 National social changes also affected Greek societies at Dartmouth in the 1960s and 1970s . Many began to question the value of belonging to a national fraternal organization . The Dartmouth chapters of Chi Alpha Rho , Chi Phi , Delta Upsilon , Phi Gamma Delta , Phi Kappa Psi , and Sigma Phi Epsilon all disaffiliated from their national fraternities in the 1960s . As political activism increased , fraternities were increasingly seen as anachronistic , and in 1967 , the faculty voted 67 @-@ 16 to adopt a proposal to abolish fraternities at Dartmouth . The proposal was rejected by the Board of Trustees .
