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.
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).
