Muwatalli II
After the reigns of both Manapa-Tarhunta and Mursilis II, Mursilis's successor Muwatalli II wrote a treaty with Alaksandu of Wilusa which mentioned that Manapa-Kurunta was now king in the Seha River Land. There is no documentation of any disturbance in the succession, so it is assumed that the succession was patrilineal, and that it transferred peacefully from father to son.
