Andrés Pico (November 18, 1810 – February 14, 1876) was a Californio who became a successful rancher, fought in the contested Battle of San Pascual during the Mexican–American War, and negotiated promises of post-war protections for Californios in the 1847 Treaty of Cahuenga.
After California became one of the United States, Pico was elected to the state Assembly and Senate.
He was appointed as the commanding brigadier general of the state militia during the U.S.
