Human habitation in the Osijek area dates to the Neolithic period [1]. During the second half of the 4th century BC, the settlement was attacked and subsequently captured by the Celtic Scordisci, who established a permanent presence there [1]. Following the Roman conquest of Pannonia, the settlement—then known as Mursa—was garrisoned by the Roman Seventh Legion [1]. The legion administered the area from a military castrum and built a bridge across the Drava River [1].
