Social clubs have a rich history at Abilene Christian University; Since 1919, ACU has been home to 29 local fraternities and sororities. Members form long-lasting friends as they participate together in events such as Sing Song, service projects, retreats, formal social events, and devotionals. They give students opportunities to develop long-lasting friendships. Students involved in club are encouraged to value academic excellence. They evolved from two campus societies established in 1907 for social connection: Argos and Argens. Those two groups became the Hardings and the Zellners in 1913.
