In 1846, the United States declared war on Mexico. That June, Americans under John C. Fremont staged their own rebellion in Sonoma, California. Calfironios, or Mexican Californians, soon fought back. By fall, the entire southland, from San Diego to San Luis Obispo, was back under Mexican control. But the war effort was too difficult to sustain without reinforcements from Mexico. When American troops occupied Mexico City in 1847, the nation conceded defeat. |
