Skocpol also argues that successful revolutions “paved the way for centralized, rational bureaucratic administration in the countries she studied.” According to Pfaff, many scholars have argued “while social revolutions removed the old governing class that was frequently an obstacle to significant administrative reforms, they often failed to deliver the degree of rational bureaucratic administration they promised.” In the case of the French Revolution, Skocpol claims that the revolution removed “medieval rubbish” and allowed modern bureaucratization to be created. It has been found, however, that there were “prerevolutionary trends towards greater administrative efficiency that, in some cases, may have been more disrupted by revolution than accelerated.”
