In the larger cities, which were not the residence of princes, the position of the nobility was very different. In Hamburg, Luebeck, and Bremen, the nobles had no political weight; on the other hand, at Nueremberg, Frankfort-on-the-Maine, Augsburg, and Ulm, the old race of nobility lived in proud isolation from the rest of the citizens. Worst of all were the Nuerembergers, who considered it even degrading to carry on commerce. Of two noble societies of Frankfort-on-the-Maine, one, the house of Alten-Limpurg, required of every member who presented himself for admission, eight ancestors, and that he should keep out of trade; the other society, of the house of Frauenstein, consisted mostly of newly-ennobled merchants "of distinction." In Augsburg, the old patricians were more indulgent to merchants: he who had married the child of a patrician family, could be received into the noble society. The remaining commercial cities of note, Prague and Breslau, were most amply supplied with newly ennobled merchants. There was bitter complaint that, under the Emperor Leopold, even a chimney-sweeper, whose trade was then in particularly low esteem, could for a little money procure nobility, and that frequently tradesmen, with patents of nobility in their pockets, might be found packing up herrings for their customers in old paper. After the Thirty Years' War, officers also sought for patents of nobility, and they were often granted to them for their services, as also to the higher officials and members of the city administration in the larger cities. It was through families who had taken part in the literary and poetical culture of the time, that patents of nobility in this and the following century entered into our literary class. Many poets of the Silesian school, nay, Leibnitz, Wolf, and Haller, were placed among the privileged of their time by patents of nobility, which they themselves or their fathers had acquired.
