Delta Zeta Sorority was founded at Miami University in Oxford, Ohio, in 1902. It was the first sorority to be founded at the university.
Six women, Alfa Lloyd, Mary Collins, Anna Keen, Julia Bishop, Mabelle Minton and Anne Simmons bonded as they faced the challenges of starting a sorority on a male-dominated campus.
Delta Zeta now has over 260,000 alumnae and collegiate members in the United States and Canada.
The Xi Lambda chapter was founded at the University of San Francisco in 1983 and it is the oldest Greek organization on campus.
