Chi Rho
Gamma Delta Chi ("GDX") can trace its history to two fraternities on the Dartmouth College campus, Phi Kappa Sigma and Alpha Chi Rho. Gamma Delta Epsilon, a local fraternity, was founded in 1908, disbanded in 1912, but was reformed in 1921. In 1928, the Gamma Delta Epsilon house sought to establish itself as a chapter of a national fraternity and obtained a charter from the Phi Kappa Sigma national fraternity, becoming its "Kappa chapter". Epsilon Kappa Alpha, was established as a local fraternity on the Dartmouth campus in 1915. As with Gamma Delta Epsilon, Epsilon Kappa Alpha sought to become a chapter of a national fraternity and was granted a charter as the "Phi Nu chapter" of Alpha Chi Rho in 1918. The Dartmouth chapters of Alpha Chi Rho and Phi Kappa Sigma found themselves in similar financial situations in 1934. Both chapters owned prime lots near campus that lacked adequate residential structures. The two fraternities decided to share their resources and in 1935 merged to become a new local fraternity, Gamma Delta Chi. The lot formerly owned by Alpha Chi Rho was sold to the Church of Christ at Dartmouth where a new church building was constructed, and the revenue from the land sale supported the construction of a new house at Gamma Delta Chi's current location. (The Alpha Chi Rho national fraternity would later re-establish a "Phi Nu chapter" at Dartmouth in 1956 as a separate fraternity from Gamma Delta Chi. This second "Phi Nu chapter" would dissociate from the Alpha Chi Rho national in 1963 to become a local fraternity named Alpha Chi Alpha.)
