Delta Chi (ΔΧ) (del-ta kai) or D-Chi is an international Greek letter college social fraternity formed on October 13, 1890, at Cornell University, initially as a professional fraternity for law students. In 1922, Delta Chi became a general membership social fraternity, eliminating the requirement for men to be studying law, and opening membership to all areas of study. In 1929 Delta Chi became the first international fraternity to outlaw hazing. Delta Chi is a charter member of the North-American Interfraternity Conference (NIC). The Fraternity is headquartered at 314 Church Street in Iowa City, Iowa. Delta Chi, as of Fall 2009, has reached the milestone of having over 100,000 initiates.
