Bosnian, Croatian, Montenegrin, and Serbian (otherwise known as one language: Serbo-Croatian) are natively spoken by about 13 million people combined, primarily in Serbia, Montenegro, Bosnia and Herzegovina, and among Serbian and Montenegrin communities worldwide. They are integral to the cultural identities of their respective countries, known for their literature, traditional music, and shared history in the former Yugoslavia.
