On this day in history, October 16th 1793, the Queen of France, Marie Antoinette, is guillotined after being found guilty of high treason by the Revolutionary Tribunal. Marie Antoinette was the daughter of Holy Roman Emperor Francis I and Maria Theresa. She married the heir apparent to the French throne in 1770, and upon Louis-Auguste's ascension, she became Queen. Marie initially was popular with the people, but she gradually fell out of their favour. She was accused of promiscuity and of harbouring sympathies for one of France's greatest enemies, her home, Austria. In addition to this, she was a notorious spendthrift, to the point that many blamed the whole of France's economic problems on her. The decision to execute the king and queen marked an important turning point in the Revolution. Mere revolution was different than regicide, and with this radical decision, the leadership further alienated supporters from their cause and moved closer to a revolution of extreme radicalism. The usurpation of the Revolution by the radical element along with its resulting radical policies caused the Revolution to implode, as men who once supported the Revolution saw it turn into another extreme necessary of overthrow and abolition.
