The twenty-one deputies of the National Convention guillotined on October 31, 1793 have been traditionally considered as Girondin deputies, removed from power by their Montagnard opponents. The biographical study of Charles Louis Antiboul, deputy of the Var, however, challenges this assertion as lacking in precision. This research highlights the complexity inherent in the classification of certain deputies, who seem to escape the classic tripartite division of contemporary political positions. The non-partisan approach advanced by Antiboul, whose sole aim was to defend the common good, underscores a specific way of positioning oneself politically. The actual reasons behind the death sentence of the Tropezian appear to be twofold. These probably originated in his resolute defense of the department of the Var, which was accused of federalism. And his interrogation by the Marseilles federalists brought about his downfall, because he was suspected of colluding with the « rebels ».
