The modern-day cities of San Jose, Los Angeles and San Diego all began as Spanish pueblos in the 18th century. Pueblos were agricultural towns that were essentially established to support a presidio (soldier's home) or military establishment.
Pueblos were established by the Spanish as part of their colonization of North America and were designed to bring in civilian communities. San Diego was established as a presidio in 1769, and San Jose was established as a pueblo in 1777. El Pueblo de la Reina de los Angeles, or the Queen of the Angels' Town, was the original name of Los Angeles, which was established in 1781. The Spanish eventually established eight pueblos; all but one still exist as part of the United States.
