On August 5, 1775, the Spanish ship San Carlos, commanded by Juan Manuel de Ayala, entered what would soon be called San Francisco Bay. Unnoticed by such early naval explorers as Sir Francis Drake and Sebastián Vizcaíno, the bay had been sighted by land during a Spanish scouting expedition six years earlier.
Spanish authorities, intent on offering proof of Spain’s claim to the area, promptly sent nearly two hundred settlers to populate the region. In 1776 both a presidio, or garrison, and a Catholic mission were established. Mission San Francisco de Asís (Mission Dolores) was started by Franciscans, who named both the bay and the mission after the founder of their religious order, St. Francis of Assisi.
As early as 1835, the United States sought to buy San Francisco Bay from Mexico (independent of Spain since 1821), the same year that a small town called Yerba Buena was founded. It was not until after the end of the Mexican War that California was ceded to the United States as a provision of the 1848 Treaty of Guadalupe Hidalgo, signed within days of the discovery of gold along the American River. By then, Yerba Buena had claimed its new name, San Francisco—and the Gold Rush was on.
I soon shall be in Frisco,
And then I’ll look around;
And when I see the gold lumps there,
I’ll pick them off the ground. O California,
That’s the land for me:
I’m bound for San Francisco,
With my washboard on my knee.
