The first publication of Le Père Duchesne occurred in September 1790 and opened a new period in his life. The polemic articles he penned were written with wit, but were also violent and abusive, and purposely couched in foul language in order to appeal to the sans culottes. Street hawkers would yell: Il est bougrement en colère aujourd’hui le père Duchesne! (Father Duchesne is very angry today!).
Initially, 1790-1791, Le Père Duchesne supported a constitutional monarchy and was even favorable towards King Louis XVI and the opinions of the Marquis de La Fayette. His violent attacks of the period were aimed at Jean-Sifrein Maury, a great defender of papal authority and the main opponent of the Civil Constitution of the Clergy.
With the king's flight to Varennes his tone significantly hardened. Starting in 1792 the Paris Commune and the ministers of war Jean-Nicolas Pache and, later, Jean Baptiste Noël Bouchotte bought several thousand copies of Le Père Duchesne which were distributed free to the public and troops. He referred to Marie Antoinette as 'the Austrian bitch' and addressing Louis XVI as 'Monsieur Veto, the drunken drip.'
