The role of Pannonian soldiers in the guards is traceable from the 2nd century while their number and significance had grown considerably both in the units of praetoriani and equites singulares from the rule of Septimius Severus. Inscriptional sources mention that from time to time their families, wives and kin moved to Rome with the guardsmen. On their gravestone reliefs, one can find themes both from their homelands, traditions and from new Roman erudition. The decades spent serving the Emperor in Rome could mean social advancement, gaining fortune and recognition while the best ones could become military officers. After retiring from service, they could play an important role in the life of the province and in the Romanization of Pannonia as well.
