Who was Olympe de Gouges?

Olympe de Gouges was a feminist—often called the first feminist—and social activist who came to prominence during the French Revolution. Born in a small town in Southern France, she moved with her daughter to Paris after her husband passed away. It was there that she changed her name from Marie Gouze to the name by which she's known today. At that time in French society, there weren't many career opportunities for women. Nevertheless, Gouges managed to establish herself as a woman of letters, an intellectual who actively participated in the often intense political debates of the day. She proved herself a gifted writer, publishing plays, novels, and of course political articles. Such literary activity was very rare for a woman in that era; once again, Gouges had shown herself ahead of her time.
For a woman as politically involved as Gouges, the French Revolution was inevitably an event of great significance. She wholeheartedly supported the Revolution, but quickly established herself as a forthright critic of its treatment of women. Despite its rhetoric of liberty and equality, the various stages of the Revolution systematically excluded women from public life. Olympe de Gouges's feminist ideas found their most systematic expression in her Declaration of Women's and Female Citizens' Rights. Here, Gouges used her exceptional literary talents to argue for the complete emancipation of women and the unconditional equality of the sexes.
Not surprisingly, Gouges's ideas were hugely controversial, challenging as they did the entrenched prejudices of even the most radical of male revolutionaries. She soon earned a large number of enemies on account of her vocal activism, which found expression not just in her campaign for women's rights, but also in her call to abolish slavery and the death penalty. It was the latter that led her to oppose the death sentence passed on Louis XVI.
Gouges continued to throw herself into political activity with ever greater passion and resolve. She was a supporter of the Girondin faction in the National Convention, which put her at odds with the more radical Jacobins. Despite the growing danger and violence of French political life, Gouges pressed on with her work, fearlessly attacking leading Jacobin figures such as Marat and Robespierre. After the fall of the Girondins, Olympe de Gouges was arrested on a trumped-up charge. The Reign of Terror was just beginning, and opponents of the new Jacobin regime were being rounded up and, in many cases, sent to the guillotine. Gouges defended herself with great courage at her subsequent trial, but she never stood a chance of acquittal; her execution was a foregone conclusion. And so she went to the guillotine on 3rd November, 1793, at the age of 45, convicted of sedition and the patently false charge of wanting to restore the monarchy.
