ムワタリ
After the Kaskians arrived to the kingdom's north, they twice attacked the city to the point where the kings had to move the royal seat to another city. Under Tudhaliya I, the Hittites moved north to Sapinuwa, returning later. Under Muwatalli II, they moved south to Tarhuntassa but assigned Hattusili III as governor over Hattusa. Mursili III returned the seat to Hattusa, where the kings remained until the end of the Hittite kingdom in the 12th century BC.
