On August 31, 1731, Leal was elected
alcalde (mayor) and
regidor of the city. Since departing from
Tenerife, he had been the group's leader. Once the Canarian people established themselves in the city, Leal found they had problems, including frequent clashes with the
Franciscan missionaries of San Antonio and the soldiers stationed at the
presidio. The Franciscans were opposed to the Canarians settling in the middle of an area where they had already established their domain and that they regarded as belonging to them. Given these considerations and his investment in his own decision to settle in Texas, Leal traveled from San Antonio to
Mexico to speak to the viceroy and request that the appropriate orders be given to the Captain of the presidio, Almazan, and thus ensure that the
Cabildo (council) constituted by the new settlers in Texas had the greater power in the matter and the Canarian settlers would be enabled to succeed in their mission. He also requested necessary instructions on how to administer the council. The viceroy, again assisted by Brigadier Rivera, sent clear orders to the captain of the presidio to recognize and respect the will of the council. Leal succeeded in establishing the new colony and the city was populated with new families. In 1735, Leal was appointed as town councilman, and soon after was appointed to a life term as
alcalde. Leal was not considered either tolerant or judicious by many among the military, the clergy, and the settlers themselves, and soon gained their general contempt. Consequently, his second term as mayor lasted only a year and he was replaced again by Antonio de los Santos. , main Plaza, Cathedral, and Court House of colonial San Antonio Although Leal's administration seems to have been successful, he had clashes with other Canarians in Texas. The first of the Canarians with whom he had problems was Mayor
Alguacil Vicente Álvarez Travieso, from whom he was to reclaim a loan in court when they arrived in Coahuila. Leal had made a loan to Travieso in San Luis Potosí, and Travieso had not repaid him by the deadline. This circumstance and the distribution of land lots (Juan Leal had chosen the last one and therefore the worst one) in the city was a trigger for a series of lawsuits and claims against other families like the Traviesos, the Curvelos, the Padróns, and the Santos. These events occurred between 1732 and 1735. == Later years ==
