When Möngke died in 1259, Ariq Böke was elected Khan in the absence of his brothers, and had the support of most of the existing ministers and powerful families in the capital of Karakorum, such as Möngke's family, and other princes of the Golden family along with other forces in the capital of Karakorum including Torguud royal bodyguards and White Horde elites, as well as the Oirats, who were allied with him as one of the Oirat leaders was married to his daughter. However, when Kublai and Hulagu received news of Möngke's death, they aborted their own battles in order to return to the capital to decide the matter of succession. In May 1260, Kublai was elected khan by his own supporters, to rival the claim of Ariq Böke. A civil war subsequently broke out between the brothers for the leadership of the Empire. For example, when the Chagatai Khanate needed a new leader, Kublai attempted to send Abishqa, who was loyal to him. But Ariq Böke had Abishqa captured and eventually killed, and instead installed his own ally Alghu. Ariq Böke ordered Alghu to defend the area from both the forces of Hulagu, and the possible presence of Berke of the Golden Horde. But Alghu deserted Ariq Böke, killing his envoys for treasure, while Kaidu remained loyal to Ariq Böke. Alghu and Ariq Böke were soon in direct conflict, with Alghu winning the first engagement, but then at the second, Ariq Böke was victorious, and forced Alghu to flee westward.
