"Jalostotitlán" means "Land Of Sandy Caves" in Nahuatl.
In 1164, the residents of the area (mostly from the Tecuexe and Caxcan tribes) resisted Aztec advances, who had just settled in nearby Teocaltiche for a period of 40 years before moving on to Tenochtitlán.
After a series of rebellions, the area was placed under the Spanish crown in 1541. The town of Jalostotitlán was founded by Fray Miguel de Bologna in 1544.
After the Mexican War of Independence, Jalostotitlán gained the status of a town in 1838. The municipality of Jalostotitlán was created on 21 May 1872.
Jalostotitlan is the location of sites associated with canonized Mexican Catholic priests Toribio Romo Gonzalez and Pedro Esqueda Ramírez, who were murdered by federal troops during the Cristero War or La Cristiada
Jalostotitlán was elevated to city status on 1 September 1970 and made the seat of the municipality.
Jalostotitlán is the birthplace of famed General José María González de Hermosillo, who fought in the Mexican War of Independence. The city of Hermosillo, Sonora is named in his honor. It is also the birthplace of famed poet Alfredo R. Plascencia Jáuregui.
The population of the municipality of Jalostotitlán totaled 53,256 inhabitants according to the 2000 census. Of these, 20,201 reside in the municipal seat. Similar to the rest of the Los Altos region, Jalostotitlán did not retain a large indigenous population. Only two-tenths of one percent of inhabitants speak an indigenous language according to the census.
The main activities in the municipality are agriculture, cattle-farming and the services industry. In the past 15 years Jalostotitlán has become a relevant manufacturing center, producing shoes, leather goods and dairy products.
Annual Fiestas in Jalostotitlan 
There are two fiestas that are celebrated in Jalostotitlán once a year. The "Carnaval" that is held early to mid-February and the other in August (August 1–15) is the "Fiestas De La Virgen De La Asuncion" or "La Quincena", a religious festival. During the Carnaval there are lots of activities and events during the whole week. Carnaval has concerts, also known as "palenques". Bullfighting, cock fighting and parades are part of the activities. "Terrazas" or outdoor bars are found in the plaza accompanied with live bandas and mariachi music. The Fiestas in August include mariachi music, Caxcan native dances, allegoric and big-rig truck parades and at night a "Castillo" or tower with fireworks every night. People from United States (mostly from California and other western states) go there to visit families during these festivals.
