Growth led the California legislature to divide Los Angeles County and create Orange County as a separate political entity on March 11, 1889. The county is said to have been named for the citrus fruit (its most famous product). In the new county there was already a town by the name of Orange, named for Orange County, Virginia, which took its name from William of Orange, a famous protestant King of Great Britain and Ireland. The fact the county took the same name as one of its towns may have been coincidence. However, it is also possible that the county was named for this city (and thus indirectly for William of Orange, whose family name was itself derived from the French town of Orange named in ancient times in honour of a celtic water deity).
Orange county is the second most densely populated county in the state, second only to San Francisco County. The county's four largest cities, Anaheim, Santa Ana, Irvine, and Huntington Beach each have populations exceeding 200,000. Several of Orange County's cities are on the Pacific coast, including Huntington Beach, Newport Beach, Laguna Beach, and San Clemente.
