annual event in the United States, observed on August 26 since its inception in 1971, marking women's advancements toward equality with men. August 26, 1970, marked the 50th anniversary of the passage of the Nineteenth Amendment, which granted American women full suffrage. On that anniversary the National Organization for Women (NOW) called upon women nationwide to “strike for equality.” Women in 40 cities organized demonstrations to protest the fact that women still did not have equal rights. In New York City 50,000 women marched down Fifth Avenue to demonstrate their support of the women's movement and equal rights. Former NOW president Betty Friedan (Friedan, Betty), feminist Gloria Steinem (Steinem, Gloria), and Representative Bella Abzug (Abzug, Bella) addressed the crowd, and the event was extraordinarily successful in demonstrating the breadth of the support for women's rights. In 1971 Congress officially recognized August 26 as Women's Equality Day. Annually since then, women have observed the day with events that celebrate women's progress toward equality.
