A new national organization was formed at an Alpha Sigma Phi conference at Marietta in 1907, and within a year there were three new chapters: Zeta at Ohio State, Eta at the University of Illinois, and Theta at the University of Michigan. In 1909, Iota chapter was established at Cornell University. In 1910, another convention was held with the members of the former chapters at Yale, Amherst and Ohio Wesleyan University, and a delegation from the Yale Delta Beta Xi fraternity. All of these pledged to anew their loyalty to a restored Alpha Sigma Phi, and soon afterward the chapters Mu at the University of Washington, Nu at University of California, Berkeley, and Upsilon at the Pennsylvania State University were added.
