Ariq Böke
This led to warfare between Kublai and Ariq Böke, which resulted in the destruction of the Mongolian capital at Karakorum. In Shaanxi and Sichuan, Möngke's army supported Ariq Böke. Kublai dispatched Lian Xixian to Shaanxi and Sichuan, where they executed Ariq Böke's civil administrator Liu Taiping and won over several wavering generals. To secure the southern front, Kublai attempted a diplomatic resolution and sent envoys to Hangzhou, but Jia broke his promise and arrested them. Kublai sent Abishqa as new khan to the Chagatai Khanate. Ariq Böke captured Abishqa, two other princes, and 100 men, and he had his own man, Alghu, crowned khan of Chagatai's territory. In the first armed clash between Ariq Böke and Kublai, Ariq Böke lost and his commander Alamdar was killed at the battle. In revenge, Ariq Böke had Abishqa executed. Kublai cut off supplies of food to Karakorum with the support of his cousin Kadan, son of Ögedei Khan. Karakorum quickly fell to Kublai's large army, but following Kublai's departure it was temporarily re-taken by Ariq Böke in 1261. Yizhou governor Li Tan revolted against Mongol rule in February 1262, and Kublai ordered his Chancellor Shi Tianze and Shi Shu to attack Li Tan. The two armies crushed Li Tan's revolt in just a few months and Li Tan was executed. These armies also executed Wang Wentong, Li Tan's father-in-law, who had been appointed the Chief Administrator of the Central Secretariat (Zhongshu Sheng) early in Kublai's reign and became one of Kublai's most trusted Han Chinese officials. The incident instilled in Kublai a distrust of ethnic Hans. After becoming emperor, Kublai banned granting the titles of and tithes to Han Chinese warlords.
