One major achievement of the women's rights movement in the 20th century was the passage of the 19th Amendment to the U.S. Constitution in 1920, which granted women the right to vote. This landmark victory followed decades of advocacy, protests, and activism by suffragists such as Susan B. Anthony and Elizabeth Cady Stanton. The women’s suffrage movement significantly shifted societal views on gender roles and demonstrated the effectiveness of organized efforts for social change. Gaining the right to vote empowered women politically and socially, allowing them to participate more fully in democratic processes and influence legislation affecting their lives and communities.
