The document summarizes the founding and establishment of the 21 Spanish missions in California between 1769-1771. Junipero Serra established the first mission in San Diego in 1769 after being asked by Jose de Galvez to lead the expedition. Later missions were established as far north as Sonoma by Serra and other priests to convert Native Americans to Catholicism, though many Native Americans revolted against the conditions at the missions. Life at the missions involved farming, religious services, and work.
