Zeta Phi Beta Sorority, Incorporated was founded on January 16,1920 on the campus of Howard University in Washington, D.C. Our Sisterhood was founded by five lovely pearls.

They stood for scholarship, community service, finer womanhood and sisterly love. Zeta Phi Beta was the first greek-letter ogranization to charter a chapter in Africa (1948). A nonprofit organization, Zeta Phi Beta is incorporated in Washington, D.C. and in the state of Illinois. The dues and gifts of its members support the sorority.

In the year of 1987 there was a meeting in McNulty Hall where a number of ladies gathered to find out more information about Zeta Phi Beta Sorority, Inc. As time went on only nine ladies went on to show there true love to the organization. Finally on March 12, 1988 they became the Prestigum line of sigma Nu Chapter.

Due to the fact that Sigma Nu was denied access to Johnson & Wales University it became a metropolitan "City Wide" Chapter. This means any student attending a college or university in the Rhode Island area may join the Sigma Nu Chapter.
