History
The sorority that pioneered the Greek world movement for women on the island was established in the University of Puerto Rico, Río Piedras campus in October 1927. The founding sisters were Carmen Rosa Janer, Laura Muñoz, Emma Colón, Aida González, María Padial, Carmen Belén Cruz, Alicia Rivero, Luz Vilá, María Luisa Márquez, Luz Vilariño, Georgina Pastor, Mercedes Fernández, Ramona Santana, Ligia Noya, María Antonieta Delgado, Laura Cesteros, Blanca Martorell, Dolores Gutiérrez de Arroyo, Encarnación Rodríguez, Celia Machese, Sofía Oronoz, Josefina Gutiérrez, Sara Irizarry, María Inés Dávila and Ana María Santana. Since many sisters were graduating by 1930 the need for an alumni chapter was evident, thus the Capitulo Pasivo was founded; this chapter is now called Zona Alpha Alumnae.

By September 13, 1946, the Beta chapter was established at the College of Agriculture and Mechanic Arts in Mayagüez, Puerto Rico. The first Beta sisters were Delia González, Maita Bravo, Andreita Martínez, and Rochie Sabater. As a result of the Beta chapter, the Río Piedras university chapter came to be called Alpha chapter.

In June 1950, sorority sisters at Universidad Católica de Santa María, later called Pontificia Universidad Catolica de Puerto Rico, organized the Gamma chapter, its first president was Betty Zapater de McConnie. The chapter was officially recognized by University Authorities by November 1955. By the early 1960s, sisters at the Inter American University at San Germán organized the Delta chapter, it was led by Martita Mercado, Sally Zaragoza, Laira González Rigau and Berníe Pabón.

Two years later, Mu sisters led by Leila Padilla de Balaguer and Katherine Morell de Domínguez at Arecibo requested a charter for the Epsilon chapter This chapter closed and was later re-opened in 1985. Since so many chapters were being created by 1950 a central governing body was created called Honorable Consejo Supremo.. Its first president was Judith Mercader de Sifre.

Two alumni chapters, Chi Alumni in Cabo Rojo and Gamma Alumnae in Ponce, were established; both chapters were closed. Nevertheless, alumni chapters or "zonas" were then established for sisters who had graduated, were married, or had other interests than those of the student sisters. The first Zona was established in Ponce in 1979 and called Zona Ponce. In San Juan. the alumni chapter was reopened as Zona Alpha Alumnae. By 1985, the Zona Beta was founded in Mayagüez. In1989, Zona Epsilon was founded in Arecibo. In 1992, Zona Phi Alpha was founded in San Juan, and in 1993, Zona Delta.formed in San Germán. Zona Orlando was founded in October 2016, with approximately 70 members living in Florida.
