Argentina's constitution dates back to 1853 and has rarely been formally suspended. Nevertheless, constitutionalism has almost never existed in Argentina, as virtually each government's power exceeded the strictures of the constitution. Presidential omnipotence, state violence, political instability, the absence of the rule of law, and political clientelism have been recurrent problems throughout Argentine history. Peronism, a quintessential Argentine movement, has likewise hindered constitutionalism. The article explores historical, legal, political, and sociological factors behind the failed invigoration of Argentina's constitution.
