Columbus Under Attack - Defend Our Heritage


We are a national organization of men and women who represent the estimated 17 million Americans of Italian heritage, dedicated to promoting our culture, our traditions, our language, the legacy of our ancestors, and our contributions to the U.S. and the world. We are sons and daughters, grandmothers and grandfathers. We are corporate executives and we are union members…young students and retirees…teachers and attorneys…doctors and firefighters…bakers and Wall Street brokers…and everything in between. We are philanthropists and we are model global citizens with purpose beyond ourselves. And we are proud and patriotic Americans of Italian heritage. We exemplify the very best of what it is to be Italian American.

  • The Order Sons and Daughters of Italy in America® (OSDIA) is the largest and oldest national organization for men and women of Italian heritage in the United States.
  • Founded in 1905 as a mutual aid society for the early Italian immigrants, today OSDIA has thousands of family members located in all fifty states and the District of Columbia, making it the leading service and advocacy organization for the nation’s estimated 26 million people of Italian descent.
  • Its missions include encouraging the study of Italian language and culture in American schools and universities; preserving Italian American traditions, culture, history and heritage; and promoting closer cultural relations between the United States and Italy.

  • OSDIA is for people of any gender, age, religion, race, creed, orientation and profession. You don’t even have to be Italian to join! Whether you are of Italian heritage or simply have a love for things Italian, OSDIA welcomes you as a member.
  • The Sons of Italy Foundation® (SIF) is a private, philanthropic institution established by OSDIA in 1959. To date, the SIF has given more than $164 million to scholarships, medical research, cultural preservation, disaster relief, and other causes.
