Stanton received a very good education. That was not common for women during that time. She married Henry Stanton, who fought against slavery. They had seven children. She became interested in women's rights when she was at a World's Anti-Slavery meeting in London. She and Lucretia Mott, another activist, were upset because women were not allowed to be a part of the meeting. Because of this, they created their own women's rights meeting.
