Pathways to Path-Dependence, 1918–90
During 1918–90 ideological, anti-system communist and fascist parties emerged. Anti-system obstruction and the response to it from establishment parties explain why a centralization of agenda control succeeded in the French National Assembly in 1958 but not during previous reform attempts or in the German Reichstag during the Weimar Republic. The absence of obstruction (in the French case) or legislators’ procedural response to it (in the German case) prevented any substantial reform in the interwar years. Only when anti-system obstruction triggered a procedural response did the centralization of agenda control succeed in France. Once procedural path changes occurred, legislators adapted by developing a preference for talk (in the plenary) or work (in committees). This explains why neither the disappearance of the anti-system threat in the British House of Commons nor the emergence of a Communist party in the Swedish Riksdag affected the respective procedural paths chosen prior to 1917.
