WASHINGTON (CBSDC/AP) — The women of Delta Sigma Theta Sorority retraced the footsteps of their founders who participated in the Women’s Suffrage March of 1913.

Thousands of the sorority’s members, dressed in red and black, commemorated the 100th anniversary of the march and the role the organization’s 22 founders played by marching Sunday along Pennsylvania Avenue to the National Mall.

Delta Sigma Theta Sorority was founded in 1913 by 22 African-American women at Howard University.

Participating in the Women’s Suffrage March was the first public act performed by the group’s founders, according to their official website.

The sorority is one of the largest African-American women’s organizations in the country.
