Not until the eighteenth century did a slow improvement of matters set in. The absolute Princes had the liveliest interest, with the view of raising the standard abroad of their rule, to increase the population of their territories. They needed this, partly in order to obtain soldiers for their wars, partly also to gain taxpayers, who were to raise the sums needed either for the army, or for the extravagant indulgences of the court, or for both. Following the example of Louis XIV of France, the majority of the then extraordinarily numerous princely courts of Germany displayed great lavishness in all manner of show and tinsel. This was especially the case in the matter of the keeping of mistresses, which stood in inverse ratio to the size and capabilities of the realms and realmlets. The history of these courts during the eighteenth century belongs to the ugliest chapters of history. Libraries are filled with the chronicles of the scandals of that era. One potentate sought to surpass the other in hollow pretentiousness, insane lavishness and expensive military fooleries. Above all, the most incredible was achieved in the way of female excesses. It is hard to determine which of the many German courts the palm should be assigned to for extravagance and for a life that vitiated public morals. To-day it was this, to-morrow that court; no German State escaped the plague. The nobility aped the Princes, and the citizens in the residence cities aped the nobility. If the daughter of a citizen's family had the luck to please a gentleman high at court, perchance the Serenissimus himself, in nineteen cases out of twenty she felt highly blessed by such favor, and her family was ready to hand her over for a mistress to the nobleman or the Prince. The same was the case with most of the noble families if one of their daughters found favor with the Prince. Characterlessness and shamelessness ruled over wide circles. As bad as the worst stood matters in the two German capitals, Vienna and Berlin. In the Capua of Germany, Vienna, true enough, the strict Maria Theresa reigned through a large portion of the century, but she was impotent against the doings of a rich nobility, steeped in sensuous pleasures, and of the citizen circles that emulated the nobility. With the Chastity Commissions that she established, and in the aid of which an extensive spy-system was organized, she partly provoked bitterness, and partly made herself laughable. The success was zero. In frivolous Vienna, sayings like these made the rounds during the second half of the eighteenth century: "You must love your neighbor like yourself, that is to say, you must love your neighbor's wife as much as your own;" or "If the wife goes to the right, the husband may go to the left: if she takes an attendant, he takes a lady friend." In how frivolous a vein marriage and adultery were then taken, transpires from a letter of the poet Ew. Chr. von Kleist, addressed in 1751 to his friend Gleim.
