Barbary Coast

With ships, merchandise and equipment, and thousands of sea-route
argonauts pouring into California through the Golden Gate, San
Francisco instantly became the hub of the gold rush. No city grew
bigger or faster, or with more hustle and bustle. Its population
in January 1848 was 800; by 1853 it had mushroomed to over 50,000,
with tens of thousands more passing through to and from the mines
each year. San Francisco quickly became the most culturally and
ethnically diverse place in the world. While the gold rush laid
the foundation of the city, it took the wealth of the Comstock
silver bonanza in Nevada to really build and refine it.
The Comstock created fortunes for men like William Ralston, the
builder of the Palace Hotel. Ralston and other newly-wealthy San
Franciscans sought to create their own vision of San Francisco
as an "Imperial City," a sophisticated, cultured city to rival
New York, London and Paris.
