But these conditions came in by no means with the decline of the Middle Ages. They began early, and gave continuous occasion for complaints and decrees. In 802 Charles the Great issued one of these, which ran this wise: "The cloisters of nuns shall be strictly watched; the nuns may not roam about; they shall be kept with great diligence; neither shall they live in strife and quarrel with one another; they shall in no wise be disobedient to their Superiors or Abbesses, or cross the will of these. Wherever they are placed under the rules of a cloister they are to observe them throughout. Not whoring, not drunkenness, not covetousness shall they be the ministrants of, but in all ways lead just and sober lives. Neither shall any man enter their cloisters, except to attend mass, and he shall immediately depart." A regulation of the year 869 provided: "If priests keep several women, or shed the blood of Christians or heathens, or break the canonical law, they shall be deprived of their priesthood, because they are worse than laymen." The fact that the possession of several women was forbidden in those days only to the priests, indicates that marriage with several wives was no rare occurrence in the ninth century. In fact, there were no laws forbidding it. Aye, and even later, at the time of the Minnesaenger, during the twelfth and thirteenth centuries, the possession of several wives was considered in order.[42] The position of woman was aggravated still more by the circumstance that, along with all the impediments which gradually made marriage and settlement harder, their number materially exceeded that of the men. As special reasons herefor are to be considered the numerous wars and feuds, together with the perilousness of commercial voyages of those days. Furthermore, mortality among men was higher, as the result of habitual excesses and drunkenness. The predisposition to sickness and death that flowed from such habits of life, manifested itself strongly in the numerous pest-like diseases that raged during the Middle Ages. In the interval between 1326 to 1400, there were thirty-two; from 1400 to 1500, forty-one; and from 1500 to 1600, thirty years of pestilence.[43]
