In the interim, Louis IX (1226–1270) attempted to ban prostitution in December 1254, with disastrous social consequences and widespread protests. The decree ordered the expulsion of all "women of evil life" from the kingdom and confiscation of their belongings, but simply drove the trade underground. Eventually he was forced to revoke this by 1256. Although still railing against women who were "free with their bodies and other common harlots", he acknowledged the pragmatic desirability of housing them away from respectable streets and religious establishments, and so obliged them to reside outside of the borders of the city walls. His resolve to do away with prostitution was affirmed in a letter of 1269 to the regents, as he set out on the Eighth Crusade, in which he refers to the need to extirpate the evil, root and branch. The punishment for infraction was an 8 sous fine and risking imprisonment in the Châtelet (see below). He designated nine streets in which prostitution would be allowed in Paris, three of them being in the sarcastically named Beaubourg quartier (Beautiful Neighbourhood) (Rue de la Huchette, Rue Froimon, Rue du Renard-Saint-Merri, Rue Taille pain, Rue Brisemiches, Rue Champ-Fleury, Rue Trace-putain,
