Susan B. Anthony was an American social reformer and women's rights activist who played a pivotal role in the women's suffrage movement. Born into a Quaker family committed to social equality, she collected anti-slavery petitions at the age of 17. In 1856, she became the New York state agent for the American Anti-Slavery Society.

Women's suffrage, or the right to vote, was established in the United States over the course of more than half a century, first in various states and localities, sometimes on a limited basis, and then nationally in 1920 with the ratification of the 19th Amendment to the United States Constitution.
