Sirmium - A settlement in Pannonia
Sirmium was an ancient city founded in the 3rd century BC by Illyrians or Celts, and conquered by the Romans in the 1st century B.C.

It was the economic capital of Roman Pannonia and the birth-place of the emperors Probus, Maximianus, Gratian and Aurelian.

During the tetrarchy it was the capital of the emperor Galerius, one of the four capital cities of the Empire (the other three being Trier, Mediolanum, and Nicomedia).
