Demographics of Croatia
Croatian replaced Latin as the official language of the Croatian government in 1847. The Croatian lect is generally viewed as one of the three standard varieties of the Shtokavian dialect of Serbo-Croatian, a South Slavic language. Croatian is written using the Latin alphabet and there are three major dialects spoken on the territory of Croatia, with the Shtokavian idiom used as the literary standard. The Chakavian and Kajkavian dialects are distinguished by their lexicon, phonology, and syntax.
Serbian Cyrillic alphabet
Cyrillic is in official use in Serbia, Montenegro and Bosnia and Herzegovina. Although the Bosnian language "officially accept[s] both alphabets", the Latin script is almost always used in the Federation of Bosnia and Herzegovina, whereas Cyrillic is in everyday use in Republika Srpska (and is used only by the Serbs in the country). The Serbian language in Croatia is officially recognized as a minority language, however, the use of Cyrillic in bilingual signs has sparked protests and vandalism.
