WASHINGTON (WUSA9) -- The Delta Sigma Theta sorority is celebrating the 100th anniversary of the its founding.

It's the largest African American women's organization in the entire country.

The organization began at Howard University.

Congresswoman Marsha Fudge, a past president of the Deltas says 100 years "means that we have reached the pinnacle that very few organizations or institutions in this country ever reach. When you reach 100 years of age, we're more than a sorority. We are an institution."

The sorority has prided itself on training and teaching young people and standing up for civil and human rights.

The convention lasts until July 17.
