Hattusili III
When his brother Muwattalli II became king, Hattusili III was appointed to govern over the northern lands of the Hittite empire. While this initially caused minor controversy among the locals and the ousted governor, Hattusili III was quick to quash dissidence with military force and turned his eyes towards conquering new territories surrounding the northern Hittite lands. When the King made the decision to move the capital from Hattusa to Tarhuntassa, Hattusili III was left to quash the rebellions that arose due to this decision. Subsequently, Hattusili III was made King of the northern territories by his brother Muwattalli II.
