In the 18th century, the land of Rancho Cucamonga was incorporated into the Mission System under Father Junipero Serra and, after many decades of struggle for control of the region, it eventually came under the control of the governor of Mexico. It was during this time period that Spain's control of much of the region weakened and Mexico won independence, expanding into Baja California and Southern California. In 1839, a large area called Cucamonga was granted to a Spanish native of Los Angeles and smuggler who developed California's first winery on the land. In 1846, American forces entered California and it became a state in 1850 but Southern California was at the time described as a "random collection of adobes." By 1887, irrigation tunnels were created and the Santa Fe Railroad was extended into the region.
Rancho Cucamonga was formed in 1977 when the unincorporated communities of Cucamonga, Alta Loma, and Etiwanda voted to incorporate together.
