After the Spanish founded Mission San Gabriel in 1771, the Chino Hills area was used as spillover grazing pasture by mission cattle and horses. In 1841, the area was part of a land concession given to Antonio Maria Lugo, and became known as Rancho Santa Ana del Chino. In 1846, the Battle of Chino, a notable battle of the Mexican-American War was fought on a battlefield in Chino Hills. After Mexico ceded California to the United States in 1848, the land continued to be used for cattle ranching.[citation needed]
