In 1265, Chögyal Phagpa returned to Tibet and for the first time made an attempt to impose Sakya hegemony with the appointment of Shakya Bzang-po (a long time servant and ally of the Sakyas) as the dpon-chen ('great administrator') over Tibet in 1267. A census was conducted in 1268 and Tibet was divided into thirteen myriarchies (administrative districts, nominally containing 10,000 households). By the end of the century, Western Tibet lay under the effective control of imperial officials (almost certainly Tibetans) dependent on the 'Great Administrator', while the kingdoms of Guge and Pu-ran retained their internal autonomy.[44]
