Answer 2

Answer:

European powers like Austria viewed the Revolution as a threat, and its course was closely shaped by external events. In February 1793, the Assembly announced a levée en masse or conscription law, triggering widespread unrest in South-West France; in June, popular agitation led by the Jacobin clubs in Paris removed the Girondin government. Led by Maximilien Robespierre, the Committee of Public Safety imposed price controls on food, abolished slavery, established universal suffrage and replaced the Catholic church with the Cult of the Supreme Being.
