Jarruci is generally regarded as a judge; however, the post included not only judicial duties but also management of census registers and fiscal administration. Although the relation of census registers to jarruci has not attract researchers' attention to date, it is a matter of no small importance in the structural fabric of the Mongol Empire. In the Secret History of the Mongols, there is a description of the origin of jarruci. It seems that Cinggis Qan decreed to share out people to his clan and establish jarruci at a time. It shows that the jarruci's two duties were interrelation, that is to apportion qubi (assigned territories, people and possessions) shared out among the imperial princes and to try transgressors by jarru. The nomadic groups multilayeredly formed by sharing among the Cinggised lines and dominant noyans were called ulus. One ulus corresponded to each jarruci's jurisdictional limits. Jarruci's administrative role was closely connected to the structure of the Mongol Empire composed of multilayered uluses. From superordinate ulus to subordinate ulus, sharing olja (spoils) were shared as qubi. At the connecting points of such a multilayered social structure, jarruci apportioned qubi justly, and kept order among the ulus. Jarruci investigated olja and reported the results to the qan of his ulus, then carried out the apportionment of qubi as ordered by the qan. At the same time, jarruci were dispatched from subordinate ulus to superordinate ulus to ensure qubi of his ulus. Jarruci, in other words, redistributed qubi inside their own ulus and as a dispatched offical ensured qubi outside their own ulus. Ulus and ulus, sedentary territories and nomadic territories were connected by jarruci, and thereby the Mongol Empire was able to maintain a certain degree of uniformity as a single state.
