.
Manuel I did not share that opinion. Keeping his predecessor's plan, he went ahead to equip the ships and chose Vasco da Gama as the leader of this expedition and the captain of the armada. According to the original plan, John II had appointed his father,
Stephen da Gama, to head the armada; but by the time of implementing the plan, both were deceased.
The Portuguese were after spices, but they were very expensive because it was an inconvenience to trade. For example, it was dangerous and time consuming to travel by land from Europe to India.
As a result, King John II of Portugal established a plan for ships to explore the coast of Africa to see if India was navigable via around the cape, and through the Indian Ocean. King João II appointed
Bartolomeu Dias
Bartolomeu Dias ( – 29 May 1500) was a Portuguese mariner and explorer. In 1488, he became the first European navigator to round the Cape Agulhas, southern tip of Africa and to demonstrate that the most effective southward route for ships lies ...
, on October 10, 1486, to head an expedition to sail around the southern tip of Africa in the hope of finding a trade route to India.
Dias helped in the construction of the
''São Gabriel'' and its sister ship, the ''
São Rafael'' that were used by Vasco da Gama to sail past the Cape of Good Hope and continue to India.
One of the sailors, Bartolomeu Dias, passed the Cape of Good Hope and the southernmost point of Africa in 1488. He declared it possible to travel to India by going around Africa. The Portuguese were then able to make an immense profit by using their own ships to retrieve the spices.

This global expedition was launched on 8 July 1497. It concluded two years later with the entry of the ships back into the
River Tagus, bringing with them the good news that bestowed on Portugal a prestigious maritime position.

, the trade of Venice and Genoa reduced to a great degree. The advantage of the Portuguese to establish a sea route therefore virtually free of assault – however, covered in perils in the sea – showed itself rewarding and outlined a large income to the Portuguese Crown in the future. Portugal directly linked the spice-producing regions to their markets in Europe.

. Here their paths separated: Afonso de Paiva headed to Ethiopia and Pêro da Covilhã to India. None of the men returned, but the information needed by John II was brought back to the kingdom by intermediaries, and this information was used to garner the support to serve the possible epic maritime adventure that lay ahead.
The travel plan anticipated the safety issues of the route. For this, it was necessary to install trading posts along the way, and build fortresses. The mission was up to the captain of the
armada who was provided with many gifts and equipment to brave the seas and diplomatic credentials and perseverance to create links with unknown monarchs who eventually were found along the way.
But it was not in the reign of King John II that this project, which was already facing a strong opposition from the court, was initiated. It happened only in the time of his successor, Manuel I who incidentally did not share the general opinion about the sea routes being a good – if not the best – means to dominate trade with the East.

the kings were expected to be impressed with rich offerings. Goods presented by the Portuguese proved insufficient to impress the Zamorin and representatives of the Zamorin mocked their offers, while the Arab merchants already established there resisted the possibility of unwanted competition.
Vasco da Gama's perseverance made him nevertheless initiate negotiations between himself and the Zamorin, who was pleased with the letters of King Manuel I. Finally, Vasco da Gama managed to get an ambiguous letter of concession rights to trade.
The Portuguese eventually were able to sell their goods at a low price in order to acquire small amounts of spices and jewels to take to their kingdom. However the fleet eventually departed without warning after the Zamorin insisted that they left all their assets as collateral. Vasco da Gama kept his goods, but left a few Portuguese with orders to start a trading post.
