List of Governors of California before admission
This is a list of Governors of California before admission as the 31st U.S. state in 1850. From 1769 to 1822, the area was a province of New Spain. From Mexico's independence in 1822 until 1836, it was a federal territory of the United Mexican States (UEM). From 1836 to 1846, Alta and Baja California were reunited as a "department" of a more centralized UEM. From 1846 to 1850, it was a nominally independent territory in cooperation with the US military. California was admitted as a state on September 9, 1850.
Just prior to the Mexican–American War in 1846, US explorer Capt. John C. Fremont on the frontier sent his companion William B. Ide over to Sonoma, where he helped foment the Bear Flag Revolt, capturing Californian citizens and declaring a short-lived independent California republic.
Ide made many public declarations about himself as conquering "commander" and "President of California," but such bluster had no political substance. The U.S. flag was raised at Sonoma a month later, by Fremont. After the war, Californians continued to elect their own local civil officials under U.S. military governorship.
For governors of the state after admission in 1850, see List of Governors of California.
