Overview
The California Republic was the very short-lived state proclaimed by American settlers in Mexican Alta California during the Bear Flag Revolt of June 1846. As tensions between the U.S. and Mexico escalated toward war, a group of American settlers and adventurers near Sonoma, encouraged by the presence of U.S. Army explorer John C. Frémont, seized the town and detained the Mexican official Mariano Vallejo. On 14 June 1846, they proclaimed an independent "California Republic" and raised a hastily made flag depicting a grizzly bear and a star — the origin of the modern California state flag and the phrase "Bear Flag Republic."
History
The republic had no real government, constitution, or defined leadership beyond a handful of rebels (William B. Ide issued a proclamation), and it controlled only the area around Sonoma. Its existence was almost immediately overtaken by events: unbeknownst to the rebels, the Mexican–American War had already begun.
Decline and legacy
Within about three weeks, U.S. naval forces under Commodore John D. Sloat raised the American flag over Monterey (7 July 1846) and claimed California for the United States. The Bear Flag was lowered, and the "republic" — which had lasted roughly 25 days — was absorbed into the U.S. military conquest of California. Mexico formally ceded California in the Treaty of Guadalupe Hidalgo (1848), and the discovery of gold days earlier (January 1848) triggered the Gold Rush; California became a U.S. state in 1850. The Bear Flag Republic's chief legacy is symbolic — the enduring state flag and California's "Bear Flag" identity.
