What measures were taken by Robespierre to bring equality in French society?

Answer 1

None, if you discount killing off a great number of aristocrats as 'enemies of the Revolution'. Bringing about equality was not exactly one of Robespierre's priorities. He came to power at a time when foreign armies were invading France who tried to restore Louis XVI to his former powers, while at the same time large parts of France itself were rebelling against the Revolution. Robespierre totally focused on defeating both the foreign invaders and the rebellious French provinces. This he did, using means (especially in the provinces) that literally drowned the rebellions in an ocean of blood. At the same time, he instituted 'committees' - a sort of kangaroo courts - that convicted thousands of 'enemies of the revolution' to the guillotine. Many of them were noble families, but also thousands of lower-class citizens who had dared to utter even the slightest form of criticism would find themselves imprisoned or summarily executed.

Robespierre's reign very deservedly got named "The Terror". He himself also - after a one-year reign - ended under the Guillotine. He had threatened to 'expose' a long list of names of Members of Parliament who according to him were enemies of the Revolution and who would be carried off to the Guillotine. As a reaction, Parliament immediately moved to have him arrested. He was executed the next day.

The laws bringing about equality under the law for all citizens would be mostly the work of Napoleon.
