# List of San Diego State University fraternities and sororities

The following article is a list of San Diego State University fraternities and sororities, as well as some background history. Greek life at San Diego State University (SDSU) has an extensive history dating back nearly a century and has played an influential role in the university's development over time. Today it encompasses more than forty active chapters of social and culturally-based fraternities and sororities recognized by the university, each represented through one of four governing councils. Honors, service and professional Greek-letter societies also exist and are recognized student organizations at SDSU, though they operate independently of the Office of Fraternity & Sorority Life.

## History

The first fraternity on campus was the local Epsilon Eta, which formed on October 25, 1921. The group maintained strict rules for its members and limited the chapter to twenty male students. The first local sorority, known as Shen Yo, was also established in 1921. By the end of the decade there were six other fraternities and eight sororities. The fraternities and sororities were all local and did not attain national affiliations until after World War II except Alpha Sigma Alpha sorority, chartered in 1932.
On October 10, 1924, the Inter-Fraternity Council (IFC) was founded. The IFC consisted of the nine sororities and the two fraternities that were then on campus. The purpose of IFC was stated as "boosting a high scholarship standard among the members of the fraternal organizations, and of cooperating with the faculty in all matters which lead to the success of the College." The IFC published the grade point averages of fraternities and sororities at the end of each semester, which stimulated a competition for scholastic standing that continues today. On a 3.0 scale, the average GPA (grade point average) for all students at the time was 1.49. For fraternity members, it was 1.35 and for sorority members, it was 1.47. After a couple of years of the co-educational governing organization, the sororities split from the IFC to create their organization, the Inter-Sorority Council, which later became the College Panhellenic Association.
By the mid-1930s, there were eight fraternities and eleven sororities on campus. The campus Greek community expanded to fifteen fraternities and twelve sororities in the 1940s. The post-World War II period saw a frenzy to "go national" among the fraternities and sororities. Between 1947 and 1951, five national fraternities colonized new chapters at SDSU and an additional nine formed chapters through absorbing existing local fraternities on campus. Theta Chi became the first fraternity on campus affiliated with a national organization in 1947. Alpha Xi Delta kickstarted a similar trend for sororities upon chartering in 1949, with nine other national sororities following suit by absorbing the remaining nine local sororities. In 1951, Kappa Alpha Psi fraternity chartered on campus, becoming San Diego State's first African-American Greek organization.
The arrival of national fraternities began the trend of Greek organizations acquiring property for chapter houses. Delta Sigma Phi became the first fraternity to own a chapter house, with Kappa Delta becoming the first sorority to acquire a house shortly thereafter in 1952. The 1950s was a period of steady increase of membership in the Greek community, coinciding with the gradual increase in undergraduate enrollment at the university.
The emergence of the counterculture phenomenon of the late 1960s and early 1970s saw interest in fraternities and sororities decline and the Greek community population dwindled to below 700, with several organizations closing. On April 6, 1978, the Gamma Phi Beta sorority hired a plane to drop marshmallows on fraternity houses during Derby Week, a philanthropy event among the Greek community hosted by the Sigma Chi fraternity. The plane crashed near Peterson Gym on the west side of campus, injuring four students aboard.
In 1983, after a USA Today article reported that SDSU Greeks' GPAs were below the campus average, SDSU tightened restrictions and supervision, and by 1989 grades had increased to slightly above the university average. The Greek system gradually began to grow again in the late seventies following the close of the Vietnam War before spiking in the 1980s, reaching a peak of upwards of 2,900 members in 1988. At this point, there were twenty fraternities and thirteen sororities officially affiliated with the Interfraternity Council and College Panhellenic Association, respectively, as well as six additional independent fraternities and sororities. This made it one of the largest fraternity and sorority systems in the western United States.
The 1990s were a less prosperous time for social fraternities and sororities at the university than the previous decade. A fiscal crisis in California early in the decade severely impacted the California State University system, and SDSU was deeply impacted by budget cuts. A significant decline in enrollment at the university resulted. Several organizations were closed due to operational and conduct issues. Despite the turmoil, the Greek community still experienced substantial growth during the 1990s, though this time it centered primarily around the establishment of numerous culturally-based fraternities and sororities. This led to the establishment of SDSU's fourth Greek governing council, the United Sorority and Fraternity Council on September 24, 1997.
The SDSU Foundation's development of Fraternity Row in 2002, where eight fraternities moved into newly-constructed chapter houses in a 1.4-acre complex adjacent to the newly-constructed Cox Arena (now Viejas Arena). The complex consists of eight free-standing, two-story chapter houses with a private courtyard. The complex provides 61 two and three-bedroom apartment units that overlook the courtyards. The Foundation planned to also construct Sorority Row, a similar project with five free-standing chapter houses, following the completion of Fraternity Row. However, the project was abandoned in 2006 after the Foundation declared the project financially infeasible, citing escalating construction material costs and a lack of commitment from sororities.
In May 2008, the university community was shaken by an investigation into illegal drug use in the college area. Dozens of individuals were arrested in Operation Sudden Fall, including several students who were members of fraternities. Between the spring of 2008 and the spring of 2010, the Interfraternity Council saw its membership drop from sixteen chapters down to just nine, with seven chapters closing during this period all over a variety of misconduct issues. Since this time, the Greek community has experienced steady growth, coinciding with the growth of the university, a renewed interest in Greek life, and increased investment and involvement by alumni and administrators in educational programs for Greek members and organizations.
Today there are a total of more than forty fraternities and sororities at San Diego State University, including both general and culturally-based organizations, represented through one of the four governing councils.

## College Panhellenic Association

The College Panhellenic Association is the governing body of all National Panhellenic Conference general social sororities on campus. According to its website, "the College Panhellenic Association aims to develop and maintain women's fraternity life and interfraternity relations at high levels of accomplishment".
