Which of the following is NOT one of the founding principles of DKE as related to its Southern heritage?

The founding principles of Delta Kappa Epsilon (DKE) were influenced significantly by their Southern heritage, which included elements like a strong emphasis on military connections and the organization’s notable presence in Southern educational institutions. The reference to founders' diversity indicates the varied backgrounds of those who established the fraternity, contributing to its values and mission.

Cultural celebrations, while important within the fraternity for fostering camaraderie and preserving traditions, do not represent a core founding principle in the context of DKE's Southern heritage. The fraternity's emphasis lies more in its historical ties to military service and Southern schools, making cultural celebrations less relevant when identifying foundational principles. Thus, this choice appropriately highlights an aspect that is secondary to the fraternity's legacy and identity.
