The Chi Chi chapter of Sigma Chi was originally chartered in 1879 at Southern University in Greensboro, Alabama. The charter was held until 1882, and remained inactive until 1993 when Sigma Chi was brought to the Hilltop at Birmingham-Southern College. The chapter was allowed to keep its original Greek letter chapter designation, Chi Chi, upon reinstallation.
History of Sigma Chi (from Wikipedia):
The founding of Sigma Chi began as the result of a disagreement over who would be elected Poet in the Erodelphian Literary Society of old Miami University in Ohio.
Several members of Miami University's Delta Kappa Epsilon chapter (of which all but one of Sigma Chi's founders were members) were also members of the Erodelphian Literary Society. In the fall of 1854 this society was to pick its Poet, and a member of Delta Kappa Epsilon was nominated for the position. He was supported by five of his brothers, but four others (Caldwell, Jordan, Runkle, and Scobey) felt that he lacked the required poetic talent. These men instead chose to give their support to another man who was not a member of the fraternity. Bell and Cooper were not members of Erodelphian, but their support for the dissenting four was unequivocal. The chapter had twelve members and so was evenly divided. Other differences might have been forgotten, but both sides saw this conflict as a matter of principle and over the next few months there came a distancing of their friendship.
The matter came to a head in February 1855, when, in an attempt to seal the rift, Runkle and his companions planned a dinner for their brothers. The feast was prepared, and the table was set, but only one of the men who supported the DKE member as poet arrived, Whitelaw Reid. With him Reid brought a stranger. The six learned that the stranger was an alumnus of DKE from a nearby town.
My name is Minor Millikin; I live in Hamilton", said the man. "I am a man of few words." Reid had told Millikin his side of the dispute, and the two were present to lay down punishment on Runkle, Scobey, and the rest. The leaders of the rebellion (Runkle and Scobey) were to be expelled from the fraternity. The other four, after being properly chastised, would be allowed to stay a part of the group.
At the announcement of the punishment, Runkle stepped forward. He pulled off his Deke pin, tossed it to the table, and said, "I didn't join this fraternity to be anyone's tool! And that, sir", addressing Millikin, "is my answer!" Runkle stalked from the room and his five brothers followed. One final chapter meeting was held, at which the chapter was six-to-six divided on the issue of expulsion. The parent chapter at Yale University was contacted, and all six men were formally expelled.
The six men soon associated themselves with William Lewis Lockwood, a student from New York who had not joined a fraternity. Lockwood's natural business acumen helped to organize the fraternity in its early years. On June 28, 1855 (Commencement at Old Miami), the Sigma Phi Fraternity was founded.
The theft of the Constitution, Ritual, Seals, and other records from Lockwood's room in Oxford in January 1856 necessitated the change of the name of the fraternity to Sigma Chi. Eventually, this action could have been forced upon the group as there was already a Sigma Phi Society in the collegiate world.
Much of Sigma Chi's heraldry is inspired by the legendary story of the Emperor Constantine from the Battle of Milvian Bridge against Mexentius. Notably, the White Cross and the motto "In Hoc Signo Vinces" are evidence of the Constantine link. Although many of the symbols of Sigma Chi relate to Christianity, Sigma Chi is not a religious or Christian fraternity.
