History of Our National Fraternity
Our National Headquarters

Headquartered in Lexington, Virginia, Sigma Nu Fraternity currently has nearly 180 active chapters and colonies on college campuses throughout the United States and Canada, and has initiated over 214,000 members since its founding.
The Sigma Nu National Fraternity was founded in 1869 at Virginia Military Institute by three cadets. Sigma Nu is one of the oldest and largest national fraternities in the nation. Originally founded as the “Legion of Honor,” our founders adopted Honor as a guiding principle. This was a natural move since a rigid code of Honor was already an established tradition of the VMI Corps of Cadets. The Honor system at VMI required each cadet to conform to the duty imposed by his conscience that each act be governed by a high sense of Honor. The vows taken by our three Founders bound them together to oppose hazing at VMI and encouraged the application of the Principle of Honor in all their relationships.
