Ariq Böke
Mubarak Shah was too young to rule and state affairs were managed by his mother Orghana. In 1260, Ariq Böke replaced Mubarak Shah with Alghu, a grandson of Chagatai Khan. Alghu rebelled against Ariq Böke upon securing power and defected to Kublai Khan's side in the Toluid Civil War. Ariq Böke attacked him and while Alghu experienced initial success in fending off the Ariq Böke's army, was forced to flee to Samarkand in 1263. Ariq Böke devastated the Ili region in his absence. Alghu was able to recruit a new army with the aid of Orghana and Mas'ud Yalavach. He then went on to defeat an invasion by Kaidu and drive out Ariq Böke, who surrendered to Kublai in 1264. Alghu died in 1265 and Orghana placed her son, Mubarak Shah, on the throne once again.
