This paper examines standardization from a double perspective: material and ideological. By focusing on the transformation of urban features in Italian cities between the third and first centuries BCE, it analyzes the growth of civic institutions and social life within these communities. In particular, it offers various case studies on how the homologation and standardization of many urban spaces and architectural forms relate to the evolution of political institutions and social relationships, particularly concerning the role of élites at the interface between the local dimension and the new system of Roman hegemony. Civic culture, memory, and practices, together with how they are reflected in spaces and monuments, offer unique insights into the complex phase of urban and civic growth of Italian communities in the late Hellenistic centuries.
