San Francisco: History
=== Indigenous history ===
The earliest archeological evidence of human habitation in the area dates to 3000 BCE. The Ohlone name for San Francisco was Ahwaste, meaning "place at the bay". The Yelamu group of the Ramaytush people lived in a few small villages when an overland Spanish exploration party arrived on November 2, 1769, the first documented European visit to San Francisco Bay. The arrival of Spanish colonists, and the establishment of the Mission system, marked the beginning of the assimilation of the Ramaytush people and the decline of their language and culture.
The Spanish Empire claimed San Francisco as part of Las Californias, a province of the Viceroyalty of New Spain. The Spanish first arrived in what is now San Francisco on November 2, 1769, when the Portolá expedition, led by Don Gaspar de Portolá and Juan Crespí, arrived at San Francisco Bay. Having noted the strategic benefits of the area due to its large natural harbor, the Spanish dispatched Pedro Fages in 1770 to find a more direct route to the San Francisco Peninsula from Monterey, which would become part of the El Camino Real route.
In 1774, Juan Bautista de Anza arrived in the area to select sites for a mission and presidio. The first European maritime presence in San Francisco Bay occurred on August 5, 1775, when the Spanish ship San Carlos, commanded by Juan Manuel de Ayala, became the first ship to anchor in the bay.
Soon after, on March 28, 1776, Anza established the Presidio of San Francisco and on October 9, Mission San Francisco de Asís, also known as Mission Dolores, was founded by Padre Francisco Palóu. In 1794, the Presidio established the Castillo de San Joaquín, a fortification on the southern side of the Golden Gate, which later came to be known as Fort Point.
In 1804, the province of Alta California was created, which included San Francisco. At its peak in 1810–1820, the average population at the Mission Dolores settlement was about 1,100 people.
In 1821, Spain ceded the Californias to Mexico. The extensive California mission system gradually lost its influence during the period of Mexican rule, although it was not until 1833 that the missions would be secularized. Agricultural land became largely privatized as ranchos, as was occurring in other parts of California. Coastal trade increased, including a half-dozen barques from various Atlantic ports which regularly sailed in California waters.
With the enactment of the Mexican Secularization Act of 1833, the missions were required to divest themselves of their extensive landholdings and emancipate the indigenous people under their control. As part of the process of secularization, Governor José Figueroa opened up San Francisco to civilian settlement. Prior to secularization, the only settlements in San Francisco had been the military settlement at the Presidio and the religious settlement at Mission Dolores. In 1835, the Presidio garrison, commanded by Mariano Vallejo, relocated to the Presidio of Sonoma, which was regarded as needing a greater military presence due to the proximity of the Russian settlement at Fort Ross. Only a small detachment remained at the Presidio of San Francisco. Mission Dolores sold most of its property in 1836, retaining only the church and related structures. …
