I am mad that y'all didn't let the official Delta historian answer.
FutureGreek1, yes we were founded at the Crimson Tide. And yes that is where we got one of our colors and our official mascot. Good analyzing.
We were Alabama's second Black sorority and they welcomed us with open arms. The feeling has been mutual every since.
As for the AKAs, they too were founded at Alabama. But because they did not honor the school by using their color, some of them broke off and founded Delta.
Hopethis helps. And Mr. I--stay out of Delta business!!!
