The royal authority attenuated further in farther "naingngans": Arakan, Chin Hills, Kachin Hills, and Shan Hills. These were tributary lands over which the crown only had a "largely ritual" or nominal sovereignty. In general, the king of Pagan received a periodic nominal tribute but had "no substantive authority", for example, on such matters as the selection of deputies, successors, or levels of taxation. Pagan largely stayed out of the affairs of these outlying states, only interfering when there were outright revolts, such as Arakan and Martaban in the late 1250s or northern Kachin Hills in 1277.
