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.
Dialects of Serbo-Croatian
Kajkavian literary language gradually fell into disuse since Croatian National Revival, ca. 1830–1850, when leaders of the Croatian National Unification Movement (the majority of them being Kajkavian native speakers themselves) adopted the most widespread and developed Serbo-Croatian Shtokavian literary language as the basis for the Croatian standard language. However, after a period of lethargy, the 20th century has witnessed new flourishing of literature in Kajkavian dialect – this time as Croatian dialectal poetry, main authors being Antun Gustav Matoš, Miroslav Krleža, Ivan Goran Kovačić, Dragutin Domjanić, Nikola Pavić etc. Nowadays, Kajkavian lexical treasure is being published by the Croatian Academy of Sciences and Arts in "Rječnik hrvatskoga kajkavskoga književnoga jezika"/"Dictionary of the Croatian Kajkavian Literary Language", 8 volumes (1999).
