the emperor's rule after the Diet of Roncaglia ordered the restoration of imperial rights, including the emperor's rights to levy taxes in the Northern Italian towns. Géza sent his envoys to Barbarossa's camp and promised to dispatch further reinforcements against the rebellious towns. The death of Pope Adrian IV on 1 September 1159 caused a schism, because the college of the cardinals was divided: the majority of the cardinals was opposed to Barbarossa's policy, but a minority supported him. The first group elected Alexander III pope, but Barbarossa's supporters chose Victor IV. Emperor Frederick summoned a synod to Pavia to put an end to the schism. Géza sent his envoys to the church council where Victor IV was declared the lawful pope in February 1160. However, Lucas, Archbishop of Esztergom, remained loyal to Alexander III and persuaded Géza to start negotiations with the representatives of Alexander III. Géza only decided to change sides after most European monarchs, including the kings of Sicily, England and France, joined Alexander III. Géza's envoys announced his decision to Alexander III in early 1161, but Géza only informed the emperor of his recognition of Alexander III in the autumn of the same year. Géza's and Alexander III's envoys signed a concordat in the summer of 1161. According to that treaty, Géza promised that he would not depose or transfer prelates without the consent of the Holy See; on the other hand, the pope acknowledged that no papal legates could be sent to Hungary without the king's permission and the Hungarian prelates were only allowed to appeal to the Holy See with the king's consent. He also signed a truce for five years with the Byzantine Empire. Shortly before his death, Géza granted Dalmatia, Croatia and other territories to his younger son, Béla, as an appanage duchy. Géza died on 31 May 1162 and was buried in Székesfehérvár. Family Géza's wife, Euphrosyne of Kiev, was a daughter of Grand Prince Mstislav I of Kiev. She survived Géza and died around 1193. Their first child, Stephen, was born in the summer of 1147; he succeeded Géza in 1162. His younger brother, Béla, was born in about 1148; he inherited Hungary after the death of Stephen in 1172. Géza's third son and namesake, Géza, was born in the 1150s. The youngest son of Géza and Euphrosyne, Árpád, did not survive childhood. Géza's and Euphrosyne's oldest daughter, Elizabeth, was
