Porque Fernando Isabel financiaron el viaje de Colón

Explanation:

During the Middle Ages, the Atlantic became for a good number of sailors the limit where they did not dare to enter with their boats. Still today, an accident on the coast of Galicia, in Spain, bears the name of Finisterre, that is, finis terrea, the end of the earth. Such fear, not infrequently fueled by legendary and unfounded tales, began to be slightly cracked at the end of the s. XIII when sailors from Castile, Catalonia, Mallorca, Portugal, Genoa and Venice dared to break that situation by launching in an isolated way to explore the ocean. From the s. XV also took place the colonization of the Atlantic archipelagos. The number of expeditions that took place in this regard is clearly revealing and it is no less so that the pioneers in this work were Spanish sailors. Thus in 1402 Juan de Bethencourt undertook the conquest of the Canary Islands. Bethencourt was Norman but depended on King Henry II of Castile and in this way the islands were linked to the Castilian Crown,

However, if the precursor was the Spanish role, extraordinarily outstanding was the one represented by Portugal. In 1419-20, Joao Gonçalvez Zarco and Tistrao Vaz arrived in Madeira starting a process that concluded with their occupation five years later. From 1432 to 1457 the Azores, previously explored by Italian sailors, were occupied by the Portuguese. In 1434 Gil Eanes reached Cape Bojador. In 1456, Cadamosto, a Venetian in the service of the Portuguese Crown, discovered Cape Verde, an enclave colonized by Diego Gomes from 1460.
