## Etymology

The name Susticacán is believed to be derived from the Tarascan etsosticacán, meaning "place of the strong canyon." The modified Susticacán is a result of changing dialects of the time.

## History

The first indigenous inhabitants of the region, a Zacatecos band of Chichimeca, were not subdued by force from Spanish conquistadors, but rather became integrated into the government of New Spain with the establishment of the Catholic faith. The town of Santo Tomás de Etsosticacán was founded in 1562 by local indigenous peoples under the leadership of Andrés Melchor. The Spaniards originally permitted the natives to live under their own laws with Melchor as their first leader.
The original land allocation was imprecise and in 1597 the area was reduced to fewer than 800 hectares. In the 17th century, this led to the acquisition of additional land due to social organization and the collective efforts of residents, including the work of religious congregations such as the Brotherhood of the Virgin of the Assumption (also called La Virgen del Rayo).
In 1648, Juan Antonio, the indigenous steward of the Brotherhood, purchased a large tract of land the mountains and with his family founded the ranch Chiquihuitillo, a community in the municipality of Susticacán known today as El Chiquihuite. In the years that followed, the boundaries of the municipality continued to expand with the formation of additional communities into the late 18th century.
The town later switched its patronage first to St. Peter of Alcántara, and then in 1677 to the Virgin of the Immaculate Conception; a church dedicated to her was built in 1704.
After Mexican independence, Susticacán became part of the partido or district of Jerez. A municipal government (junta municipal) was established for the town on 29 October 1833. After partidos were abolished in 1916, Susticacán became an independent municipality. A dirt road connecting Susticacán to Jerez was built in 1960; Susticacán Reservoir was built from 1962 to 1965; and the municipal seat was electrified in 1968.

## Administration

The municipal government of Susticacán comprises a president, a councillor (Spanish: síndico), and seven trustees (regidores), four elected by relative majority and three by proportional representation. The current president of the municipality is Fabiola Rodríguez Saldívar.
