Part of the Alpha Delta Phi International, Inc., sharing the heritage, traditions, and history of the Alpha Delta Phi which dates back to 1832. In 1992 the Alpha Delta Phi divided into two separate and self-governing organizations: the Alpha Delta Phi Fraternity with twenty-eight chapters and the Alpha Delta Phi Society with six chapters. The basic difference between the two organizations is that the Society has a "home rule" membership policy that welcomes co-educational chapters, while the Fraternity's constitution limits membership to males.
