Zeta Phi Beta Sorority was founded January 16, 1920 on the campus of Howard University in Washington, D.C. by five coeds. These women dared to depart from the traditional coalitions for Black women and sought to establish a new organization predicated on the precepts of Scholarship, Service, Sisterhood and Finer Womanhood. 

The Sorority was the, first Greek-letter organization to charter a chapter in Africa (1948); to form adult and youth auxiliary groups, the Amicae, Archonettes, Amicettes, and Pearlettes; and to be constitutionally bound to a brother group, Phi Beta Sigma Fraternity, Incorporated.

Zeta's national and local programs include endowment of its National Educational Foundation; community outreach services; and support of multiple affiliate organizations. Zeta chapters and auxiliary groups have given untotaled hours of voluntary service to educate the public, assist youth, provide scholarships, support organized charities and promote legislation for social and civic change. A nonprofit organization, Zeta Phi Beta is incorporated in Washington, D.C. and in the state of Illinois. The Sorority is supported by the dues and gifts of its members.
