[4][5] Zidanta was married to the daughter of Hantili, brother-in-law to King Mursili I.
Zidanta encouraged and helped Hantili to kill Mursili and seize the throne.
At the end of Hantili’s life, Zidanta killed Pišeni, the legitimate heir, together with Pišeni’s children and foremost servants, and so made it possible for himself to become king.
His reign is thought to have lasted about 10 years around 1560-1550 BC (middle chronology).
