Robespierre's laws:

1. Law of Maximum
2. Law of Suspects
3. Law of 22 Prairial
4. Law of General Security

Details:

1. Law of Maximum: The Law of Maximum was introduced by Robespierre in September 1793, during the French Revolution. The law set a maximum price for essential goods such as food and clothing, in an attempt to control inflation and prevent hoarding. The law was meant to ensure that all citizens had access to these basic necessities, regardless of their wealth or social status.

2. Law of Suspects: The Law of Suspects was passed in September 1793. It allowed for the arrest and detention of anyone who was suspected of being an enemy of the Revolution. This included anyone who had ever expressed any criticism of the government or the Revolution, even if they had not committed any actual crime. The law was used to justify the arrest and execution of thousands of people during the Reign of Terror.

3. Law of 22 Prairial: The Law of 22 Prairial was passed in June 1794, during the height of the Reign of Terror. It simplified the legal process for prosecuting suspected traitors and enemies of the Revolution. Under this law, anyone accused of treason or other crimes against the state could be tried and convicted without the benefit of a defense lawyer or a fair trial. The law led to an increase in the number of executions during the Reign of Terror.

4. Law of General Security: The Law of General Security was passed in February 1792, before Robespierre came to power. It established a national police force to maintain law and order and prevent crime. The law also gave the government broad powers to arrest and detain suspected criminals without trial. Robespierre used this law to suppress political opposition and to arrest and execute suspected enemies of the Revolution.
