One particularity of the social make-up of Dacia is that, unlike other provinces in the area, it provides significant evidence for the establishment of larger groups of immigrants as a result of Roman conquest. These ethnic communities bring with them their own organisation and hierarchy, customs and material culture. Through types and decoration of monuments made by their own craftsmen, individuals of these groups communicate among other things, not just their ethnic, but also their religious and social identity.
A Hadrianic municipium which later becomes a colonia under Marcus Aurelius, Roman Napoca experiences generational developments in the social behaviour of its inhabitants in parallel with its political, demographic and economic development. By combining epigraphic and archaeological evidence, the paper will explore the nature and mechanisms behind the evolution in social behaviour and identity display of the inhabitants from the beginnings of the town, when diasporas of Norico-Pannonians and north Italians were living there alongside indigenous Dacians, to its second generation shift in emphasis from ethnic to wealth-related identity markers, while new ethnic presences from Asia Minor and possibly Moesia are making an appearance.
