It is a chartered county in the state of California governed by a five member Board of Supervisors. Each of the supervisors is dlected from a specified geographic district and the entire board makes policy, authorizes expenditures and oversees the departments and agencies of the county. A chairman and vice chairman are chosen from among the elected supervisors each year. The county is administered by a municipal manager known as the County Executive who is hired by the Board of Supervisors.

How was Orange County named?

Orange County was not a rare name back in 1880. Six other states also had an Orange County as well as many cities and towns named Orange. Taken from Los Angeles County on 11 March 1889, Orange County was named because of the successful orange industry here. Hundreds of orange groves dotted the county area, making it beautiful and sweet-smelling during the orange blossom season each year.
Here is a page about how the county was named.
Several attempts to form a new county were tried - first to name it the county of Anaheim, then Orange, then Santa Ana County and finally, on the 6th try, the county was formed and named Orange County with the county seat in Santa Ana. The fledgling citrus industry had not really gotten a foothold here, but was just beginning when the county was formed. Those who helped to form and name the county were hoping the name of Orange would lure in newcomers from other areas to partake of the good weather, the good citrus fruit and growing real estate.

The first explorers to come to the Orange County area came in late July in 1769. For more details see any of the history websites shown above.
