Ariq Böke
Berke also supported Great Khan claimant Ariq Böke in the Toluid Civil War, and he minted coins in the name of Ariq Böke. However Kublai defeated Ariq Böke by 1264. Kublai called both Hulagu and Berke to discuss Ariq Böke. However, both of them noted that they could not attend the Kurultai at the time, and a new Kurultai was never held.
