List of governors of California before 1850

Gaspar de Portolá, 1st Governor of the Californias.

Don Pío Pico, last Governor of Alta California.

Below is a list of the governors of early California (1769–1850), before its admission as the 31st U.S. state. First explored by Gaspar de Portolá, with colonies established at San Diego and Monterey, California was a remote, sparsely-settled Spanish province of New Spain. In 1822, following Mexican independence, California became part of Mexico.

In 1836, a coup led by Californios Juan Bautista Alvarado and José Castro eventually resulted in Alvarado becoming governor.^[1] That conflict ended in 1838, when the central government of Mexico recognized Alvarado as California Governor. The territorial diputación (legislature) approved the appointment.

Another disputed governorship occurred in 1844, settled when another Californio, Pio Pico, became the last Governor of Mexican California. In 1846, the "Bear Flag Revolt" in Sonoma declared California an independent republic—the "Bear Flag Republic". No government was formed, however, and the revolt did not have time to spread very far because California came under U.S. military occupation at the outset of the Mexican–American War less than a month later. California was ceded to the U.S. in 1848, and was admitted as the 31st U.S. state on September 9, 1850. Peter Burnett, the last governor of the post-war military territory, became its first state governor after admission.

Spanish rule (1769–1822)

The Spanish Empire established its rule in the Californias in 1769. During this time, the Californias encompassed a massive territorial expanse, including both Alta California (present day U.S. state of California) and Baja California (present day Mexican states of Baja California and Baja California Sur), which were governed under a military administration led by the Governor of the Californias. In 1804, the Californias were officially divided into two administrations: Alta California, based in Monterey, and Baja California, based in Loreto.

Spanish governors of the Californias (1769–1804)

From 1769 to 1804, the Californias were governed as one administrative unit within the Spanish Empire. Following 1804, Alta California and Baja California each had their own administration.

Mexican rule was interrupted from 1836 to 1838 by the Californio independence movement led by Juan Bautista Alvarado, who was acclaimed President of Alta California. However, Alvarado entered into negotiations with the Mexican government in 1838, which resulted in the disbandment of the Californio independence movement in favor of greater autonomy and the appointment of Alvarado as governor, thus reestablishing Mexican rule in Alta California, which lasted until 1846.

Following the appointments of unpopular governors Gutiérrez and Chico, Juan Bautista Alvarado successfully led a popular uprising of Californios in 1836 which deposed Gutiérrez, proclaimed the independence of Alta California from Mexico, and named Alvarado as its president. Alvarado maintained effective control over California until he entered into negotiations with the Mexican central government in 1837, which resulted in the disbandment of Alta Californian independence in favor of greater autonomy from the Mexican government and recognition of Alvarado as Governor of Alta California.

Mexican governors of California (1837–47)

While Juan Bautista Alvarado maintained effective control as President of Alta California from 1836 to 1837, the Mexican central government appointed noted Californio statesman Carlos Antonio Carrillo as Governor of California^[2] to lead the nationalist offensive against Alvarado. As Carrillo was unsuccessful, Alvarado and the Mexican central government negotiated an end to the civil war in Alta California, resulting in Alvarado's abandonment of independence in favor of greater autonomy and the governorship, thus reestablishing the continuity of Mexican governance over Alta California.
