Columbus-historyII

There was a further element of key importance in the plans of Columbus, a closely held fact discovered, or otherwise learned, by Columbus: the trade winds. A brisk wind from the east, commonly called an "easterly", propelled Santa María, La Niña, and La Pinta for five weeks from the Canaries. To return to Crown of Castile eastward against this prevailing wind would have required several months of an arduous sailing technique, called beating, during which food and drinkable water would have been utterly exhausted. Columbus returned home by following prevailing winds northeastward from the southern zone of the North Atlantic to the middle latitudes of the North Atlantic, where prevailing winds are eastward (westerly) to the coastlines of Western Europe, where the winds curve southward towards the Iberian Peninsula.^[12] In fact, Columbus was wrong about degrees of longitude to be traversed and wrong about distance per degree, but he was right about a more vital fact: how to use the North Atlantic's great circular wind pattern, clockwise in direction, to get home.^[13][14]

Funding campaign

In 1485, Columbus presented his plans to John II, King of Portugal. He proposed the king equip three sturdy ships and grant Columbus one year's time to sail out into the Atlantic, search for a western route to the Orient, and return. Columbus also requested he be made "Great Admiral of the Ocean", appointed governor of any and all lands he discovered, and given one-tenth of all revenue from those lands. The king submitted the proposal to his experts, who rejected it. It was their considered opinion that Columbus's estimation of a travel distance of 2,400 miles (3,860 km) was, in fact, far too short.^[11]
In 1488 Columbus appealed to the court of Portugal once again, and once again John invited him to an audience. It also proved unsuccessful, in part because not long afterwards Bartholomeu Dias returned to Portugal following a successful rounding of the southern tip of Africa. With an eastern sea route now under its control, Portugal was no longer interested in trailblazing a western route to Asia.
Columbus travelled from Portugal to both Genoa and Venice, but he received encouragement from neither. Previously he had his brother sound out Henry VII of England, to see if the English monarch might not be more amenable to Columbus's proposal. After much carefully considered hesitation Henry's invitation came, too late. Columbus had already committed himself to Castile.

He had sought an audience from the monarchs Ferdinand II of Aragon and Isabella I of Castile, who had united the a lot of kingdoms in the Iberian Peninsula by marrying, and were ruling together. On 1 May 1486, permission having been granted, Columbus presented his plans to Queen Isabella, who, in turn, referred it to a committee. After the passing of much time, these savants of Castile and Aragon, like their counterparts in Portugal, reported back that Columbus had judged the distance to Asia much too short. They pronounced the idea impractical, and advised their Royal Highnesses to pass on the proposed venture.

However, to keep Columbus from taking his ideas elsewhere, and perhaps to keep their options open, the Catholic Monarchs gave him an annual allowance of 12,000 maravedis and in 1489 furnished him with a letter ordering all cities and towns under their domain to provide him food and lodging at no cost.^[15]
After continually lobbying at the Castilian and Aragonese court and two years of negotiations, he finally had success in 1492. Ferdinand and Isabella had just conquered Granada, the last Muslim stronghold on the Iberian peninsula, and they received Columbus in Córdoba, in the Alcázar castle. Isabella turned Columbus down on the advice of her confessor, and he was leaving town by mule in despair, when Ferdinand intervened. Isabella then sent a royal guard to fetch him and Ferdinand later claimed credit for being "the principal cause why those islands were discovered".
About half of the financing was to come from private Italian investors, whom Columbus had already lined up. Financially broke after the Granada campaign, the monarchs left it to the royal treasurer to shift funds among various royal accounts on behalf of the enterprise. Columbus was to be made "Admiral of the Seas" and would receive a portion of all profits. The terms were unusually generous, but as his son later wrote, the monarchs did not really expect him to return.
According to the contract that Columbus made with King Ferdinand and Queen Isabella, if Columbus discovered any new islands or mainland, he would receive many high rewards. In terms of power, he would be given the rank of Admiral of the Ocean Sea and appointed Viceroy and Governor of all the new lands. He had the right to nominate three persons, from whom the sovereigns would choose one, for any office in the new lands. He would be entitled to 10% of all the revenues from the new lands in perpetuity; this part was denied to him in the contract, although it was one of his demands. Additionally, he would also have the option of buying one-eighth interest in any commercial venture with the new lands and receive one-eighth of the profits.
Columbus was later arrested in 1500 and supplanted from these posts. After his death, Columbus's sons, Diego and Fernando, took legal action to enforce their father's contract. Many of the smears against Columbus were initiated by the Castilian crown during these lengthy court cases, known as the pleitos colombinos. The family had some success in their first litigation, as a judgment of 1511 confirmed Diego's position as Viceroy, but reduced his powers. Diego resumed litigation in 1512, which lasted until 1536, and further disputes continued until 1790.^[16]
