February 26, 1988 marked the beginning of a better social environment at the California Polytechnic State University San Luis Obispo for students who could not relate and identify with the established Greek system. It was on this date that fifteen friends who called each other "Xinaco"(Chinaco), gathered to expressed their ideas on how to incorporate their Latino based brotherhood to the Greek system.

"Xinaco", a Nahuatle word used by the Olmecs, describes an educated, amiable individual who's personality and charisma transcends and enlightens all cultures and social classes. The "Xinacos" meeting resulted in the creation of a new fraternity. A fraternity based on their beliefs of a commitment to "Carnalismo" or brotherhood, the search for knowledge and the retention and pride of culture.

Attempting to be the first non traditional fraternity of it's kind at Cal Poly, San Luis Obispo put a tremendous amount of pressure on each member to make the organization a success because attempts in the past by other groups had failed. Unfortunately, four members were unable to continue. The remaining eleven "Xinacos" Antonio Arreola, Marin Arreola, Nicolas Arreola, Ernesto Garcia, Moises Herrera, Jesse Martinez, Hector Mendoza, Ramiro Ramos, Joel Romero, Alberto Salazar and Antonio Valenzuela ventured forward and with the advice of their advisor, Alurista chose the "Greek letters NAK to enunciate the sound of Nac in "Xinaco" and to correspond with the letters that are formed with the movement of a serpent (the open mouth forming the K). This marked the beginning of Nu Alpha Kappa Fraternity.
