 Zeta Psi ( " Zete " ) at Dartmouth College was founded in 1853 as the Psi Epsilon chapter of the national fraternity , and was the fifth fraternity founded at the college . The fraternity became inactive in 1863 , but was revived from 1871 through 1873 after which it again became inactive . The current Psi Epsilon Chapter of Zeta Psi at Dartmouth was established in 1920 . In 2001 , the Dartmouth chapter was derecognized by the college because " the fraternity harassed specific fellow students and violated ethical standards that Dartmouth student organizations agree to uphold , by periodically creating and circulating among Zeta Psi members ' newsletters ' that purported to describe situations , some of them of a sexual nature , of various members of the fraternity and other students . " Zeta Psi , meanwhile , countered that " nothing could be further from the truth ... Dartmouth College lacks jurisdiction to punish Psi Epsilon of Zeta Psi 's for alleged violations of its own rules or regulations , " . From 2001 to 2006 , Zeta Psi continued to operate as an independent fraternity , not officially recognized by Dartmouth College . In January 2007 , Dartmouth College announced an agreement that would allow Zeta Psi to reorganize on campus as early as 2009 . Part of the agreement dictated that the organization " go dark " , with no activities or recruiting , for a period of two years . During these two years , alumni raised millions of dollars and the physical plant was entirely gutted and renovated , with a three @-@ story addition being constructed on the west @-@ side of the house . Also , the basement was enlarged . On October 12 , 2009 , the Psi Epsilon Association of Zeta Psi Fraternity ( Dartmouth Zete 's alumni association ) announced that 35 undergraduates had joined the newly re @-@ recognized fraternity . As of January 2011 , after only little more than a year , Zete has around 60 brothers and counting .
