Güyük Khan
When the Great Khatun Töregene invited Batu to elect the next Emperor of the Mongol Empire in 1242, he declined to attend the kurultai and instead stayed at the Volga River. Although Batu excused himself by saying he was suffering from old age and illness, it seems that he did not support the election of Güyük Khan. Güyük and Büri, a grandson of Chagatai Khan, had quarreled violently with Batu at a victory banquet during the Mongol occupation of Eastern Europe. He sent his brothers to the kurultai, and the new Khagan of the Mongols was elected in 1246.
