Europe has seen a national populist turn in recent years, a movement away from liberal elites and the rise of 'post-truth' politics. While populist parties may have passed the high point of their success, their politics has had a considerable impact on the mainstream, drawing traditional parties in populist directions. In this article, I consider the consequences of this for those of a liberal persuasion, who value openness and diversity and who are suspicious of those bringing simple solutions to complex problems. I reflect on the findings of a series of comparative education policy and pedagogy studies that I have conducted with colleagues in northern Europe over the past ten years, and in their light, make a number of suggestions for how education can defend liberalism while taking the concerns of national populists seriously.
