Any noble living in the Habsburg-ruled lands, and who owed allegiance to the dynasty and therefore to the emperor, was also considered part of the Austrian aristocracy.
Besides the Holy Roman Emperor (an office which was almost uninterruptedly held by the Archduke (of the House of Habsburg) from 1438 to 1806), only a few territorial rulers within the Empire had this right.
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.
A few very wealthy Jewish families were ennobled after the Toleranzedikt vom 1782 ("1782 Edict of Tolerance") decreed by Emperor Joseph II.
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.

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.
The elevation into the nobility of wealthy Jews also started the process of assimilation of Jewish families into the Austrian upper class.
Also, members of noble families often hold multiple citizenships, as was the case for Otto von Habsburg (eldest son of the last Emperor of Austria-Hungary and father of Karl Habsburg-Lothringen), who was also a citizen of Germany.
Members of the lower nobility especially (such as civil servants) found this radical step of abolition degrading and humiliating, since working towards and finally earning a noble title was a way for them and their families to rise within society.
Following the Anschluss to Nazi Germany (1938–1945), this law remained on the books, although it was not enforced, allowing Austrian nobles to use titles freely again.
Social measures were introduced by the republican government in order to create more equality amongst the citizens and finance public projects, which put a strain on the traditional land-holding gentry and aristocracy, resulting in the forced sale of many palaces and lands due to the expense of their upkeep.
Austrian nobility still plays a large part in movies made after World War II (for example, Sissi and The Sound of Music), and is still featured regularly in the media and literature.
Many members of the Austrian nobility today work in the traditional fields of diplomacy, politics, have business and financial interests, or are philanthropists or socialites.
The rank of Edler carried no official style, but "Gnädiger Herr" or "Gnädige Frau" were common forms of address.
This title belonged to the patricians of the free city of Werl, in Germany, who had the hereditary (erb-) right to exploit the nearby salt mines (salz).
