Spelman College in Atlanta Georgia (
www.spelman.edu) was founded in 1881 and did not get sororities until the late 70s (If I remember correctly, it was around'78 or '79) because the administration felt that it would be devisive to the universal Spelman Sisterhood. Before that time Spelman women sometimes joined as "general" members at their sororities national convention.
All four NPHC sororities have charters at Spelman or students have the ability of joining through a citywide chapter, but I am not sure if all are currently active.
There are several other Spelman Alumna that post on this board that might be able to give more insight
