- History of San Francisco
Around 10,000 years ago, before the Pacific waters had breached the span now covered by the Golden Gate Bridge, the history of the Ohlone people native to San Francisco had already begun. Complex chiefdoms arose and fell, the scarce remnants of which are the infamous "shellmounds," large heaps of piled shells and other artifacts on the Bay Area's shores. San Francisco history continued untouched by Europeans until 1579 when Sir Francis Drake, the decorated English looter of Spanish galleons sailed past the entrance to the San Francisco Bay.
San Francisco history remained devoid of Europeans until 1775, when the Spanish, long having a stronghold in Southern California, ventured north on a "Sacred Expedition" led by Gaspar de Portola. In 1776, the Spanish founded the Presidio Army Base and the Catholic Church commenced capturing and enslaving the San Francisco Ohlone population.
