Established in 1905 as a mutual aid society for the early Italian immigrants, today OSDIA has more than 600,000 members and supporters and a network of more than 700 chapters coast to coast, making it the leading service and advocacy organization for the nation's estimated 26 million people of Italian descent. 

The organization's 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. 

The Sons & Daughters of Italy Foundation, established by OSDIA, is a private, philanthropic institution that has contributed millions of dollars for scholarships, medical research, cultural preservation and disaster relief. 

The Commission for Social Justice is the anti-defamation arm of OSDIA 

The History of OSDIA

Nineteenth century America saw the rapid growth of mutual aid societies throughout the land. In the tradition of volunteering and cooperation, thousands of community organizations were formed. The mutual aid society was a source of great comfort for the immigrants because it provided a familiar setting in which a native language was spoken and old world customs practiced.

The Italian American societies were characterized by the provincial and village ties that were present in Italy. While many of the Italian immigrants had belonged to such organizations in their native land, there the focus was on providing sick and death benefits. However, in America these mutual aid societies had a greater focus on social interaction and were indispensable in assisting rural immigrants in adjusting to urban and industrial life. They were found in virtually every Italian community in America. Eventually, feelings of Italiania began to emerge as Italian American needs and interests transcended the traditional regional and paesi bonds. The development of this ethnic identity by Italians led to the formation of L'Ordine figli d'Italia in America, Order Sons & Daughters of Italy in America.

Dr. Vincenzo Sellaro (1868-1932) developed the idea of uniting the Italians into one great organization which would enable them to become the authors of their own destinies. Dr. Sellaro was born in Polizza Generosa, Palermo, Sicily and came to the United States in 1897. Recognizing the need to unite the multitude of Italian mutual aid societies into a single federation, Dr. Sellaro and five other Italian immigrants founded The Supreme Lodge, Order Sons & Daughters of Italy in America on June 22, 1905.

The Supreme Lodge

The Order Sons & Daughters of Italy in America (OSDIA) is an organizational structure of national, state, and local lodges. OSDIA is a lodge system consisting of the Supreme Lodge, the Grand Lodge, and the Local Lodge with a volunteer form of work and a representative form of government. The Supreme Lodge office is located in Washington, D.C. and is governed by a Constitution and General Laws applicable to the Grand Lodges and all members of OSDIA.

The officers are elected for a term of two years at the biennial national convention held in the odd numerical years. OSDIA is the largest established representing Americans of Italian heritage, with 500,000 family members and 750 local chapters in 35 states. OSDIA, through its two subsidiary entities, the Sons & Daughters of Italy Foundation, and the Commission for Social Justice, works to preserve and promote the cultural heritage of Americans of Italian decent. The Supreme Lodge is a tax-exempt entity under Section 501(c)(8) of the Internal Revenue Code, a fraternal organization.

The principles of OSDIA are:

Liberty: We want freedom of assembly, of speech, of opportunity – and above all economic freedom. We want individual freedom of thought, of conscience, and of religion. Liberty is the most essential and precious prerogative.

Equality: We believe that all people were created equal without distinction as to race, color, creed, caste or class.

Fraternity: We affectionately offer a hand to all and keep alive the traditions of our ancestors.

The emblem of the Order is a Golden Lion in a field of white signifying strength.

The color of the Order is purple.


OSDIA is organized within three levels:

The National Lodge sets goals and coordinates activities in 20 state chapters and 750 community based chapters.

The State Lodge informs all lodges of activities and goals of the National and State Lodge. Each state has its own State Lodge. The Local Lodges are based in various communities and carry through the various programs of National and State OSDIA.

They work diligently to also support their own communities.

The flower of the Order is purple Aster.
