Delta Sigma Theta (ΔΣΘ) is a not-for profit Greek-lettered sorority of college-educated women who perform public service and place emphasis on the African American community. Delta Sigma Theta Sorority was founded on January 13, 1913, by 22 collegiate women at Howard University. These students wanted to use their collective strength to promote academic excellence and to provide assistance to persons in need. The first public act performed by the Delta Founders involved their participation in the Women's Suffrage March in Washington D.C., March 1913. Delta Sigma Theta was incorporated in 1930. Today, Delta Sigma Theta Sorority is the largest African-American Greek-lettered sorority in the world. Membership in Delta Sigma Theta is open to any woman who meets the membership requirements, regardless of religion, race, or nationality. Women may join through undergraduate chapters at a college or university, or after acquiring a college degree through an alumnae chapter.
A sisterhood of more than 300,000 predominantly Black college-educated women, the sorority currently has over 1,000 chapters located in the United States, England, Japan (Tokyo and Okinawa), Germany, the Virgin Islands, Bermuda, the Bahamas and the Republic of Korea.
Delta Sigma Theta is a member of multiple organizations, including the National Pan-Hellenic Council (NPHC) – an organization of nine international Greek-letter sororities and fraternities - as well as the NAACP and the National Council of Negro Women (NCNW). The current 24th national president is Cynthia M. A. Butler-McIntyre.
The organization will celebrate its 100th birthday with a float entitled "Transforming Communities through Sisterhood and Service" in the 2013 Tournament of Roses Parade in Pasadena, CA.
