with his mother was annulled, making him an illegitimate child. Also pushed by the local nobility, Stefan started the rebellion against his father in 1314 which was quickly quashed with Milutin personally heading the army. Stefan fled across the Bojana river but Milutin offered negotiations. Stefan accepted, but Milutin shackled him instead and ordered for Stefan to be blinded (which wasn't conducted properly due to the bribery) and expelled to Constantinople. Milutin then appointed Konstantin to administer Zeta. Konstantin was declared King of Zeta and minted his own money in Shkodër. Silver coins represented Konstantin sitting on the throne had inscriptions "Dominus rex Constantinus" and "Sanctus Stefanus Scutari" on the obverse and reverse, respectively. He was also sent by his father in diplomatic missions. In October 1321, when Milutin died, Konstantin was in Constantinople, hiring additional military forces for the warfare with the Hungarians. However, neither the historians, nor Milutin himself, apparently held no high regard for Konstantin. Though his father gave him Zeta to rule, he didn't declare him heir apparent right away. He seemingly had no better opinion on his other son, Stefan, as even during the time when both of his sons were in Serbia, Milutin was prospecting to appoint one of the Byzantine princes as his heir. His last mother-in-law, Byzantine empress consort Irene, mother of Milutin's another child bride Simonis, sent in time two of her sons to Milutin. Younger prince Demetrios refused the post as he disliked Serbia, and the attempt with the older prince, Theodore, also failed. On 12 March 1316, Milutin's older brother, king Stefan Dragutin, died. As per the power-sharing 1282 Deževa Agreement between the brothers, Dragutin's heir, Vladislav II, was to become the paramount king of Serbia and not only of the northern Realm of Stefan Dragutin, while Milutin will accept the vassal position to his nephew. Milutin had no intention of following the agreement. Not only that he didn't accept the kingship of Vladislav, he attacked new king's domain in the north and captured him. Only after all this, when he was left without other possibilities (blind and expelled Stefan, failed attempts with brothers-in-law, possible pretenders from Dragutin's line), Milutin named Konstantin as his heir, and began to prepare him for succession. Naming happened sometime in 1317 or after, as Milutin mentions Konstantin as his heir in his endowment to the Bari Cathedral which included a silver altar with
