In Croatia, all ethnic groups speak Croatian regional dialects of Serbo-Croatian. Since the collapse of the former Yugoslavia in 1991, the Croatian government has sought to differentiate a separate Croatian language -officially Croato-Serb or simply Croatian from Serbian or Bosnian variants of Serbo-Croatian spoken in the FRY and Bosnia. Croatia has insisted on the exclusive use of the Latin alphabet, rejecting the Cyrillic alphabet used in the FRY and parts of Bosnia.
