Phi Tau was thus formed in May 1956. Ironically, it still won the debate on the national level: Phi Sigma Kappa voted at its next convention, just two months later in July 1956, to rescind the "Gentleman's Agreement," and with this action its chapters became free to admit members of all races. It had lost reactionary Tau, but, Phi Sig, to its credit, became one of the first national fraternities to put to rest strife over race. That same year, 1956, its Phi chapter at Swarthmore pledged a black man from the Gold Coast, with no reaction from national leadership. Many national fraternities struggled with this issue into the 1980s.
