As early as 1940, graduate chapters of Zeta Phi Beta Sorority, Incorporated  began to realize the importance of the prestige, goodwill, and cooperation of women who, for various reasons, were not members of any Greek-letter organization. Under the administration of Lullelia Walker Harrison, 12th International President, the first Amicae auxiliary was organized in Omaha, Nebraska in 1947 making Zeta the first sorority in the National Pan-Hellenic Council to organize an auxiliary group.

Amicae are women who believe in and support the ideals of Zeta Phi Beta Sorority, Inc., but have not earned a college degree. The Zeta Amicae group was established as an official auxiliary of Zeta Phi Beta during the 1948 Grand Boulé (National Convention). The first national charter was issued to Lambda Zeta Chapter as the sponsoring chapter of the Zeta Amicae of Houston, Texas.  Lambda Zeta along with Gamma Omega Zeta and Omicron Gamma Zeta serve as sponsoring graduate chapters. The auxiliary has been involved in the Houston community for over 75 years.

The Zeta Amicae of Houston are always interested in welcoming women who support the ideals and goals of Zeta Phi Beta. Friends and relatives of Zeta Phi Beta members, who have not completed a college degree are especially encouraged to apply for membership.
