Oakland’s territory covers what was once a mosaic of coastal terrace prairie, oak woodland, and north coastal scrub. Its land served as a hunting ground for several Native American tribes before it was explored by Spanish settlers in the late 18th century. During the Rancho and Mission periods, Oakland was primarily inhabited by Ohlone Native Americans and served as a waypoint for American explorers travelling to the region. The city began to rapidly grow after the completion of the Transcontinental Railroad in 1869 and was incorporated in 1872.
