Marie Antoinette was the first victim at the start of the reign of terror. After being imprisoned with her children she was executed at the guillotine.
Civil liberties were suspended. The Convention ordered that "if material or moral proof exists, independently of the evidence of witnesses, the latter will not be heard, unless this formality should appear necessary, either to discover accomplices or for other important reasons concerning the public interest."
"Suspend civil liberties!!"
Robespierre, the mastermind of the reign of terror, was arrested and sent to the guillotine the next day, the last victim of the Reign of Terror.
