As President of the nation's largest women's suffrage organization when the 19th Amendment was ratified, women's voting rights are part of Catt's legacy. The 19th Amendment enfranchised approximately 27 million American women. The amendment extended to women of all races who were not disenfranchised for other reasons. It remains the largest single extension of suffrage in American history. This included three million African American women of voting age, approximately 500,000 of whom lived in the 34 states outside the Deep South. By 1960, the last Census before the Voting Rights Act was passed, more than two million African American women in these 34 states were enfranchised.
