"Prostitution accordingly not only became a tolerated occupation in many medieval communities, but was even treated in some places as a public utility of sorts. In the fourteenth century many towns carried this principle to its logical conclusion and began to build and operate municipal brothels as a means of regulating the sex trade while realizing a profit from it at the same time. Moral ambiguity concerning the prostitution industry long persisted, and the public policy on the matter still remains controversial in Western societies.Both lawyers and lawgivers typically sought to contain the practice of prostitution by restricting harlots and brothels to specially-designated regions within towns. Municipal statutes, following the decree of the Fourth Lateran Council, often required prostitutes to wear distinctive collectors and types of clothing. The rationale that lawmakers usually proposed to explain such regulations was that they would spare respectable women, especially the wives and daughters of established citizens, from the sexual importuning of randy men. This, in turn, was justified as a means to preserve civic peace and harmony. Municipal authorities also attempted in many places to restrict the practice of prostitution to well-defined and usually marginal regions within their towns. Here again they habitually invoked the public good as a reason for these restrictions, although it seems likely that legislation of this sort may also have served the economic and social interests of landlords and property owners in the more salubrious and desirable neighborhoods of the town.Church leaders and civic authorities alike, moreover, were concerned to provide women who wished to abandon the life of shame with realistic opportunities to do so. Thus, for example Pope Innocent III early in the thirteenth century reversed a long-standing policy that had prohibited good Christian men from marrying prostitutes. Innocent not merely permitted these marriages, but positively encouraged them and promised spiritual rewards for men who married loose women, provided of course that the husbands of former prostitutes kept close watch over their wives to make sure that they remained sexually faithful and did not return to their wanton ways. The prospect of marrying a reformed prostitute may well have been especially alluring to financially disadvantaged men, since successful strumpets occasionally managed to accumulate tidy dowries from the profits of their trade."
