By Zanabazar's death in 1723, Urga was the Mongolia's preeminent monastery in terms of religious authority. A council of seven of the highest-ranking lamas (''Khamba Nomon Khan'', ''Ded Khamba'' and five ''Tsorj'') made most of the city's religious decisions. It had also become Outer Mongolia's commercial center. From 1733 to 1778, Urga moved in the vicinity of its present location. In 1754, the Erdene Shanzodba Yam  of Urga was given authority to supervise the administrative affairs of the Bogd's subjects. It also served as the city's chief judicial court. In 1758, the Qianlong Emperor appointed the Khalkha Vice General Sanzaidorj as the first Mongol amban of Urga with full authority to "oversee the Khuree and administer well all the Khutugtu's subjects".
