By the 1730s, the Karankawa and other native tribes of the Texas area were viewed by the Spanish as the primary obstacle to control of northern New Spain. In 1749, Jose Escandon was made governor and representative of the viceroy, appointed to conquer and settle northern Mexico and the region of Texas and to map, survey, and acquaint himself with the area and with the natives. He recommended that the mission of La Bahía should be moved because of native hostility and the unfavorable climate.
