Delta Sigma Theta Sorority, Incorporated is a prominent African American Greek-lettered organization. It was founded on January 13, 1913 at Howard University in Washington, D.C. by 22 collegiate women who sought to promote academic excellence and provide assistance to those in need.

Throughout its history, Delta Sigma Theta has been deeply involved in social and political activism, advocating for civil rights, women's rights, and economic empowerment in the African American community. The sorority played a significant role in the Civil Rights Movement, with members such as Dorothy Height and Shirley Chisholm leading the charge for racial equality and social justice.

Delta Sigma Theta has also been instrumental in promoting education through scholarships and mentoring programs, as well as addressing pressing social issues such as healthcare disparities, voter suppression, and criminal justice reform.

Today, Delta Sigma Theta Sorority has over 200,000 members and continues to be a powerful force for positive change in Black communities across the United States and beyond.
