Tau Kappa Epsilon (
ΤΚΕ or
Teke, pronounced T-K-E or Tēk) is an international all-male secret and social
college fraternity founded on January 10, 1899, at
Illinois Wesleyan University. The organization has chapters in the United States, Canada, and an affiliation with a German fraternity system known as the
Corps of the
Weinheimer Senioren-Convent (WSC). As of Fall 2015 there were 251 active TKE chapters and colonies throughout the United States and Canada. In 1928, TKE became one of the first fraternities to abolish "
hell week", instead replacing it with a secret initiation period.
