Dialects of Serbo-Croatian
Kajkavian is spoken in North Croatia, including the capital Zagreb, as well as in a few enclaves in Austria, Hungary, and Romania. Though its speakers are ethnic Croats and Kajkavian is thus generally considered a dialect of Serbo-Croatian, it is closer to neighboring Slovene than it is to Chakavian or Shtokavian. The Kajkavian area of Croatia is bordered on the northwest by Slovene language territory. It is bordered on the east and southeast by Shtokavian dialects roughly along a line that was the former division between Civil Croatia and the Habsburg Military Frontier; in southwest along Kupa and Dobra rivers, it persisted in ancient (medieval) contact with Chakavian dialects.
Minority languages of Croatia
In the first years after introduction of new Constitutional Act on the Rights of National Minorities some local governments resisted implementation of its legal obligations. In 2005 Ombudsman report, municipalities of Vojnić, Krnjak, Gvozd, Donji Kukuruzari, Dvor and Korenica were mentioned as those that do not allow the official use of the Serbian language, although the national minority in these places meets the threshold provided for in the Constitutional Act. The report pointed out that Serbian minority in Vukovar can not use Serbian language although minority constituted less than one percent less population than it was prescribed by law. After 2011 Croatian census Serbs of Vukovar meet the required proportion of population for co-official introduction of Serbian language but it led to Anti-Cyrillic protests in Croatia. In April 2015 United Nations Human Rights Committee urged Croatia to ensure the right of minorities to use their language and alphabet. Committee report stated that particularly concerns the use of Serbian Cyrillic in the town of Vukovar and municipalities concerned. The Constitutional Court of Croatia upheld the legislation on the use of minority languages. It relied on a newly developed concept of national identity.
