The Phagmodru (Phag mo gru) myriarchy centered at Neudong (Sne'u gdong) was granted as an appanage to Hülegü in 1251. The area had already been associated with the Lang (Rlang) family, and with the waning of Ilkhanate influence it was ruled by this family, within the Mongol-Sakya framework headed by the Mongol appointed Pönchen (Dpon chen) at Sakya. The areas under Lang administration were continually encroached upon during the late 13th and early 14th centuries.
