Women’s Equality Day is celebrated annually on Aug. 26 to commemorate the adoption of the 19th Amendment in 1920, which guaranteed all women the right to vote, and to honor the hard-fought victory of the women’s suffrage movement.

A resolution designating Aug. 26 as Women’s Equality Day was approved by Congress on Aug. 16, 1973. On that same day, President Richard Nixon issued a proclamation to note the continuing fight for equal rights. Every president since has issued a similar official announcement.

It has been a century since women were given the right to vote. The women’s equality movement has continued to grow and change and is now about more than the right to vote. Organizations around the world are working toward improvements in education and employment, suppression of violence and reduction of discrimination based on gender.
