Zeta Phi Beta Sorority, Inc. was founded January 16, 1920, at Howard University, Washington, D.C.  The Klan was very active during this period and the Harlem Renaissance was acknowledged as the first important movement of Black artists and writers in the U.S.  This same year the Volstead Act became effective heralding the start of Prohibition and Tennessee delivered the crucial 36th ratification for the final adoption of the 19th amendment giving women the right to vote.  The worst and longest economic recession to hit the U.S. would define the end of the decade-The Great Depression.

​

​Since its inception, Zeta has continued its steady climb into the national spotlight with programs designed to demonstrate concern for the human condition both nationally and internationally.  The organization has been innovative in that it has chronicled a number of firsts.  It was the first National Pan-Hellenic Council organization to centralize its operations in a national headquarters, first to charter a chapter in Africa, first to form auxiliary groups, and first to be constitutionally bound to a fraternity, Phi Beta Sigma Fraternity, Inc.   The sorority takes pride in its continued participation in transforming communities through volunteer services from members and its auxiliaries.  Zeta Phi Beta has chartered hundreds of chapters worldwide and has a membership of 100,000+.
