The earliest recorded inhabitants were the Huchiun tribe, who were heavily concentrated around Lake Merritt and Temescal Creek in Oakland. Oakland was claimed for the Spanish king by explorers from New Spain in 1772 (as was the rest of California), and in the early 19th century, the area which later became Oakland, was granted to Luis Maria Peralta by the Spanish royal government. The area of the ranch that is today occupied by the downtown was called 'encinal' by the Peraltas, a Spanish word which means "oakland", the origin of the later city's name. Peralta divided his land among his four sons in 1842, and most of Oakland fell within the shares given to Antonio Maria and Vicente. They would open the land to settlement by American settlers, loggers, European whalers, and fur-traders. Full-scale settlement and development occurred in California after 1848, and the California state legislature incorporated the town of Oakland on May 4, 1852.
