Answer:
After a year of harsh rule by Robespierre, many of the revolutionary leaders had had enough of the Terror. They turned on Robespierre and had him arrested. He was executed, along with many of his supporters, by guillotine on July 28, 1794. The intensification of the 'Reign of Terror' and Robespierre's autocracy made him increasingly unpopular. French military successes served to undermine the justification for such ruthlessness and a conspiracy was formed to overthrow Robespierre. On 27 July 1794, he was arrested after a struggle.
