The fraternity's founders, Abram Langston Taylor, Leonard Frances Morse, and Charles Ignatius Brown, wanted to organize a Greek letter fraternity that would exemplify the ideals of Brotherhood, Scholarship and Service while taking an inclusive perspective to serving the community as opposed to having an exclusive purpose . The fraternity exceeded the prevailing models of Black Greek - Letter fraternal organizations by being the first to establish alumni chapters, to establish youth mentoring clubs, to establish a federal credit union, to establish chapters in Africa, and establish a collegiate chapter outside of the United States, and is the only fraternity to hold a constitutional bond with a predominantly African - American sorority, Zeta Phi Beta (ΖΦΒ), which was founded on January 16, 1920, at Howard University in Washington, D.C., through the efforts of members of Phi Beta Sigma Fraternity . </P>
