Archaeological evidence suggests the San Francisco Bay Area has been inhabited as early as 2700 BC. People of the Ohlone language group occupied Northern California from at least the 6th century. [ verification needed ] Though their territory had been claimed by Spain since the early 16th century, they would have relatively little contact with Europeans until 1769, when, as part of an effort to colonize Alta California, an exploration party led by Don Gaspar de Portolá learned of the existence of San Francisco Bay. Seven years later, in 1776, an expedition led by Juan Bautista de Anza selected the site for the Presidio of San Francisco, which José Joaquín Moraga would soon establish. Later the same year, the Franciscan missionary Francisco Palóu founded the Mission San Francisco de Asís (Mission Dolores).
