This chapter analyses the conceptual clusters that have been formed in the debates over parliamentary government in Denmark, Finland and Sweden. The aim is to bring forth a transnational view by paying attention to the ways in which the parliamentary life of other countries was referred to and commented on in the examined countries. Our discussion extends from the age of post-revolutionary constitution making in the early nineteenth century through the debates over the introduction of the principle of parliamentarism to the breakthrough of parliamentary democracy in the early twentieth century.
