Black Greek 101 stating that AΦA didn't come first

[DSTCHAOS]

Black Greek 101 provides so much detail regarding this that there should be no need for clarity. Paricularly pay attention to page 30 as it explains the difference between the success of Gamma Phi and that of Alpha Kappa Nu, which are both extinct.

Then the next section of that chapter is entitled "the founding of the major Black Greek Lettered Organizations 1905-1930" for a reason. It begins by discussing the difference in membership-type between the college-graduate Sigma Pi Phi Fraternity and the later founded collegiate and intercollegiate Alpha Phi Alpha Fraternity (and the BGLOs founded thereafter).
