Olympe de Gouges was a very early French feminist who was active during the French Revolution and was killed by Robbespierre during his reign of terror. She was particularly noteworthy because her activism could be regarded as an early form of intersectional feminism, because she fought not only for the rights of women, but also opposed slavery and the prison system of her time, as well as fighting for children’s rights and social security.
