After her father had killed one of his sons and taken his wife as his own, he then killed his advisor Daiyuu for suspecting he had molested her. To prevent Daiyuu's family from taking revenge on him, he gave his daughter Samur in marriage to Daiyuu's son. Samur's husband was given command over the Oirats and made their taishi, or leader.
Since many of her clan were virtual prisoners of their guards, she convinced first her husband and then her son to launch campaigns to free them. After her son died in these struggles, she convinced her grandson Esen to become taishi. Samur supported him as he brought the Mongolian Plateau and most of the Silk Route under his control.
Though Esen first strove for unity between the Oirats and the Borjigin clan of his grandmother, he later turned against the Borjigin. and had several of its nobles killed. When his own daughter was about to give birth, he also intended to have the baby killed if it turned out to be male. Samur helped her great-granddaughter escape and hide. They first pretended a girl had been born. When it became known that this was not true, Samur took the boy to her ger for protection and finally entrusted him to Mongols loyal to the Borjigins to take him out of Esen's reach. The boy was Bayan-Mongke, who would be a direct ancestor of Dayan Khan.
Samur died around the same time as Esen.
