National History

Triangle's beginnings came from the desire of some congenial college friends to extend their friendship, not only through college, but also for life. It was in the fall of 1906 that sixteen civil engineering juniors at the University of Illinois began the association that became Triangle Fraternity. These Founders based their organization on the principles of honor, friendship, character, brotherhood, courage, and ideals. They developed their plans quickly, and on April 15, 1907, incorporated Triangle in the State of Illinois. The date of incorporation has been designated as Founders' Day, and Triangle appropriately celebrates it every year at each chapter.

Local History
