This article analyses the impact of a recent revival of nationalist narratives in The Netherlands on the issue of European identity. In the past decade, a sensitive and very salient debate has risen around the controversial figure of Zwarte Piet, part of a popular national festival called Sinterklaas. The article explains the nature of this tradition and elaborates on the development of the public debate on the topic. By analysing the defensive reaction towards criticism from Dutch action groups, the European Parliament and the United Nations, the article intends to expose an emphasis on nationalist arguments and invented traditions. It is often argued that the debate has already led to an increase in polarization in the country itself, but the article shows that it could also potentially function as a threat to European identity.
