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.
Vlachs in the history of Croatia
Socioculturally, there were two main ethnic divisions in the Croatian Military Frontier, those of the "native" "Croats" and "immigrant" "Vlachs". The Croats were Catholics, Habsburg subjects, made up of an agrarian population concentrated around frontier towns, of nuclear families, and linguistically predominantly Chakavian-speaking (or Chakavian-based speech). The Vlachs were holders of patriarchal-pastoral culture of the Dinaric, refugees from Ottoman and Venetian territories, of extended families, and linguistically Neo-Shtokavian-speaking.
