Güyük

Timeline

1. 1229Qodun Aral · Mongolian PlateauIn 1229 Ögedei took the great khanate at Qodun Aral, and Güyük attended the kurultai as the eldest son, becoming the Ögedei line's clearest heir. Around 1229 he took part in state affairs beside the great khan, representing the Ögedei line in political coordination among the princes, and was a key figure in the empire's power transition at the end of the 1220s.
2. 1230Nanjing (Jin's Zhongdu, present-day Kaifeng) · HenanIn 1230 Ögedei launched a general offensive against the Jin, and Güyük led his troops south to besiege the Jin's Nanjing (Bianjing), advancing on separate routes with princes such as Tolui and Batu. Although the city did not fall immediately in 1230, this campaign gave Güyük experience in independent command and further established his priority among Ögedei's sons in both military and succession terms.
3. 1221–1228Khan's court of the Mongol Empire · Mongolian PlateauFrom 1221 to 1228 Güyük grew up beside Genghis Khan and Ögedei, and after Genghis Khan's death in 1227 he joined his father in handling imperial succession affairs. As Ögedei's eldest son, he appeared frequently at the khan's court and the princes' assemblies in the mid-to-late 1220s, regarded as the Ögedei line's preferred heir, until Ögedei formally took the khanate in 1229.
