Due to World War II, all fifteen chapters went inactive in late 1942. Many schools had such low enrollments, that the state legislatures considered closing them permanently. The war also prevented the 1943 Grand Chapter Convention, where the election of new National Officers would have taken place. It was agreed that the current officers would guide the fraternity and its ultimate reorganization until the next Grand Chapter meeting could be held. By the fall of 1946, all but one of the chapters prior to the war were reactivated with the exception of Mu Chapter at State Teachers College, Slippery Rock, Pennsylvania. However, as history would show, it would take decades for the fraternity to recover the momentum that it had gained throughout the 1920s and 30s.
