A key reason for freeing trade was that King Charles wanted to remove the monopoly of Cádiz, a Spanish port, over trade with the Americas. Cádiz could not supply for the large demand in the Americas. He also wanted to end the Spanish Crown's financial dependence on this monopoly. Free trade was largely supported, notably by important ministers like Gálvez, a Spanish Visitador general, who argued for more commercial deregulation and the end of the monopoly of Cádiz in his paper entitled “Discurso y reflexiones de un vasallo sobre la decadencia de nuestras Indias españoles”. Another supporter of free trade was Esquilache's commercial policy commission, which on February 14, 1765, submitted a report advocating imperial free trade to replace the Cádiz monopoly.
