Lambda Theta Alpha Latin Sorority, Inc. (ΛΘΑ) was established in 1975. The idea for Lambda Theta Alpha began in the 1970s, when colleges and universities experienced an influx of Latino enrollment; the organization was founded at Kean University by seventeen women of Latin, Caribbean, and European descent. The sorority is Latin by tradition, not by definition in that it remains open to women of all races and ethnicities. It is a social organization that stresses social justice and activism.
