In 1789 Camus was elected by the Third Estate of Paris to the Estates-General; he attracted attention by his speeches against social inequalities.
He helped to write and voted for the Civil Constitution of the Clergy, worked to end the practice of paying annates to the papacy, and promoted the annexation of the Vaucluse by France.
[citation needed] Elected to the National Convention by the département of Haute-Loire,[1] he was on a mission outside Paris during the judgment of Louis XVI.
On his return, Camus was sent to Belgium as one of five commissioners of the convention, to the Armée du Nord commanded by General C. F. Dumouriez.
He played an inconspicuous role in the Council of Five Hundred, refusing positions in the Ministry of Finance or of Police.
