Patrimonial government occurs when the ruler's household expands with the household administration giving rise to governmental offices. All officials are personal dependents or favourites of the ruler, appointed by him. Their interactions with the ruler are based on paternal authority and filial dependence. The officials treat their work as a personal service to the ruler. The ruler has complete control over the officials; he empowers them from case to case, assigns specific tasks, promotes and demotes. They have no rights, rather they have privileges granted and withdrawn by the ruler. It is rare to discover any clear and stable hierarchy and responsibility in the deluge of official titles of most patrimonial administrations.
