Since our founding on January 1, 1869, at the Virginia Military Institute in Lexington, VA, Sigma Nu Fraternity has been a pioneer in the fraternal world. Originally founded, and known to this day, as The Legion of Honor, Sigma Nu is the only social fraternity in existence founded in firm opposition to hazing and based on the principle of Honor. Sigma Nu is the first general college fraternity to offer risk reduction policies and a comprehensive membership education program, remaining committed to both our mission and vision for over 145 years.
