The College introduced undergraduate societies to campus in 1993, as a residential and social alternative to Greek organizations. Similar to the Greek houses in many respects, undergraduate societies were required to have open, coeducational membership policies. Panarchy, a coeducational fraternity with a 97-year history at Dartmouth, voted to change its status to an undergraduate society and was joined the following year by a newly formed society, called Amarna. Phi Tau chose to remain a Greek house. In 1999, the College administration announced a "Residential and Social Life Initiative" to improve campus life. Speculation that all Greek houses at Dartmouth College might be forced to open admissions to anyone who wanted to join drew attention to Phi Tau's status as an already coeducational institution, but one that still held to Greek traditions. Then house president Virginia DeJesus-Rueff, class of 2000, defended Phi Tau's policy of self-selection.
