The Esquilache Riots (Motín de Esquilache) occurred in March 1766 during the rule of Charles III of Spain. Caused mostly by the growing discontent in Madrid about the rising costs of bread and other staples, they were sparked off by a series of measures regarding Spaniards' apparel that had been enacted by Leopoldo de Gregorio, Marquis of Esquilache, a Neapolitan minister whom Charles favored.
