Much has been written in recent years about Identities, understood as social, nested or constructing identities; or 'Ethnic Identity', presented as a strategy of distinction and/or identification, as a multidimensional or endogenous ethnicity, or also interpreted as a social construction, social network, negotiated or group identity; and concerning the 'Archaeology of the Identity', including the explicit relation between mortuary practices and Social Identities in a 'multi-ethnic' perspective or as a 'constructed strategy of shifting identities'. This book is not 'another brick in the wall', but a contribution to 'break the wall' between different disciplines in an interdisciplinary and multidisciplinary framework. We present in this volume fifteen papers focused on theoretical and interpretative proposals from the textual, archaeological and bioarchaeological record, as well as a series of 'case studies' on certain European areas essentially throughout the analysis of the funeral world in the Late Antiquity and the Early Middle Ages.
