LANHAM, Md. (CBSDC) — The Delta Sigma Theta Sorority was founded in 1913 by 22 African-American women at Howard University.

Marching down Pennsylvania Avenue as part of the Woman Suffrage Parade of 1913 was the first public act performed by the group’s founders.

On Thursday, the sisters are coming full circle, as they descend on D.C. to celebrate their centennial with a National Convention, scheduled for July 11 – 17.

D.C. is also the final destination of the Delta Sigma Centennial Celebration torch, which began its journey in Hollywood, Calif. on Jan. 1 and traveled to cities significant to the sorority, going as far away as Tokyo.

“In a significant and historic journey across the country, selected members of the Sorority will carefully carry and pass the Delta Torch as a burning symbol of the passion and commitment of the Sorority’s global reach,” according to the group’s website.
