Susan B. Anthony was a prominent American social reformer and women's rights activist in the 19th century. Born in 1820, she dedicated her life to fighting for women's suffrage, which means the right for women to vote. Anthony believed that women should have the same rights as men, and she worked tirelessly to promote equality and justice. In 1872, Susan B. Anthony famously cast a vote in the presidential election, which led to her arrest for voting illegally. Her courageous actions helped to inspire future generations of activists, including Elizabeth Cady Stanton and Sojourner Truth, and played a crucial role in the eventual passage of the 19th Amendment in 1920, granting women the right to vote.
