The "bonnet rouge" on a spear was proposed as a component of the national seal on 22 September 1792 during the third session of the National Convention. Following a suggestion by Gaan Coulon, the Convention decreed that convicts would not be permitted to wear the red cap, as it was consecrated as the badge of citizenship and freedom. In 1792, when Louis XVI was induced to sign a constitution, popular prints of the king were doctored to show him wearing the "bonnet rouge". The bust of Voltaire was crowned with the red bonnet of liberty after a performance of his "Brutus" at the Comédie-Française in March 1792.
