The success of the Wesleyan Commons Club inspired the founding of similar organizations at Dartmouth College, Middlebury College, and Norwich University. These four formed the National Federation of Commons Clubs in 1906, which would add thirteen additional members by 1918 as well as numerous non-aligned Commons Clubs on campuses throughout the United States and Canada. Along with the increase in chapter memberships, went a great many improvements, following the easiest course in imitation of the older Greek-letter societies which were close at hand in every college, rather than in sticking to original principles or in making novel but difficult improvements. The Commons Clubs adopted, one after the other, most of the characteristics of the Greek-letter fraternities, not, however, without a fight at every adoption by the sterner, more democratic element in every chapter. The innovations consisted of yearly conventions, an annual magazine, initiation and installation rituals, robes, secret hand grips, badges, pennants, private fraternity houses, alumni organizations, and the like.
