Not long ago, conceptual history was an approach restricted to German-speaking academic circles and to very few scholars worldwide. This situation has markedly changed in the last two decades, primarily of the appearance of research projects for studying concepts in historical perspective in other European countries — such as Finland, Netherlands, Denmark, Sweden, Italy, France, and Spain — and because of Melvin Richter’s endeavor in promoting an encounter between German Begriffsgeschichte and English speaking approaches for the historical study of political languages, discourses, and rhetoric. The History of Political and Social Concepts Group (HPSCG) is among the most significant results of these developments.
