TUSCALOOSA (AP) — The president of the University of Alabama’s Kappa Alpha chapter says the fraternity has canceled its annual Old South parade.

The event has traditionally featured members dressed as Confederate soldiers and waving Confederate flags. Last year’s parade stopped in front of Alpha Kappa Alpha sorority’s house as the historically black group was holding an event celebrating its 35th anniversary. The incident upset many of the group’s alumnae.

Sorority members said they requested an apology from Kappa Alpha members while the trucks were in front of the house but did not receive one. National and local fraternity leaders later apologized.

Following the incident, Alpha Kappa Alpha alumnae sent a letter to UA President Robert Witt asking him cancel all Old South events.
