Community History, Neighborhoods & Cultural Legacy

The 1849 California Gold Rush triggered a westward migration of thousands of Irishmen. In booming San Francisco, the Irish found a young city unburdened by the entrenched puritan aristocracy of New England, allowing them to rapidly rise into banking, municipal politics, and commerce.

Irish immigrants populated the Mission District and South of Market (SoMa). Irish-born pioneers like James C. Flood and James G. Fair (the “Bonanza Kings”) built financial empires from the Comstock Lode, funding the architectural landmarks of San Francisco.
