The famous feminist leader known for her role in women’s suffrage in the early 20th century was Susan B. Anthony. She was pivotal in advocating for women's rights and played a crucial role in the women's suffrage movement in the United States. Alongside her contemporaries like Elizabeth Cady Stanton, Anthony campaigned tirelessly for women's voting rights and co-founded the National Woman Suffrage Association. She was instrumental in organizing events, delivering speeches, and writing extensively to raise awareness about women's issues. Despite her death in 1906, her relentless efforts laid the groundwork for the eventual passage of the 19th Amendment in 1920.
