Ranchos of California - American Era

American Era

The United States (US) declared war against Mexico on May 13, 1846. Action in California began with the Bear Flag Revolt on June 15, 1846. On July 7, 1846, US forces took possession of Monterey, the capital of California, and terminated the authority and jurisdiction of Mexican officials that day. Armed resistance ended in California with the Treaty of Cahuenga signed on January 13, 1847. The Treaty of Guadalupe Hidalgo, ending the war, was signed February 2, 1848 and California became a Territory of the United States. Between 1847–1849, California was run by the U.S. military. A constitutional convention met in Monterey in September 1849, and set up a state government. It operated for 10 months before California was admitted to the Union as the 31st State by Congress, as part of the Compromise of 1850, enacted on September 9, 1850.
