The 1918 convention split into two separate meetings, Union College, University of Connecticut, University of Vermont, and University of New Hampshire delegates retiring. Clarence Dexter Pierce, a member of the University of Vermont Commons Club, successfully sponsored a resolution to declare the Federation a Greek-letter fraternity, with its attendant structure and selectivity. The Commons Clubs at the University of Vermont, University of New Hampshire, and University of Connecticut ratified the plan, forming what is now the Phi Mu Delta national fraternity. While the Union College Commons Club intended to join its counterparts in organizing Phi Mu Delta, the group instead elected to refound the Alpha Charge of Theta Delta Chi in 1923 because of pressure from its alumni.
