about north of San Jose in what is now Fremont. The Los Angeles Pobladores ("villagers") is the name given to the 44 original Sonorans—22 adults and 22 children—who settled the Pueblo of Los Angeles in 1781. The pobladores were agricultural families from Sonora, Mexico. They were the last settlers to use the Anza trail as the Quechans (Yumas) closed the trail for the next 40 years shortly after they had passed over it. Almost none of the settlers was españoles (Spanish); the rest had casta (caste) designations such as mestizo, indio, and negro. Some classifications were changed in the California Census of 1790, as often happened in colonial Spanish America. The settlers and escort soldiers who founded the towns of San José de Guadalupe, Yerba Buena (San Francisco), Monterey, San Diego and La Reina de Los Ángeles were primarily mestizo and of mixed Negro and Native American ancestry from the province of Sonora y Sinaloa in Mexico. Recruiters in Mexico of the Fernando Rivera y Moncada expedition and other expeditions later, who were charged with founding an agricultural community in Alta California, had a difficult time persuading people to emigrate to such an isolated outpost with no agriculture, no towns, no stores or developments of almost any kind. The majority of settlers were recruited from the northwestern parts of Mexico. The only tentative link with Mexico was via ship after the Quechans (Yumas) closed the Colorado River's Yuma Crossing in 1781. For the next 40 years, an average of only 2.5 ships per year visited California with 13 years showing no recorded ships arriving. In Californio society, casta (caste) designations carried more weight than they did in older communities of central Mexico. One similar concept was the gente de razón, a term literally meaning "people of reason". It designated peoples who were culturally Hispanic (that is, they were not living in traditional Native American communities) and had adopted Christianity. This served to distinguish the Mexican Indio settlers and converted Californian Indios from the barbaro (barbarian) Californian Native Americans, who had not converted or become part of the Hispanic towns. California's Governor Pío Pico was criticized for his alleged descent from mestizo and mulato (mulatto) settlers. Later years of Mexican rule In the 1830s, the newly formed Mexican government was experiencing difficulties, having gone through several revolts, wars, and internal conflicts and a seemingly never-ending string of Mexican Presidents.
