The term Triad is used to designate certain historic groupings of seminal college fraternities in North America.
[2][3] Delta Zeta sorority was founded at Miami University in 1902, and Phi Kappa Tau fraternity in 1906.
[7] This tradition has waned in recent years and some schools have transformed the celebration into new events, such as the University of Kansas' Miami Triad Concert.
[14] Two national sororities were founded at Wesleyan College in Macon, Georgia, Alpha Delta Pi (1851) and Phi Mu (1852).
General (social) sororities were banned on that campus in 1914, but this occurred long after the two organizations, called the "Macon Magnolias," had expanded nationally.
