Les Mignons was a term used by polemicists in the toxic atmosphere of the French Wars of Religion and taken up by the people of Paris, to designate the favourites of Henry III of France, from his return from Poland to reign in France in 1574, to his assassination in 1589, a disastrous end to which the perception of effeminate weakness contributed. The mignons were frivolous and fashionable young men, to whom public malignity attributed heterodox sexuality, rumors that some historians have found to be a factor in the disintegration of the late Valois monarchy. According to the contemporary chronicler Pierre de l'Estoile, they made themselves "exceedingly odious, as much by their foolish and haughty demeanour, as by their effeminate and immodest dress, but above all by the immense gifts the king made to them." The Joyeuse wedding in 1581 occasioned one of the most extravagant displays of the reign. The faction of the Malcontents, headed by François, duc d'Alençon, created duc d'Anjou in 1576— the presumed heir as long as Henry remained childless— appear to have stirred up the ill will of the Parisians against them. From 1576 the mignons were attacked by popular opinion, and some historians have credited without proof the scandalous stories of the time. Some fourteen favourites were singled out, including François d'Espinay, seigneur de Saint-Luc, who had accompanied Henry to his "exile" in Poland and was rewarded now with the château de Rozoy-en-Brie and the governorship of Brouage; but the best known of the mignons, the archimignons in L'Estoile's Registre-Journal, who monopolised access to the king after the death of Henri's brother and heir the duc d'Alençon were Anne de Joyeuse, baron d'Arques, created duc de Joyeuse and Jean Louis de Nogaret de La Valette, created duc d'Épernon. The appearance of the mignons on Henry's visits in July 1576 to the parishes of Paris to raise money to pay for the provisions of the Edict of Beaulieu, occasioned a report by L'Éstoile: L'Éstoile added "they wear their hair long, curled and recurled by artifice, with little bonnets of velvet on top of it like whores in the brothels, and the ruffles on their linen shirts are of starched finery and one half foot long so that their heads look like St. John's on a platter." The figure of Ganymede was employed in scurrilous sonnetry, but the subtext of criticism within the court was most often that the mignons were not drawn from the cream of noble families, as had been the court favourites of his late brother Francis II or their father Henry II, but from the secondary nobility, raised up to such a degree that the social fabric appeared to be unnaturally strained.
In April 1578, the rival court parties of Henry III and Henry, Duke of Guise decided to reenact the battle of the Horatii and the Curiatii. On 27 April, Jacques de Caylus, Louis de Maugiron and Jean d'Arcès engaged in a mock battle with Charles de Balzac, Ribérac, and Georges de Schomberg. Maugiron and Schomberg were killed in the fighting, Ribérac died of wounds the following noon, d'Arcès was wounded in the head and convalesced in a hospital for six weeks, while Caylus sustained as many as 19 wounds and died after 33 days of agony. Only Balzac got off with a mere scratch on his arm. This meaningless loss of life impressed itself on the public imagination. Jean Passerat wrote an elegy, Plaintes de Cléophon, on the occasion. In the political treatiseLe Theatre de France the duel was invoked as "the day of the pigs" who "killed each other in the precinct of Saint Paul, serving him in the Muscovite manner". Michel Montaigne decried the event as "an image de cowardice", and Pierre Brantôme connected it with the deplorable spread of the Italian and Gascon manners at Henry's court. The incident accelerated the estrangement between the two Henrys.
