Phi Beta Sigma Fraternity, Inc. (Sigma) was founded on the campus of Howard University in Washington, D.C., on January 9, 1914, by three college students, A. Langston Taylor, Lenard F. Morse, and Charles I. Brown on the principles of Brotherhood, Scholarship, and Service. The founders showcased that idea with the fraternity's motto, "Culture for Service and Service to Humanity."
The founders wanted the organization to be "a part of" rather than "apart from" the community. They also wanted to create an inclusive organization that did not discriminate by racial background, family background, or social status.
The fraternity grew quickly across the nation with chapters from Maryland to Texas by 1920. Also by that date, Phi Beta Sigma members Charles R. Taylor and A. Langston Taylor helped to establish the first "sister" sorority to a black fraternity, Zeta Phi Beta Sorority at the Howard University Campus. Sigma and Zeta are the only constitutionally bound sister-brother organization among black Greek-letter groups. From its founding, the fraternity believed it should be a vehicle for delivering services to the African American community.
The Lambda Xi chapter was chartered May 6th, 1980 on the campus of Arizona State University. These young men wished to strengthen and serve proactively the brotherhood , as a supportive resource that positively impacts the Fraternity's growth and financial solvency.
