Populism has been one of the most used and theorised concepts in political scholarship for at least two decades. In political science, the conceptualisation of the term has amounted to an insightful, though somewhat repetitive debate between and within a variety of ‘schools’ that each postulate their own understanding of populism: as a (thin) political ideology, as a political logic or as a political style – to name but three predominant ones. By contrast, historians have only engaged with this pertinent debate to a limited extent. Rather than adopting an a priori conceptualisation or operationalisation of populism, a significant amount of historical scholarship either takes its cues from historical actors who are self-defined populists, or tends to loosely and intuitively adopt the term without much conceptual or theoretical motivation. This discrepancy between social scientific and historical populism research begs for a meaningful interdisciplinary conversation that sees populism as a modern political experience and faculty beyond the contemporary populist moment of the 21st century. This chapter analyses populism at the intersection of historical inquiry and political science-induced conceptualisations by engaging with the historical case of the Dutch Boerenpartij (Farmers’ Party) in the post-war decades.
