Ornaments, jewellery, personal equipment and weapons in graves can be defined as relicts of ancient costumes and weapon assemblages which are connected to the social identities of the buried persons. At several late Bronze Age and early Iron Age sites in the north Caucasus (Koban culture) large numbers of richly furnished graves allow the reconstruction of specific costume and armour groups. These can be related to factors which structured these communities into a ranked society. This article is based on the investigation of two cemeteries in Chechenia (north-eastern Caucasus) which demonstrate the change in social differentiation during the developed Iron Age. The article also includes a general discussion about the concepts of costumes and their potential for reconstructing social identities.
