In 1837, the Mexican government built Presidio de Calabasas to protect the area. In 1844, Mission Calabasas and its lands were sold at auction to the brother-in-law of Sonoran governor Manuel María Gándara. Gandara established a rancho at the old mission stocked with 6,000 cattle. The 1854 Gadsden Purchase, of land by the U.S. from México, included this area in New Mexico Territory. Mexican Army soldiers, in the Tucson garrison to protect the citizens from Apaches, withdrew from the Gadsden Purchase territory early in 1856. With their withdrawal the Gándara ranch came to an end.
