Demetrius Zvonimir

Demetrius Zvonimir was a King of Croatia and Dalmatia from 1075 or 1076 until his death in 1089. Prior to that, he served as Ban of Croatia (1064/1070–1074) He inherited the Croatian state at its height and ruled from the city of Knin. Medieval legends allege his assassination, but his death and succession are subjects of controversy in historiography. His reign was followed by a period of anarchy, which ended with the ascension of the Hungarian Árpád dynasty and the creation of a union with Hungary. His exact origin and background are uncertain. It is believed that he was a member of the native Trpimirović dynasty, and some historians have proposed that he is a descendant of Svetoslav Suronja's son Stjepan Svetoslavić. However, there's lack of historical evidence that he ever held the title of Ban of Slavonia, or ruled over the region. The term "Slavonia" (Latin: Sclavonia) at the time referred to both modern day Slavonia and North-West Croatia.
