Increasing migration worldwide and the cultural diversity generated as a consequence of international migration has facilitated the unions of people from different countries, religions, races, and ethnicities. Such unions are often celebrated as a sign of integration; however, at the same time as they challenge people’s idea of us and them, intermarriages in fact still remain controversial, and even to some extent, taboo in many societies. Research and theorizing on intermarriage is conducted predominantly in the English- speaking North American and British contexts. This special issue includes empirical studies from not only the English-speaking countries such as the U.S., Canada, and the UK, but also from Japan, Sweden, Belgium, France, and Spain and demonstrate the increasingly diverse directions taken in the study of intermarriage in regards to the patterns, experiences, and social implications of intermarriages. Moreover, the articles address the assumed link between intermarriage and ‘‘integration.’’
