Secret societies have been a part of
University of Virginia student life since the first class of students in 1825. While the number of societies peaked during the 75-year period between 1875 and 1950, there are still six societies (
Seven Society,
Z Society,
IMP Society,
Eli Banana, T.I.L.K.A., The Thirteen Society) active that are over 100 years old, and several newer societies (the Purple Shadows, the A.N.G.E.L.S. Society,
The 21 Society, P.U.M.P.K.I.N., the Sons and Daughters of Liberty, and The Thursdays Society). The earliest societies, Eli and Tilka, functioned as social clubs; the Zs, IMPs, and Sevens have built a record of philanthropy and contribution to the University; and some of the later societies have focused on recognition or disapprobation of positive and negative contributions to the University.
