Catholicism has greatly influenced the character of San Francisco, beginning with its origins in California in the mission system, which brought Franciscan friars, Spanish soldiers, and new settlers to these shores. Catholics have been witness to history-making events that have included the 1848 Gold Rush, the 1906 earthquake and fire, and the 1918 influenza pandemic. Parishes, schools, hospitals, and charities took shape after the archdiocese's establishment in 1853. The guidance of archbishops, dedication of religious orders, and support of the lay community has made the city named for St. Francis of Assisi into a uniquely Catholic place. The leadership of Catholics in the larger community continues today, enriched by new cultures and traditions.
