Treason
from Latin 'traditio,' meaning handing over or betrayal

Treason is the act of betraying one's country or ruler, especially by helping enemies or working to destroy the government. During the French Revolution, the definition of treason grew very wide, and authorities accused people of treason for actions as small as speaking against the government or failing to report a suspected enemy. The Law of Suspects, passed on September 17th, 1793, allowed officials to arrest almost anyone they decided was disloyal, making treason a charge that thousands of ordinary people faced.

"King Louis XVI was put on trial for treason in December 1792 because the new republic accused him of plotting with foreign enemies against France, and he was executed on January 21st, 1793."

Reign of Terror – Maximilien Robespierre

After the execution of Marie Antoinette, the French Revolution continued down a violent path as the Reign of Terror grew and became even more extreme.  This is when Maximilien Robespierre began his own rise to power within the revolution.  He was the head of the Committee of Public Safety, which was the executive committee of the National Convention, and would become well known for its role in carrying out the Reign of Terror.  For many months throughout 1794, Robespierre battled against other revolutionaries in the National Convention by questioning each of their loyalties towards the revolution.  For example, he accused many people of being domestic threatsEnemies seen as coming from inside the country rather than from foreign nations. to the continuation of the revolution.  It is during this time that many prominent revolutionaries within the National Convention were guillotined for their perceived betrayal to the revolution and Robespierre maneuvered his way to the head of the convention.  For example, when Georges Danton, a leading revolutionary, called for an end to the Reign of Terror he was the next to face the guillotine.  Finally, on June 4th, 1794, Robespierre was elected the president of the National Convention.

Robespierre then declared a new religion called the Supreme Being and carried out a series of celebrations based around the new faith.  On June 8th, 1794, Robespierre oversaw the Supreme Being Festival in Paris that would be celebrated based on a new calendar.  Some members of the National Convention and Committee of Public SafetyThe executive committee of the National Convention that directed the Reign of Terror under Robespierre. were visibly upset with the celebration and the actions of Maximilien Robespierre.  In fact, Robespierre had begun to make many enemies within the revolution after he claimed to have a list of people that were enemies of the revolution.  By threatening to release the names, Robespierre angered others who began to work against him and accuse him of acting like a dictator.

Based on his actions and threats the National Convention voted to arrest Robespierre.  On July 28th, 1794, soldiers stormed into where Robespierre was staying.  As the soldiers arrived, he attempted to commit suicide by gunshot to the head, but was instead only injured in the jaw, shattering it.  For the rest of the day, Robespierre was held captive until he was guillotined without a trial that same afternoon.  With his death, the fear and paranoia of the revolutionaries ended and the Reign of Terror was over.  After the execution of Robespierre and the excess of the Reign of Terror, the National Convention was replaced by the Directory in 1795.
