In Central Europe, the role of religion in the creation of modern states has had many guises. In some predominantly Catholic countries, religious minorities have been an important source for national movements that sought emancipation from dominant political rule, which was often connected with the dominant (Catholic) religion. The article is focused on the case of Slovakia, where Lutherans, in spite of making up only a small proportion of the Slovak population, have been one of the two fundamental sources of the national movement for the last two centuries. It shows how the contemporary character of the state, society, and national identity and its relation to religion is influenced by the bi-confessionalism (dualism) of the Slovak national movement that was initiated by Slovak Lutherans in the eighteenth century. Although the Lutheran religious minority has been disappearing since 1990, the article shows how its heritage is still present in the character of contemporary institutions of national tradition and identity.
