20th and 21st centuries In many European countries, the nobility has lost its political power as an independent class due to the development of republics, constitutional monarchies, socialist or communist systems. However, due to its continuing social prestige, it is still represented more often than average in representative leadership positions (more than in actual positions of power). Until the 20th century, it represented a relatively closed social class, and today it often still represents at least a style-determining social milieu (comparable to the various layers of the bourgeoisie) with its own lifestyles, ways of behaving and differentiated class ethos. The associations of the nobility, such as the umbrella organization Cilane and the individual aristocratic associations in European countries, are used by some of the nobility as interest groups. The situation of the nobility in the various European countries is very heterogeneous today – a consequence of the very different historical processes in the countries: In some countries in Western and Northern Europe, the nobility has experienced continuity, despite all the changes and the gradual sharing and giving up of its political power (e.g. Great Britain and Northern Ireland, the Netherlands, Belgium, Luxembourg, Norway, Sweden, Denmark, Liechtenstein, Monaco, Spain). In these countries, monarch families are the representatives at the head of the state, although in some cases without or with very limited power (see, for example, the constitutional bodies of the United Kingdom). Nobles in Great Britain and Northern Ireland sit in the House of Lords, advancement to the nobility through ennoblement is still possible in some countries (e.g. Great Britain and Northern Ireland, Belgium, Spain), and they are still organized in associations (e.g. the Swedish Riddarhuset); nobles naturally form part of the elite there. In other European countries, however, a clear break has taken place. Among them are countries that became republics, e.g. France, Germany (1918/1919) and Italy. In these countries, the nobility mostly lost all of its political power in one fell swoop, but in some cases still had a certain social weight, while at the same time increasingly opening up to the upper and educated middle classes in terms of marriages. In some countries, the nobility was completely abolished, as in Austria (Nobility Abolition Act 1919). Nobles became normal citizens and were prohibited from using a noble title. However, there was no interference with property rights, except for the ruling family (Habsburg Laws). Finally, in some other countries, especially in the east, the nobility experienced an even sharper break with the establishment of socialist or communist dictatorships (Soviet Union, SBZ/GDR, Poland, etc.). Here, the nobility was in some cases completely stripped of its property, expelled, interned or shot. In Germany, the observance of the law of nobility, which goes back to the principles of Salic law, still plays a role today, especially in the regularly published volume series of the Genealogical Handbook of the Nobility and in the monthly magazine Deutsches Adelsblatt, under the supervision of a "German Nobility Law Committee", since the design options of today's name law (adoptions, passing on the name by women who have married out, adopted husbands, illegitimate children, etc.) produce numerous name bearers who do not belong to the "historical nobility" ("pseudo-nobility"). In Austria, on the other hand, such a "flood of titles" was prevented by the deletion of all titles in 1919; here, the only thing that counts is knowing which families and which of the associated name bearers belong or belonged to the nobility.
