Like the members of the Sigma, a majority of the members of the Chapter of Phi Iota Alpha of the University of Louisiana, disillusioned with character given to their brotherhood, withdrew from the Fraternity and, in April, 1939, founded Sigma Iota Alpha, a fraternity composed of Latin students of that University. As it was to be expected this new grouping was received with distrust by the other Latin fraternal organizations at the university. Since Phi Sigma Alpha was organized in Puerto Rico with ideals similar to those of the Sigma Iota Alpha in Louisiana, and since both organizations were the product of almost identical former brotherhoods, negotiations were immediately started to merge the two brotherhoods into one. This was decided in a convention celebrated on September 10, 1939, at the University of Puerto Rico, organizing themselves as "Fraternidad Sigma" (Sigma Fraternity) with two ramifications: Phi Sigma Alpha Zone in Puerto Rico and Sigma Iota Alpha Zone in Louisiana (Later the USA Zone's name was changed to Phi Sigma Beta Zone and came to include other universities in north Louisiana).
