This chapter considers interculturality through majority and minority power relations in the European contexts of ethnic nationalism, migration and diaspora from a comparative historical perspective. In the phenomenological framework of thinking, interculturality goes beyond a mere ‘tolerance of the other’. It requires engagement by employing a comparative gaze. The chapter starts with three propositions: first, international relations both influence and are influenced by the dominant worldviews and scholarly endeavours such as social Darwinism; second, the condition of international relations and the psycho-cultural norms of Volksgemeinschaft based on ‘blood and soil’ (Blut und Boden) have set boundaries and created biases in international and intercultural relations; and third, there is a conflation of ‘nation’ and ‘state’ as if all states are territorialised nations with sovereignty. Within this framing, the chapter examines the Jewish and East Asian cases and illustrates the institutionalisation of strangerhood in the context of ethnic nationalism and interculturality in Europe. The conclusion suggests the need for rethinking the dynamics of majority-minority power relations.
