It was founded at Howard University in Washington, D.C., on January 9, 1914, by three young African-American male students with nine other Howard students as charter members.

Brown, wanted to organize a Greek letter fraternity that would exemplify the ideals of Brotherhood, Scholarship and Service while taking an inclusive perspective to serve 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, youth mentoring clubs, a federal credit union, chapters in Africa and a collegiate chapter outside of the United States.
