Southern Transdanubia, i.e. Baranya, Somogy, Tolna and Zala Counties used to be a densely populated area, strewn by small villages, the greater part of which lost its population during the Turkish occupation. Since the 16th century Serbians, Catholic Serbians, Croatians and Hungarians have coexisted in this region. The tradition of busójárás, having been a famous carnival custom for a long time in Mohács, is of Croatian origin.
