Croatian language
Standard Croatian is the official language of the Republic of Croatia and, along with Standard Bosnian and Standard Serbian, one of three official languages of Bosnia and Herzegovina. It is also official in the regions of Burgenland (Austria), Molise (Italy) and Vojvodina (Serbia). Additionally, it has co-official status alongside Romanian in the communes of Carașova and Lupac, Romania. In these localities, Croats or Krashovani make up the majority of the population, and education, signage and access to public administration and the justice system are provided in Croatian, alongside Romanian.
Serbian language in Croatia
The Law on Use of Languages and Scripts of National Minorities provides for a mandatory co-official use of minority languages in municipalities of Croatia with at least one third of members of ethnic minoritiy. Municipalities Dvor, Gvozd, Jagodnjak, Šodolovci, Borovo, Trpinja, Markušica, Negoslavci, Biskupija, Ervenik, Kistanje, Gračac, Udbina, Vrbovsko, Donji Kukuruzari, Erdut and Vukovar, according to the provisions of law, are obliged to grant equal co-official use of Serbian language and Serbian Cyrillic alphabet. Law enforcement is facing great resistance in the part of the majority population, most notably in the case of Vukovar where it led to 2013 Anti-Cyrillic protests in Croatia.
