1848 – Gold is discovered at Sutter’s Mill. Massive numbers of fortune seekers from around the world begin to make their way to San Francisco to seek their fortunes. Among these new arrivals are large groups of merchant-class Italians from northern Italy. They arrive a full generation before the mass migration of the “…poor huddled masses yearning to breathe free” that came to America following the unification of Italy.
1858 – Thousands of Italian immigrants find themselves without the riches they had anticipated. Many are destitute and in need of assistance. To provide relief for these unfortunates, Nicola Larco, the wealthiest member of the Italian Colony of San Francisco, becomes founding president of La Società Italiana di Mutua Beneficenza, the first and eventually largest mutual benefit society in San Francisco. Today, it is the oldest, continuously-existing Italian organization in the United States.
1868 – After retiring from La Società Italiana di Mutua Beneficenza, community leader Nicola Larco establishes San Francisco's First Columbus Day Celebration, marking the first time in San Francisco and in America that Italian-Americans gather to hold a parade to honor their own accomplishments, as well as to remember the first European to cross the Atlantic Ocean, their countryman Christopher Columbus.

Roaring 20's – The Parade grows to include marching units, bands, decorated automobiles and floats. The celebration lasts over three hours with thousands attending the festivities.

Depression Era – The sponsorship of the Parade shifts from St. Peter and Paul's Church to the Federation of Italian Societies, an organization representing civic, social and fraternal Italian-American organizations.
