When California became a state in 1850, what is now Orange County was part of Los Angeles County. The Gold Rush of 1849 brought tens of thousands of new settlers to the area, providing ranchers with a new market for their livestock. Archaeological evidence suggests that the area was inhabited around 9,500 years ago. At the time of European contact, the northern part of Orange County was mainly inhabited by the Tongva, a part of Tovaangar, while the southern area was mainly inhabited by the Acjachemen.
Both groups lived in villages throughout the area. Large villages were sometimes multiethnic and multilingual, such as Genga, located in what is now Newport Beach. The village was shared by the Tongva and the Acjachemen. The town of Puhú was located in what is now Black Star Canyon and was shared by several groups, including the Tongva, the Acjachemen, the Serrano, and the Payómkawichum.
Other crops such as citrus, avocado, and oil extraction were also important to the initial economy. Orange County benefited from the completion on July 4, 1904, of the Pacific Electric Railway, a streetcar connecting Los Angeles to Santa Ana and Newport Beach. This link turned Orange County into an accessible weekend retreat for celebrities in early Hollywood. It was so important that Pacific City changed its name to Huntington Beach in honor of Henry E.
Huntington, president of Pacific Electric and nephew of Collis Huntington. Transportation improved even more with the completion of the State Highway and U. S. Route 101 (now mostly interstate) in the 1920s.
