Batu Khan

Timeline

1. 1227Jochi's appanage (west of the Irtysh River) · Ulus of JochiAfter Jochi's death in 1227, Batu, as Genghis Khan's eldest grandson, inherited Jochi's lands west of the Irtysh River and his armies, becoming the de facto leader of the Kipchak tribes and Jochid forces, an important branch in the Mongol Empire's appanage structure by the late 1220s.
2. 1229Köde' Aral (kurultai site) · Mongolian PlateauAfter Genghis Khan's death in 1229, the princes assembled at Köde' Aral and elected Ögedei as Great Khan. Batu attended the kurultai as head of the Jochid line, supported Ögedei's accession, and participated in high imperial politics around 1229, consolidating the Jochids' independent position on the Kipchak Steppe.
3. 1230Northern China (Jin front) · Northern ChinaIn 1230 Ögedei launched a general offensive against Jin; Batu led Jochid forces south from the north, coordinating with Tolui and other princes to besiege Weizhou and other places. This showed that by the late 1220s Batu had grown from a young prince who inherited an appanage into an important participant in imperial military operations, accumulating experience for his later western campaigns.
