Can it be argued that there exists a concept of Nordic citizenship, founded on inter-Nordic cooperation and its relationship with EU law and EEA law? Researchers from all five Nordic States (Denmark, Finland, Iceland, Norway and Sweden) explore the tensions, gaps, and overlaps arising from the interplay of EU citizenship, EEA law, and the Nordic initiatives that aim to facilitate cross-border mobility of persons in the region. The analysis takes a dual approach. Firstly, it tracks the legal development of nationality law in Nordic states. Secondly, it sets out the rights of residence and access to social rights that follow from the three different regimes. It asks if the Nordic States, through their regional cooperation, are 'going beyond' EU free movement law, making naturalisation to a citizenship in a Nordic state particularly attractive. This important new work gives a unique perspective on EU citizenship and free movement law.
