The County of Orange was established in 1889 by founders William Spurgeon and James McFadden. The City of Santa Ana became the county seat the same year. Prior to its formation, the Orange County lands were part of Los Angeles County.
Other surrounding land grants in Orange County were granted and recorded after 1821, that is, after the war of Mexican Independence and by the Mexican government. Some modern day cities in Orange County retain the names of the Mexican land grants as agreed upon in the Treaty of Guadalupe Hidalgo.
