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.
Vlachs in the history of Croatia
According to Stjepan Pavičić (1931), the Romance Vlachs or Morlachs of the Dinara and Velebit lost their Romance language by the 14th or 15th century, or were at least bilingual at that time. The so-called Istro-Romanians, called by themselves "Rumeri" or "Vlasi", continued to speak their language on the island of Krk (extinct in the 20th century; recorded Pater Noster) and villages around the Čepić lake in Istria, while other communities in the mountains (Ćićarija) above the lake preserved the Shtokavian-Chakavian dialect with Ikavian accent from the southern Velebit and area of Zadar. The documents about Vlachs from Cetina county indicate Chakavian dialect with Ikavian accent.
