Caucasian race
Membership in Alpha Kappa Psi was originally restricted to men who were "of the Christian faith and Caucasian race". By 1950, the restrictive clause in the fraternity's constitution was beginning to stir controversy on some college campuses. At the 1950 Alpha Kappa Psi Convention in Minnesota, delegates voted 66–44 in favor of dropping the restrictive membership clause from the national constitution.
