The U.S. government appointed the influential Vallejo as Indian agent for Northern California. He also served on the state constitutional convention in 1849. Afterward, Vallejo remained active in state politics, but challenges to his land titles around Sonoma eventually left him impoverished and reduced his ranch from 250,000 acres to a mere 300. He eventually retired from public life, questioning the wisdom of his having welcomed the American acquisition of California in the first place. Vallejo died in 1890, a symbol of the eclipse of Californio wealth, power, and prestige.
