This Special Issue of Nordicom Review discusses interactive practices of articulating and communicating uncivility in the context of recent wider anti- and post-democratic change. We consider that change as a cross-national phenomenon that has been taking place in the Nordic countries, Europe, and indeed elsewhere since the late 1990s and early 2000s, and one that has significantly accelerated with the global rise of the “anxious politics” (Albertson & Gadarian, 2015) of right-wing populism and the far-right (Moffitt, 2016; Mudde, 2019) in recent decades. While our collection joins an ongoing and growing body of research on both un- and incivility – which we describe and to some extent disentangle conceptually in detail below – it carries a few pronounced aims which characterise its contribution to the wider research on mediated and political communication in the context of a crisis of liberal democracy and the rise of nativism and far-right populism.
