Alpha Delta Gamma

Alpha Delta Gamma (ΑΔΓ), commonly known as ADG, is an American Greek-letter Catholic social fraternity and one of 75 members of the North American Interfraternity Conference (NIC). Based on Christian principles and the traditions of the Jesuit Order of the Catholic Church,[1] Alpha Delta Gamma was founded at Loyola University Chicago on October 10, 1924, as a response to the unwillingness of most national fraternities to colonize at Catholic colleges and universities. Since its founding, Alpha Delta Gamma has expanded conservatively to keep a small but strong brotherhood; thus, the fraternity has chartered 33 chapters in its long history.[2] Today, Alpha Delta Gamma operates 14 active chapters at private and public colleges across the United States, stretching from Los Angeles, California, to New York City, New York.[3]

Alpha Delta Gamma was founded at the Lake Shore campus of Loyola University Chicago on October 10, 1924, by four students: Francis Patrick Canary, John Joseph Dwyer, William S. Hallisey and James Collins O'Brien Jr. According to the Alpha Delta Gamma National Web Site, "In effect, they wanted a fraternity founded upon Christian ideals of true manhood, sound learning, and the unity of fraternal brotherhood. These ideals decreed the purpose of Alpha Delta Gamma when it first came into being. And so the foundation was set, Alpha Delta Gamma was on its way to becoming a city walled!"[4]

In 1926, members of the local organization Delta Theta at Saint Louis University in St. Louis, Missouri, contacted the Alpha chapter at Loyola University Chicago, requesting permission to affiliate with the then existing fraternity. Their request was granted and, on October 26, 1927, Alpha Delta Gamma officially charted its Beta chapter, becoming a national fraternity.[5] The fraternity continued expanding to other Catholic colleges and universities and adopted the descriptive "National Catholic-College Fraternity." This was eventually changed to "National Catholic Social Fraternity" when the organization began expansion to non-Catholic colleges and universities.

Alpha Delta Gamma has remained a small national fraternity, with a total of thirty-two collegiate chapters, fourteen of which are active. Most chapters are located at Catholic universities, but there are no religious requirements for membership.
