Societies within Europe, and beyond, are characterised by intersectionalities of ‘race’/ethnicity, gender, sexuality, faith and other markers of diversity. Added to this are increasingly fluid and diverse communities of individuals within and across national boundaries, whose loyalty and sense of belongingness may be multiple. Within this complex environment, ‘doing citizenship’, for both state and non-state actors and institutions, creates both challenges and opportunities. This international, multi-disciplinary conference is sponsored by the European Union and is organised by the School of Psychology, Criminology and Sociology at Kingston University London and the Centre for the European Union in South West Russia. It aims to examine the complexities to doing citizenship with respect to the three key themes of: Engaging with Diversity, Security, Negotiating European Citizenship.
