175 Moments in Phi Delta Theta History

On December 26, 2023, Phi Delta Theta celebrates 175 years of Friendship, Sound Learning, and Rectitude. Our Cardinal Principles have been the heart of the experience for all who share the letters of Phi Delta Theta. They bring us closer as brothers, teach us lessons, and pave the way for the future of the Fraternity. Along the way, the Fraternity and its people have realized many historical moments that have shaped its future.
