Californio (plural Californios) is a term used to designate a Hispanic Californian, especially those descended from Spanish and Mexican settlers of the 17th through 19th centuries. California's Spanish-speaking community has resided there since 1683 and is made up of varying Spanish and Mexican origins, including criollos, Mestizos, Indigenous Californian peoples, and small numbers of Mulatos. Alongside the Tejanos of Texas and Neomexicanos of New Mexico and Colorado, Californios are part of the larger Spanish-American/Mexican-American/Hispano community of the United States, which has inhabited the American Southwest and the West Coast since the 16th century. Some may also identify as Chicanos, a term that came about in the 1960s.
The term Californio (historical, regional Spanish for 'Californian') was originally applied by and to the Spanish-speaking residents of Las Californias during the periods of Spanish California and Mexican California, between 1683 and 1848. The first Californios were the children of the early Spanish military expeditions into northern reaches of the Californias. They established the presidios and subsequently enabled the foundation of the California mission system.
Later, the primary cultural focus of the Californio population became the Vaquero tradition practiced by the landed gentry, who received large land grants and created the Rancho system. In the 1820s-40s, American and European settlers increasingly migrated to Mexican California. Many married Californio women and became Mexican citizens, learning Spanish and often converting to Catholicism, the state religion. They are often also considered Californios, for their adherence to Californio language and culture.
In 2017 there were 11.9 million Hispanic/Mexican American/Hispanos in California (30% of California's population). They make up the largest group of the 15.2 million California Hispanics, who total 40% of California's population. 2004 studies estimated that between 300,000 and 500,000 have ancestry descended from the Spanish and Mexican eras of California.
