'Darayisung Küdeng Khan' (c.
1520-
1570) was a legitimate successor to the throne in the
Mongol Empire.
When Bodi Alagh Khan, the legitimate ruler of the Mongols from the
Chahar, died in
1547 , Darayisung Küdeng Khan was set to follow. However
Altan Khan forced Darayisung Küdeng Khan to flee eastward. Four years later in
1551 Darayisung made a compromise with Altan accepting Altan's leadership in exchange for giving the title "Gegeen Khan" to him.
