This paper suggests that the study of the modernisation of European political cultures in the eighteenth century would greatly benefit from a comparative conceptual historical approach. is approach would effect the reconstruction of a variety of meanings attached to chosen political concepts in different national contexts through the side-by-side analysis of primary sources originating from each case according to the methodology of both historical semantics and pragmatics. A promising research topic is the continuity and change in the conceptualisation of national community, national identity, popular sovereignty and democracy in various European political cultures. e conceptual analyses of late eighteenth-century political sermons from five northwestern European countries, conducted by the author, for example, reveal that conceptual changes related to the rise of nationalism took place even within public religion, allowing it to adapt itself to the age of nationalism. Further analysis of the secular debates taking place in representative bodies and public discourse in late eighteenth-century Britain, the Dutch Republic and Sweden elucidates the gradual development of the notion that all political power is ultimately derived from the people and that such a system constituted a "democracy" in a positive sense within different parliamentary traditions and perhaps even before the French Revolution.
