Founded in 1904, the nation’s oldest Black Greek-letter fraternity has shaped American civic, intellectual, and political life through deliberate leadership and global influence
Founded on May 15, 1904, Sigma Pi Phi Fraternity, known as The Boulé, stands as the oldest continuously existing Black Greek-letter fraternity in the United States—and among the most influential yet deliberately private institutions in American history. Created by and for eminent Black professional men at a time when racial barriers sharply limited opportunity, the fraternity has spent more than a century shaping leadership across law, medicine, education, politics, science, and the arts.
The fraternity’s name draws from ancient Greece, where a boulé referred to a council of chiefs. That concept—measured counsel, collective responsibility, and strategic leadership—defined the organization from its inception. Its six founders, all medical and health professionals or students in Philadelphia, envisioned a fraternity that would strengthen professional bonds while uplifting underserved Black communities through service, advocacy, and institutional excellence.
From the outset, Sigma Pi Phi emphasized quality over quantity. Membership was never intended to be broad or indiscriminate. Instead, it has remained selective, extended to accomplished men with proven records of professional achievement and demonstrated commitment to the advancement of Black communities. That philosophy has guided the fraternity’s growth from six founding members in Philadelphia to more than 5,000 active members affiliated with 139 local boulés across the United States, the Bahamas, and the United Kingdom.
