Lore & Background
Europeans reached the area in 1539 with Francisco de Ulloa, followed by Hernando de Alarcón and Juan Rodríguez Cabrillo. Jesuit missions were established in the 18th century, and after the Jesuits' expulsion, Franciscans and then Dominicans administered the region. In 1804, the Spanish crown divided California into Alta and Baja California. After Mexican independence, the Mexican-American War resulted in the U.S. gaining Alta California, while Baja California remained Mexican. In 1952, the North Territory became the state of Baja California.
