The Bear Flag is the official flag of the U.S. state of California. The precursor of the flag was first flown during the 1846 Bear Flag Revolt and was also known as the Bear Flag. A predecessor, called the Lone Star Flag, was used in an 1836 independence movement; the red star element from that flag appears in the Bear Flag of today.
