The ranch was to be one of the Mission's principle rancherias, and the most distant, and it occupied most of today's San Gorgonio Pass area. With the signing of the Treaty of Cordoba in 1821, Mexico gained its independence from Spain, but the San Gabriel Mission near what is now Los Angeles, California, continued to expand, and established Rancho San Gorgonio in 1824.

Serrano was mayordomo of San Antonio de Pala Asistencia for the Mission of San Luis Rey. In 1819, the Mission granted Leandro Serrano permission to occupy the land for the purpose of grazing and farming, and Serrano established Rancho Temescal. The first European settlement in the county was a Mission San Luis Rey de Francia estancia or farm at the Luiseño village of Temescal. The Cahuilla territory is to the east and north of the Luiseño in the inland valleys, in the Santa Rosa and San Jacinto Mountains and the desert of the Salton Sink. The Luiseño territory includes the Aguanga and Temecula Basins, Elsinore Trough and eastern Santa Ana Mountains and southward into San Diego County. The indigenous peoples of what is now Riverside County are the Luiseño, Cupeño and Cahuilla Indians. The city, founded in 1870, received its name for its location beside the Santa Ana River. When Riverside County was formed in 1893 it was named for the city of Riverside, the county seat.
