to by their titles. For example, Karl Schwarzenberg will occasionally still be referred to as Fürst zu Schwarzenberg (Prince zu Schwarzenberg) in the media; he holds Czech and Swiss citizenship, not Austrian. Unlike the nobility in Bohemia (Czechoslovakia), Poland, Russia, or the former Prussian territories, the Austrian nobility never had its lands and riches confiscated in Austria (except the Imperial House of Habsburg, which had its properties legally confiscated by the Austrian republican government in 1919). 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. However, there was no measure by the government specifically to target nobility and take away their possessions. Still, the nobility today are sometimes nonetheless treated slightly differently from other citizens. 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. The social events of nobles are still covered extensively in tabloids. Besides, the law is often broken on occasions when members of the nobility are addressed at various events: at the annual birthday celebration of Emperor Franz Joseph in Bad Ischl, for example, members of the former Imperial House of Habsburg are addressed as "Imperial and Royal Highness". Apart from the prohibition of their titles, some former nobles still make up some of the richest families in Austria, such as the Esterházy, Mayr-Melnhof and Mautner-Markhof. 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. It was estimated that there were about 20,000 Austrian nobles in 2005. That year, an association was founded, the Vereinigung der Edelleute in Österreich (Association of Austrian Nobles, or V.E.Ö.), which sees itself as the successor of the Vereinigung katholischer Edelleute in Österreich (Catholic Association of Austrian Nobles, or V.E.Ö.), founded in 1922 but banned under the Nazis in 1938. Until recently, all of the various attempts at revival were blocked by Austrian authorities. Categories of nobility Austria's nobility was divided into three categories: the mediatized nobility (standesherrlicht), the higher nobility (hoher Adel), and the lower nobility (niederer Adel): Non-ruling members of the
