After King Louis was caught he was convicted of treason and was punished by execution. By King Louis being executed, it showed that the revolution was gaining in power and how powerful it was. In 1793, the Convention established the Committee of Public Safety which was a 12 man Committee that worked as the executive branch of the revolutionary government. Girondins and Montagnards were both included in this committee and in May, more moderate Girondins were purged from the Convention, and the more extreme Montagnards took control of the Convention and the Committee of Public Safety. Then the Montagnards used their power to identify their enemy in the revolution. The Committee of Public Safety was necessary because it united all the revolutionists together and progressed towards their goal of equality and justice. Under the direction of Maximilien Robespierre, the Committee of Public Safety executed tens of thousands of people by guillotine in the name of the revolution. At least 300,000 suspects were arrested, 17,000 were officially executed, and many died in prison or without trial (French Revolution, 2018). In addition, the Committee of Public Safety had to mobilize an entire society into a defensive position because they faced internal collapse and external defeat (Mcphee, 2006). The Committee of Public Safety was focused on increasing their size so they established a draft for all men between the ages of 18 and 25, which made the French army increase in size massively. Then the Convention abolished the Gregorian calendar which had Christian associations and replaced it with a more scientific calendar. In July 1794, the Convention overthrew Robespierre and put an end to the reign of terror which is known as the Thermidorian reaction .
