Women in Mahabharata - Sutanu
She is one of the daughters of Padmavati and Ugrasena. She is also sometimes referred to as Ugrasenaa or Sugaatri. She is married to Akroora, as part of an alliance arranged by Krishna, from Vrindavana.
Her sons are Prasena and Upadeva.
Krishna finds out that the politically neutral Akroora has been nursing a silent 'crush' on her for quite some time, but has been turned down by Kamsa multiple times. Krishna uses his influence on other ministers, sending messages through Vasudeva, to increase pressure on Kamsa until the latter finally relents. Grateful, Akroora secretly agrees to stand by Krishna in the subsequent counter-coup.
In this version of the story, it seems as though Sutanu is the same age or maybe even a little younger than Krishna, making way for another theory: perhaps she wasn't a daughter, but rather the granddaughter of Ugrasena, and a daughter of Kamsa. This would explain why she is still unmarried, and why Kamsa is so reluctant to marry her to Akroora, who is his friend (as far as Kamsa knows) but quite close to him in age.
The true circumstances of her marriage is elusive to researchers since, based on the timeline presented in the story however, Krishna would be 14/15/16/17, remotely arranging a marriage for two people only slightly younger than his parents.
But, Krishna, I must say, not many people can boast of having gotten their uncle married! 😂
P. S. she is not to be confused with Yudhishthira's daughter, or apparently another daughter of Ugrasena with the same name who is married to Vasudeva (and somehow the mother of Paundraka??).
