Following the American Conquest of California, the community on the rancho incorporated as a city in 1854. The city grew significantly in the late 19th century as a commercial hub at the crossroads between Southern California and the American Southwest. Today, San Bernardino is an important hub for the Inland Empire and Southern California.
