 Phi Kappa Psi ( " Phi Psi " ) traces its heritage at Dartmouth College to the Beta Psi local fraternity , founded in 1895 . Beta Psi became the New Hampshire Alpha chapter of Phi Kappa Psi in 1896 . The Dartmouth chapter dissociated from the national in 1967 as a result of the national 's reaction to the chapter 's pledging of a black pledge , adopting the new name Phi Sigma Psi . Phi Sigma Psi was one of the six fraternities that adopted a formal coeducational membership policy in 1972 . In the late 1980s , the membership began referring to the organization as " Phi Psi / Panarchy " . The fraternity changed its name to The Panarchy in 1991 . In 1993 , the college began a program for " undergraduate societies " as open @-@ membership alternatives to the Greek system . In September 1993 , the members of Panarchy voted to disaffiliate from the Greek system and became the first of two Undergraduate Societies .
