Kajkavian
The major cities in northern Croatia are located in what was historically a Kajkavian-speaking area, mainly Zagreb, Koprivnica, Krapina, Križevci, Varaždin, Čakovec. The typical archaic Kajkavian is today spoken mainly in Hrvatsko Zagorje hills and Međimurje plain, and in adjacent areas of northwestern Croatia where immigrants and the Štokavian standard had much less influence. The most peculiar Kajkavian dialect "(Baegnunski)" is spoken in Bednja in northernmost Croatia. Many of northern Croatian urban areas today are partly Štokavianized due to the influence of the standard language and immigration of Štokavian speakers.
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).
