During the history, the region of Baranya was part of the Roman Empire, the Hunnic Empire, the Kingdom of the Ostrogoths, the Kingdom of the Lombards, the Avar Kingdom, the Frankish Empire, the Balaton Principality, the Bulgarian Empire, the Kingdom of Hungary, the Ottoman Empire, the Habsburg Monarchy, the Austrian Empire and the Austria-Hungary.
