In this article, we propose an alternative Foucauldian reading of Martin Luther’s thought and early Lutheranism. Michel Foucault did not mention the Reformation often, although he saw it as an amplification of pastoral power and the governing of people’s everyday lives. We aim to fill the gap in his analysis by outlining the disciplinary and biopolitical aspects in Luther and early Lutheranism. Therefore, we also contribute to the ongoing debate regarding the birth of biopolitics, which, we argue, predates Foucault’s periodisation. Our approach to tackling these questions is three-pronged. First, we establish the context by highlighting a few Reformation-era examples of the conceptual opposite of biopower, namely, sovereign power. Second, we scrutinise the disciplinary aspects of early Lutheranism, underscoring the fact that disciplinary institutions appear to subject people to new models of behaviour. Third, we describe the biopolitical undercurrents in Luther’s thought and its early reception. We argue that the reformer’s views on issues such as marriage and poor relief appear to carry a biopolitical significance before the alleged birth of biopolitics.
