Ariq Böke
After Möngke Khan died in 1259, the Toluid Civil War broke out between Kublai Khan and Ariq Böke. While Hulagu Khan of the Ilkhanate supported Kublai, Berke sided with Ariq Böke. There is evidence that Berke minted coins in Ariq Böke's name, but he remained militarily neutral. After the defeat of Ariq Böke in 1264, he freely acceded to Kublai's enthronement. However, some elites of the White Horde joined Ariq Böke's resistance.
