Archaeological evidence however confirms only a smaller empire of the Irrawaddy valley and nearer periphery. Anawrahta's victory terracotta votive tablets emblazoned with his name in Sanskrit have been found along the Tenasserim coastline in the south, Katha in the north, Thazi in the east and Minbu in the west. In the northeast, a series of 43 forts Anawrahta established along the eastern foothills, of which 33 still exist as villages, reveal the effective extent of his authority. Moreover, most scholars attribute Pagan's control of peripheral regions (Arakan, Shan Hills) to later kings—Arakan to Alaungsithu, and cis-Salween Shan Hills to Narapatisithu. (Even those latter-day kings may not have had more than nominal control over the farther peripheral regions. For example, some scholars such as Victor Lieberman argue that Pagan did not have any "effective authority" over Arakan.)
