Phi Beta Sigma is a unique fraternal organization because of our distinct relationship with our constitutionally bonded sister organization, Zeta Phi Beta Sorority, Inc.

While often imitated...the bond between the gentlemen of Phi Beta Sigma Fraternity and the lovely ladies of Zeta Phi Beta Sorority can never be duplicated, we stand to date as the only true sisterhood and brotherhood in greekdom. Zeta Phi Beta, together with Phi Beta Sigma comprise the only officially bound brother and sister greek letter soceties. We both enjoy and foster a mutually supportive relationship.

Zeta Phi Beta Sorority Inc. was founded on the campus of Howard University on January 16, 1920, as the result of encouragement given to the five founders by Charles Taylor and the Langston Taylor, members of Phi Beta Sigma Fraternity, Inc. These Sigma Brothers felt the campus would benefit by the development of such an organization as sisters to the fraternity. Thus Zeta and Sigma became the first official, greek-lettered, sister and brother organization.

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 trail blazed by the founders has been traversed by thousands of women dedicated to the emulation of the objectives and ideals of the Sorority.

In 1948, Zeta became the first Greek-letter organization to charter a chapter in Africa (Sierra Leone in West Africa); to form adult and youth auxiliary groups, the Amicae, Archonettes, Amicettes, and Pearlettes; and, of course, to be constitutionally bound to a brother group, Phi Beta Sigma Fraternity, Incorporated. Since its inception, Zeta Phi Beta has expanded to over 500 collegiate and graduate chapters, located throughout the continental United States, Alaska, and Hawaii. Today, Zeta's influence is felt world wide, from the Caribbean and Germany to Seoul, South Korea.

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.
