of Austria from 1804 onwards, continued to elevate individuals to nobility until the end of the monarchy in 1918. Some of the noble families even obtained the right to be seated in the Herrenhaus (House of Lords), the upper house of the Reichsrat (Imperial Council). Nobles from previously sovereign states such as those in northern Italy (Venice, Mantua, Milan) were also recognized by the authorities and were allowed to keep their titles and rights. Burgenland On the former status of nobility in Burgenland, which was part of the Kingdom of Hungary until 1921, see Hungarian nobility. Jewish nobles A few very wealthy Jewish families were ennobled after the Toleranzedikt vom 1782 ("1782 Edict of Tolerance") decreed by Emperor Joseph II. Under this Edict, very wealthy Jewish bankers, and later entrepreneurs and industrialists—some of them court Jews—could also be ennobled for their services. Jews had been ennobled mostly, as was common with all newly ennobled families, with lesser noble ranks, but also with peerages such as Freiherr (Baron). The few Jewish families elevated into the nobility were not required to forswear their faith, but some of these families converted to Christianity in order to become more accepted. Although elevation into the nobility meant recognition for civic contributions and services, and entailed a rise in social status, it did not alter the fact that Jews were, for the most part, still only "tolerated" at best. Jews could not freely choose the place and duration of their stay and had to regularly ask for permission from the authorities. This placed a huge burden on Jewish families; if the head of the family died, all his relatives had to leave the city. The right to purchase real estate was forbidden to Jews, even if they belonged to the nobility. This regulation stayed in place until 1860, when it was abolished by Emperor Franz Joseph I and Jewish citizens were given equal rights. When the banker and protector of arts Raymund Karl Wetzler von Plankenstern was created a Reichsfreiherr (Baron of the Empire) by Empress Maria Theresia, he converted to Catholicism while still young. His mansion in Vienna was a center of the fine arts and he was a close friend of Mozart, as his son Alexander was of Ludwig van Beethoven. Despite these difficulties, by 1821 there were at least eleven ennobled Jewish families living in Vienna alone: the Rothschild, Arnstein, Eskeles, Gomperz, Kuffner,
