History
People have lived here since about 5000 BC, and Sirmium was already an old settlement when the Romans took it in the 1st century BC. It became a colony of Roman citizens and a military base on the Pannonian frontier, from which Trajan, Marcus Aurelius and Claudius II prepared their campaigns; Marcus Aurelius probably wrote part of his Meditations here. In 103 it became the capital of Pannonia Inferior, and in 293, under the tetrarchy, one of the four capitals of the Roman Empire, with Trier, Milan and Nicomedia. Ten emperors were born in or near the city, among them Aurelian, Probus and Constantius II, and Theodosius I became emperor here. It was also an early Christian centre and the seat of a bishop.
Huns took the city in 441, and after Goths, Gepids and Byzantines the Avars destroyed it in 582. A medieval town grew on the ruins as Civitas Sancti Demetrii, after the martyred Saint Demetrius, from which comes Mitrovica. Under the Ottomans from 1521 it was the largest settlement of Syrmia, a mainly Muslim town with 17 mosques by 1573. The Habsburgs took it in 1717, and Serbian, Croatian and German settlers replaced the fleeing Muslims.
In the Second World War the town was attached to the Independent State of Croatia, and one of its largest camps operated here; up to 10,000 Serbs, Jews and antifascists were killed. In 1991–92, during the Yugoslav wars, Croatian prisoners of war were held in a camp at the town's prison, where many prisoners were tortured and abused. Since 1944 Sremska Mitrovica has been part of Vojvodina, and of an independent Serbia since 2006.
