The primary difference among the largest ethnic groups is religious, the Serbs being traditionally Orthodox Christians and the Croats Roman Catholics. The Bosnian Muslims, descendants of Slavs who converted to Islam in the 15th and 16th centuries, are generally Sunni Muslims (see Sunnites). Bosnia also has a small number of Jews. The people of Bosnia speak the Bosnian dialect of the Serbo-Croatian language. However, according to the Bosnian government, the country officially has three languages: Serbian, “Bosnian” (the language associated with the Muslims), and Croatian. In writing, the Serbs use the Cyrillic alphabet, while the Muslims and Croats use the Latin alphabet.
