Zeta Delta Xi (ΖΔΞ or Zete) is a local, co-educational fraternity at Brown University in Providence, Rhode Island.
For the next one hundred thirty years, the Epsilon chapter of Zeta Psi remained a fixture of life at Brown University.
In 1916 when "at Brown, the new quadrangle buildings arrangement threatened to abolish fraternities,"[2] Zeta Psi moved into a house at 48 College Street.
In 1986, they elected a female president and arranged to have her represent the chapter at the Zeta Psi national convention,"leaving no question about the full and legitimate membership of women".
On December 10, 1986, the Epsilon chapter decided that it could not justify membership in a national fraternity that did not recognize all of its members, and voted unanimously to withdraw from Zeta Psi.
Many of the alums make regular pilgrimages back to Zete in January, to celebrate the anniversary of their founding, and in May, to watch younger members graduate.
