Black Sea-Carpathian region who settled in Bohemia, Moravia and parts of present-day Austria in the 6th century AD. Other ethnic groups include Germans, Romani people, Poles, and Hungarians. Historical minorities like Germans and Poles are declining due to assimilation. There is also a growing community from Vietnam. Other ethnic communities like Greeks, Turks, Italians, and Yugoslavs are found in Prague. Since the dissolution of Czechoslovakia, Slovaks living in the Czech Republic have comprised roughly 3% of the population. There are different groups of national and ethnic minorities in the Czech Republic. The so-called "old minorities" live mostly in specific areas (e.g. Poles in the Zaolzie region, Germans in the Hultschiner region) while the "new minorities" are scattered among the majority population (generally in the larger towns). While some of the minorities have the whole social structure of Czech society (Poles, Slovaks, Greeks and Ukrainians), other represent only some of the social groups (i.e. Russian newcomers of middle class, and Romani people who generally represent the underclass). 1880–1910 After World War I 1 In 2011 a large part of the population did not claim any ethnicity, before the census it was widely mediatized that the question is not mandatory. The vast majority of those who did so are presumed to be ethnic Czechs, number of whom dropped by roughly the same amount that the number of undeclared people rose, circa 2.5 million. The legal position of the minorities is defined foremost in the Act No. 273/2001 Coll. (The Rights of the Minorities Act) which implements the Charter of Fundamental Rights and Basic Freedoms, Framework Convention for the Protection of National Minorities and Recommendation of the Council of Europe No. 1201. There is a number of other enactments which to lesser extent deal with the minorities. A special situation applies in the case of Moravians and Silesians, who are frequently allocated within the group of Czechs when it comes to the statistical data. Officially recognized minorities Minorities, which "traditionally and on a long term basis live within the territory of the Czech Republic" enjoy some privileges. As of 2022 there are 14 such officially recognized minorities, which are (alphabetically): Belarusians, Bulgarians, Croatians, Germans, Greeks, Hungarians, Poles, Romani people, Russians, Rusyns, Serbians, Slovaks, Ukrainians and Vietnamese. Citizens belonging to the officially recognized minorities enjoy the right to "use their language in communication with authorities and in courts of law". Article 25 of the
