Current scholarship pays little attention to late Etruscan social structures (post-400 BCE), when Etruscans are assumed to have increasingly modelled themselves on Rome. Existing scholarship often argues that pre-400 BCE, Etruscan society was dominated by kinship structures, while after 400 BCE, the Etruscan republics lost such structures and developed into Rome-like city-states. By making use of the so far underutilised wealth of later Etruscan epigraphic evidence as well as residential and funerary archaeology, I aim to show that, contrary to existing views, kinship structures played a decisive role in post-400 BCE Etruscan societies, and thus in the process of Etruscan city-state development and integration into the wider Italian community, while the role of Rome as a model was decidedly less clear-cut and influential than often supposed. Residential and funerary aspects coincide in the concept of the ‘house society’ (Lévi-Strauss), focusing on physical places where the family name and patrimony were perpetuated through discursive practice, manipulating (family) identity and views of society. Innovative aspects of my project are the systematic gathering and analysis of late residential evidence as well as the structural analysis of family composition and a diachronic view of the various social groups visible in funerary culture via Social Network Analysis.
