Bhanumati was the daughter of the King of Kamboj. When she came of age, the King arranged for a Swayamvar for Bhanumati to pick her groom. Among those invited was Duryodhan, who was besotted with Bhanumati’s beauty. Sadly for him though, Bhanumati moved ahead without so much as a second glance at him. Enraged, Duryodhan abducted Bhanumati and fled the scene, leaving behind Karna to battle it out with the other Kings who had assembled for the Swayamvar.
Eventually Duryodhan married Bhanumati and the couple had two children- a boy named Lakshman and a girl named Lakshmana. Lakshman was slain by Abhimanyu during the Mahabharat war, while Lakshmana was abducted by Krishna’s son Samb who married her. After the war of Mahabharat this maariage of Samb and Lakshmana became the reason for end of Yadav Vansh. Samb was not very happy with Shri Krishna for helping Pandavs win the war against his in Laws and he started fighting within the family (Can be read in detail in Mausal Parva of Mahabharat).
And thus was born Bhanumati’s कुनबा. Bhanumati, who, unwillingly became Duryodhan’s wife. Duryodhan, who abducted Bhanumati relying on Karna’s strength. Lakshmana, their daughter, who eventually became Krishna’s daughter in law, and Lakshman, her son, who died during the Mahabharat war.
