How a California frontier town evolved from a mission outpost into a global hub.

In short: San Bernardino began as a Spanish mission chapel in 1810, but its identity shifted rapidly. From a planned Mormon colony and a gold rush trading post to the birthplace of the modern fast-food industry, this Inland Empire city has constantly reinvented itself while navigating seismic shifts in culture and economy.

The San Bernardino Valley was long home to the Tongva people, with the village of Kaawchama serving as a vital trade center along the Santa Ana River. Spanish missionaries arrived in 1810, establishing a supply station named for Bernardino of Siena. This site, known as the Guachama Rancheria, was later destroyed by earthquakes and local tribal resistance, only to be rebuilt and eventually incorporated into the Rancho San Bernardino land grant awarded to José del Carmen Lugo in 1842.

The modern city took shape after the American Conquest of California. In 1851, pioneers from the Church of Jesus Christ of Latter-day Saints established a colony based on the City of Zion urban plan. Although most Mormons were recalled to Utah in 1857 due to the Utah War, the town persisted, evolving into a rugged frontier settlement. The 1860s gold rush in the nearby mountains further transformed the area into a critical commercial crossroads, supported by new roads like the Bradshaw Trail.

Throughout the 20th century, the city became a crucible for American innovation. It was the site where Richard and Maurice McDonald founded their original restaurant concept in 1940, and where Glen Bell later developed the foundation for Taco Bell after observing local culinary practices. Despite facing significant challenges, including a major municipal bankruptcy filing in 2012 and the tragic 2015 terrorist attack, San Bernardino remains a pivotal hub for the Inland Empire, anchored by its role in regional logistics, education, and its unique status as a gateway to the San Bernardino Mountains.
