The Delta Zeta Sorority was officially incorporated on October 24, 1902. Its founding members were Julia Lawrence Bishop, Mary Jane Collins, Alfa Lloyd Hayes, Anna Louise Keen, Mabelle May Minton, and Anne Dial Simmons.
The first National Assembly, with Lloyd as the national president, was held in 1907.
In 1910, Delta Zeta published the first issue of its national magazine, ''The LAMP,'' now issued three times a year.
That same year, the sorority joined the
National Panhellenic Conference.
Throughout the middle of the century, Delta Zeta absorbed four other sororities:
Beta Phi Alpha in 1941,
Phi Omega Pi in 1946,
Delta Sigma Epsilon in 1956, and
Theta Upsilon in 1962; most of these sororities had previously absorbed other, smaller sororities as well.

Controversies

The Delta Zeta national leadership was criticized after ''

'' published an article accusing the national office of moving certain members of the ''Delta chapter'' at DePauw University to alumnae status based on their perceived attractiveness. Founded in 1909, the Delta chapter was the sorority's second-oldest active chapter and its fourth-oldest chapter overall (a "single letter" chapter). Despite its long history at DePauw, the chapter struggled with declining membership and had acquired a negative reputation on campus. As a result, ''Delta chapter'' members voted to request Delta Zeta Sorority to close the chapter due to falling numbers and a lack of interest in recruitment. When notified of the chapter decision, Delta Zeta Sorority arranged a chapter membership review and chapter reorganization rather than closing the chapter completely. Several of the members who were moved to alumnae status, and therefore required to move out of the Delta Zeta house at DePauw, argued that they were moved to alumnae status due to their perceived unattractiveness, weight, or ethnicity and contacted the media.
