Presidio of Tubac

 (1752-1776, 1787-1820) - A Spanish Presidio established in 1752 in Pimeria Alta (place of the upper Pimas) in present-day Santa Cruz County, Arizona. Abandoned in 1776. Reactivated in 1787. Also known as Presidio San Ignacio de Tubac and later as Camp Tubac.

The Spanish Period (1752-1821)
A Spanish Presidio established in 1752 as the most northern Presidio in Pimeria Alta (place of the upper Pimas). The Presidio was situated on what became the road to California and San Francisco. Frequent Apache raids caused the Presidio to be abandoned in 1776 in favor of the Presidio of Tucson. The Presidio was regarrisoned in 1787. The southern Arizona presidios included:

The Mexican Period (1822-1853)
The Mexican War of Independence brought the Presidio and the mission system under the control of the new Mexican Government which issued an order in 1833 to secularize the presidios and the missions. Control of Presidio and mission lands was eventually taken away from the church and distributed to private persons. The southern part of Arizona remained under Mexican control after the Mexican War with the United States and in 1853 the Gadsden Purchase gave the U.S. Government control over all of present-day Arizona including the presidios and missions.

U.S. Civil War (1861-1862)
Camp Tubac was established near the ruins of the old presidio on 20 Jul 1862 by troops of the 1st U.S. Cavalry and 2nd U.S. Cavalry. The supply camp was abandoned in August 1865 at the end of the war. It was reoccupied from 1866 to 1868 and then abandoned.
