Which fraternity was the only organized fraternity during the Civil War?

• A. Theta Xi at Rensselaer Polytechnic Institute
• B. Alpha Tau Omega
• C. Sigma Nu
• D. Kappa Alpha Order

Answer: (A)

The key idea is continuity during the Civil War: which fraternity kept its organization active on campus despite the upheaval? Theta Xi at Rensselaer Polytechnic Institute did just that, forming in 1864 and continuing to operate through the war. Because it maintained an organized group on campus while other fraternities had not yet formed or suspended activities, it’s identified as the one fraternity that remained organized during that period. The other fraternities mentioned were founded around or after the war and did not have the same wartime continuity.
