By Charles A. Coulombe, OnePeterFive - The arrival of St. Junípero Serra and the Spanish in 1769 changed this picture considerably. With additional meats, vegetables, and grain, the standard of living of the Mission Indians rose considerably. By 1821, twenty missions were founded, in a mostly coastal chain from San Diego to San Rafael, with a 21st being founded under Mexican rule at Sonoma two years later. Two cities were founded – Los Angeles and San Jose – and four presidios or forts at San Diego, Santa Barbara, Monterey, and San Francisco.
