Sporadic epigraphic evidence in grave site excavations, particularly in Brigetio (Szőny), Aquincum (Óbuda), Intercisa (Dunaújváros), Triccinae (Sárvár), Savaria (Szombathely), Sopianae (Pécs), and Osijek in Croatia, attest to the presence of Jews after the 2nd and 3rd centuries where Roman garrisons were established, There was a sufficient number of Jews in Pannonia to form communities and build a synagogue. Jewish troops were among the Syrian soldiers transferred there, and replenished from the Middle East, after 175 C.E. Jews and especially Syrians came from Antioch, Tarsus and Cappadocia. Others came from Italy and the Hellenized parts of the Roman empire. The excavations suggest they first lived in isolated enclaves attached to Roman legion camps, and intermarried among other similar oriental families within the military orders of the region.Raphael Patai states that later Roman writers remarked that they differed little in either customs, manner of writing, or names from the people among whom they dwelt; and it was especially difficult to differentiate Jews from the Syrians. After Pannonia was ceded to the Huns in 433, the garrison populations were withdrawn to Italy, and only a few, enigmatic traces remain of a possible Jewish presence in the area some centuries later.
