Kublai Khan
In 1260, Kublai Khan was proclaimed successor to the throne after the death of his brother Möngke, as was his youngest brother Ariq Böke. The succession war between him and Ariq Böke began. Kublai Khan won the war eventually, though his claim as the successor to Möngke was only partially recognized by the Mongols in the west. In 1271, Kublai Khan renamed his empire "Yuan", establishing the Yuan dynasty, instead of "Ikh Mongol Uls" (Great Mongolian Nation or Great Mongol Empire). After defeating his rivals and opponents in Mongolia and Northern China, Kublai Khan also wanted to continue his grandfather Genghis Khan's conquest of China. In 1267, Kublai Khan ordered Aju and the Song defector Liu Zheng to attack Xiangyang and Fencheng. General Lu Zende had levied corruption charges against Liu Zheng, the Luzhou prefect, causing Liu Zheng to defect to the Mongols in 1261
