While Alexis de Tocqueville is most famous for his analysis of American democracy, this chapter argues that when it came to France, he preferred parliamentarism over the American constitutional model. During his long career in French parliamentary politics, Tocqueville in fact developed a distinctive theory of parliamentarism, which was different from Constant’s, but which also differed from the conception of parliamentarism propagated by Constant’s great rivals, the Doctrinaires. Tocqueville rejected Constant’s argument for a monarch who reigned but did not govern. However, he agreed with Constant that corruption posed a severe threat to the survival of French parliamentarism.
