local Hindu ruler, who must surely wonder why his guest is so keen to erect a stone pillar. 
 







Da Gama spends three months in Calicut before sailing back to Africa. Adverse winds extend the crossing this time from three weeks to three months, and before the African coast is reached many of the crew die of scurvy -- a first glimpse of one of the problems of ocean travel. 

Da Gama arrives back in Lisbon in September 1499, more than two years after his departure. He is richly rewarded by the king, Manuel I, with honours, money and land. He has not managed to conclude a treaty with the ruler of Calicut. But he has proved that trade with the east by sea is possible. Manuel moves quickly to seize the opportunity. 
 







Six months later, in March 1500, the king sends Pedro Cabral on the same journey. He takes such a curving westerly route through the Atlantic that he chances upon the coast of Brazil (an accident with its own significant results). This time a warehouse is established in Calicut, but the Portuguese left there to run it are murdered. To avenge this act, da Gama is sent east again in 1502. He bombards Calicut from mortars aboard his ship. With this clear evidence of Portuguese power a treaty becomes available. 

These events, east and west in India and Brazil, provide the basis of the Portuguese empire, with all its rich opportunities for future traders and missionaries.
