Delta Sigma Theta is an international historically Black sorority. It was founded at Howard University in 1913. The sorority has more than 1,000 collegiate and alumnae chapters located in the United States, Canada, England, Japan (Tokyo and Okinawa), Germany, the Virgin Islands, Liberia, Bermuda, Jamaica, The Bahamas, South Africa, South Korea and Nigeria.
In the early days of the sorority, many chapters were chartered as citywide chapters and included both graduate and undergraduate members. Others, such as Alpha Sigma, Beta Beta, Delta Sigma, Gamma Sigma, Epsilon Sigma, Omicron Sigma, Sigma Sigma, and Theta Sigma (Original) were chartered as alumnae-only chapters. Over time, alumnae chapters split from the mixed chapters. At that time, many city-wide chapters went dormant, with new collegiate chapters forming on specific campuses. In the 1970s, the sorority eliminated mixed chapters.
