But these conditions by no means made their appearance only at the decline of the middle age. They appeared at an early date and gave cause for constant complaints and ordinances. Thus Charlemagne issued an ordinance in the year 802, in which it says: “the nunneries shall be closely guarded. The nuns shall not roam about but shall be carefully watched, neither shall they live in discord and quarrels with one another, and under no circumstances shall they disobey their mothers superior. Where they have monastic rules they shall absolutely abide by them. They shall not be given to covetousness, drunkenness and prostitution, but shall lead a just and temperate life. Neither shall any man enter their convent except to attend mass, and then he shall immediately depart again.” Another ordinance of the year 869 declared: “if priests keep ~several~ wives or shed the blood of Christians or heathens, or break the canonical law, they shall be divested of their priesthood because they are worse than the laity.” The fact that in those days the priests were forbidden to have several wives, shows that in the ninth century polygamy was not rare. Indeed there were no laws forbidding it. Even later, at the time of the minnesingers, during the twelfth and thirteenth centuries, it was not considered objectionable to have several wives. In a poem by Albrecht of Johansdorf in the collection “Love-songs’ Springtime,” we find the following stanza:[33] Particularly detrimental to the moral condition of the age were the crusades, that kept tens of thousands of men away from their homes for years, and led them to become acquainted with customs in the Eastern Roman empire that had until then been unknown in Western Europe. The position of women became especially unfavorable, not only as a result of the many hindrances to marriage and permanent residence, but also because their numbers by far exceeded the male population. The chief cause of this was the numerous wars and the fact that commercial traveling in those days was a dangerous undertaking. Moreover the death rate among men was higher than among women, as a result of their intemperate living, which was especially manifested during the plague that frequently ravaged the population in the middle age. Thus there were 32 plague years in the period from 1326 to 1400; 41 from 1400 to 1500, and 30 from 1500 to 1600.[34]
