The first, in 1517, was given by Francisco Hernandez de Cordoba, who is known as the "discoverer of Yucatan." This first issue was pretty rough, for the inhabitants attacked the expedition three times in Ekab, Chakan Putumayo and the peninsula of Florida. Disappointed by the results, Velazquez organized in 1518 and sent Juan de Grijalva and captain of the second expedition, in which the priest Juan Diaz served as chaplain and wrote a chronicle of the trip itinerary. The expedition, which was intended to towns or garrisons, was not successful. Velasquez, irritated by the continuing failures, organized a third expedition in 1519, the conquest. The third issue a Velazquez appointed Cortes Monroy Pizarro Altamirano (full name of the conqueror) for this journey in which both the costs involved, however, soon had disagreements and Velasquez, who had virtually lost control of the issue, tried stop sending letters of complaint to the king of Spain, Charles I of Habsburg. But Cortes, more cunning, earned the favor of his subordinates and far from stopping the issue, went on to recruit volunteers to collect a total of 550 Spanish, 16 horses, 14 cannons, 32 crossbows, 13 guns and 200 auxiliaries (including Island natives and black slaves). a Meanwhile in Spain, King Charles I was signed on November 13, 1518, the document authorizing Velazquez to make the expedition. It seemed to be the end of Cortes, but the Governor of Cuba, which obviously could not know the opinion in his favor, lost time sent several letters, one addressed to itself very threatening Cortes, and the other to Juan Velazquez de Leon, Diego de Ordaz, and the mayor of Trinidad, Francisco Verdugo, asking them to entertain out of the issue or in any case, the arrest of the leader.
