Among the most densely populated cities in the country, San Francisco is part of the San Francisco Bay Area metropolitan area, which is home to more than 7.2 million people. The city is located at the tip of the San Francisco Peninsula, with the Pacific Ocean to the west, San Francisco Bay to the east, and the Golden Gate to the north. In 1776, the Spanish settled the tip of the peninsula, establishing a fort at the Golden Gate and a mission named for Francis of Assisi. The California Gold Rush in 1848 propelled the city into a period of rapid growth, transforming it into the largest city on the West Coast at the time. After being devastated by the 1906 earthquake and fire, San Francisco was quickly rebuilt, hosting the Panama-Pacific International Exposition nine years later. During World War II, San Francisco was the send-off point for many soldiers to the Pacific Theater. After the war, the confluence of returning servicemen, massive immigration, liberalizing attitudes, and other factors gave rise to the Summer of Love and the gay rights movement, cementing San Francisco as a liberal bastion in the United States.location_typeCitypopulation_info_as_of2007government_typeConsolidated city-countylatitude_nsNfounding_date1776-06-29 00:00:00.0founding_date1850-04-15 00:00:00.0source_urlhttp://en.wikipedia.org/wiki/San_Francisco,_Californialongitude_ewWnameRepresentationnameCity and County of San Franciscolatitude_minute46mottoOro en Paz, Fierro en Guerrawikipedia_inbound_page_count7781longitude_minute25population_total764976also_known_asThe City by the Bay, San Fran, Frisco, The City That Knows How (archaic), Baghdad by the Baywebsitewww.sfgov.orglongitude_degree122LOCATION
