Historians of ancien régime France frequently pay tribute to the statebuilding capacities of that most talented and successful architect of absolute monarchy, Louis XIV. And it has long been recognised that, of the many institutions either created or inherited by the French Crown which were wont to claim a share in the handling of the daily affairs of the realm, the Council of State became, during the personal rule of Louis XIV, the chief vehicle for dispensing the royal will. Unfortunately, the sheer volume of matters dealt with by the Council has tended to discourage historians from making it the object of intensive study. More important is the fact that the machinery of Council after 1661 reflected two apparently contradictory tendencies: the peculiar personal and informal nature of Louis XIV's government, and the incipient formalism and bureaucratisation which were to become dominant factors in the government of late eighteenth-century France. The consequent flexibility and complexity of the system have certainly been important characteristics which have so far precluded a full and detailed explanation of the forms and functions of the Council and, more generally, its overall significance in the administration of absolute government.
