Although Jacques Necker was one of the most important politicians during the Old Regime and the French Revolution, he was largely ignored as a political thinker. Yet, his work On Executive Power in Great States (1792) is arguably one of the most significant texts ever published on the issue of executive power in modern society. Written as the events of the French Revolution were still unfolding, it offers a unique and original perspective on the important topics such as executive power, constitutionalism, the rule of law, federalism, balance of power, and the dependence of liberty on morality and religion.
