Our History
On December 26th, 1848, Robert Morrison, John McMillan Wilson, and four classmates, known as the "Immortal Six," founded Phi Delta Theta at Miami University in Oxford, Ohio. They created the fraternity's guiding principles and The Bond, which every initiate still signs today. Their vision laid the foundation for a brotherhood that would grow and thrive for generations.
Phi Delta Theta quickly expanded, with its second chapter at Indiana University in 1849. The fraternity's growth was fueled by Walter B. Palmer and George Banta Sr., the "Second Founders," who helped spread Phi Delta Theta across campuses in the late 19th century.
Today, Phi Delta Theta has nearly 190 active chapters and over 180,000 alumni worldwide, continuing to foster lifelong friendships, leadership, and service while making a positive impact in communities.
