The King Who Asked His Sons for Their Youth
Yadu was the eldest son of King Yayati and his first wife Devayani, born into a family whose story is dominated by Yayati's own curse of premature old age, told in fuller detail elsewhere in this series through Yayati's own perspective.
When the sage Shukracharya, Devayani's father, cursed Yayati with old age for his infidelity with Sharmishtha, Yayati begged for and received a modification: he could pass the old age to someone else temporarily if that person agreed to take it, and receive their youth in exchange, until Yayati had satisfied his unfulfilled desires and was ready to grow old properly himself.
Yayati went to each of his five sons in turn and asked them to make this exchange. Yadu, as the eldest and the son of the wife whose father had originally cursed Yayati, was asked first.
Yadu's Refusal, and What It Cost His Descendants
Yadu refused. The texts give slightly different framings of his reasoning, some emphasizing that he simply did not want to give up his own youth and vitality for his father's sake, others suggesting he felt the request itself was unreasonable, a father asking sons to sacrifice their prime years to fund his continued indulgence in worldly pleasure. Whatever the exact reasoning, Yadu said no, and so did three of his four brothers when asked in turn: Turvasu, Druhyu and Anu all refused as well.
Only the youngest son, Puru, agreed, taking on his father's old age and giving Yayati his own youth in exchange, a decision covered in its own dedicated story elsewhere in this series and one that makes Puru the ancestor of the line that eventually produces the Kurus, the Pandavas and the Kauravas.
Yayati's response to his four refusing sons was a curse, delivered directly and without much ambiguity. He declared that since Yadu had refused to share even his youth with his own father, Yadu's descendants would never be fit to rule as kings, that the line would produce no sovereigns who held a throne by simple right of birth and succession, regardless of their strength, wealth or virtue.
This curse is the specific reason the tradition gives for why the Yadava dynasty, Yadu's own descendants, including Krishna and Balarama many generations later, never ruled Mathura or Dwarka as hereditary kings in the ordinary sense. Krishna, for all his divinity and influence, is consistently shown in the Mahabharata advising kings, brokering peace, commanding armies and shaping the outcome of the entire war, without ever holding a throne of his own by birthright. Ugrasena, later restored as king of Mathura after Kamsa's death, and the Yadava governance structure generally, functioned through councils and elected or restored rulers rather than a simple hereditary monarchy, a structural detail the tradition ties directly back to Yadu's ancient refusal.
The Name That Outlasted the Throne
Yadu did become the founder of a great and famous line despite the curse, since the Yadava dynasty, named directly after him, grows into one of the most significant lineages in the entire Puranic tradition, encompassing Krishna, Balarama, the entire Vrishni and Andhaka clans, and the sprawling network of Yadava branches spread across western and central India by the time of the Mahabharata.
The curse specifically barred kingship, not greatness, wealth, or spiritual significance, and the Yadavas as a whole are shown throughout the tradition as an extraordinarily powerful and prosperous people, simply one whose governance ran through councils, elders and restored or elected rulers rather than a straightforward hereditary crown.
That distinction matters for understanding Krishna's own political role in the Mahabharata. He is a kingmaker, a strategist, and by devotional tradition God himself, but he is consistently not a king in the way Yudhishthira or Duryodhana are kings, and the ancient story of his ancestor's single refusal to trade his youth is the reason the tradition gives for that specific, structural fact.
Quick Answers
Why did Yadu refuse to give Yayati his youth?+
The texts vary slightly, but the common thread is that Yadu did not want to give up his own vitality and prime years for his father's continued indulgence, and felt the request itself was unreasonable to make of a son.
What exactly was Yadu's curse?+
Yayati cursed that Yadu's descendants would never be fit to rule as kings by hereditary right, regardless of their power or virtue - a curse the tradition uses to explain why the Yadava dynasty, including Krishna, never held thrones the way the Kuru line did.
Is Krishna part of Yadu's cursed line?+
Yes. Krishna and Balarama both belong to the Yadava dynasty descended from Yadu, which is the tradition's explanation for why Krishna, despite his power and divinity, is never shown as a hereditary king in the Mahabharata.
Which of Yayati's sons agreed to the exchange?+
Only the youngest son, Puru, agreed to take on his father's old age in exchange for his own youth, which made Puru the ancestor of the line that produces the Kurus, Pandavas and Kauravas.
