Although Volk may be considered as a central concept in the work of Carl Schmitt, and one to which the German jurist dedicated a sizable amount of writing, a remarkably limited number of publications have so far provided an analytical study of how Schmitt conceptualised Volk, particularly in English-language secondary literature. This article intends to address this gap by systematically reviewing how the concept of Volk appears in the Schmitt's theoretical effort, with a particular focus on his publications from the late 1920s to 1945, and how it relates to his main legal-theoretical and political claims, both in his constitutional doctrine (Staatsrechtslehre) as well as in international law. It sketches some interpretive pathways to locate Volk in a broader historical and theoretical context, and it offers a conceptualisation of the relation between Schmitt and existentialist nationalism.
