Zeta Beta Tau expanded rapidly. By 1909, it had established 13 chapters in the Northeastern United States and a 14th at Tulane University in New Orleans. In 1913, it established its first Canadian chapter at McGill University in Montreal and, in the same year, Zeta Beta Tau was first represented at the National Interfraternity Conference. Five years later, it founded its first West Coast chapter at the University of Southern California in Los Angeles. At the 1954 National Convention, the delegates amended Zeta Beta Tau's constitution, ritual and internal procedures both in theory and in practice to eliminate sectarianism as a qualification for membership.
