With the same date, the "Habsburgergesetz" of 1919 ("Habsburg Law"), which legally dethroned, exiled and confiscated the properties of the Imperial House of Habsburg, the "Adelsaufhebungsgesetz" (Arbitration Act) of 3 April 1919 ("Law on the Abolition of Nobility") abolished nobility as well as all noble privileges, titles and names in Austria. In other monarchies of Europe, Austrian noble families may use their noble titles as well as nobiliary particles such as "von" and "zu" in their names and they still retain noble status there. For example, the name of the heir to the Austro-Hungarian throne became in Austria simply Karl Habsburg-Lothringen instead of Karl von Habsburg; in Belgium, however, he is known as Archduke Karl of Austria.
