Accounts of this vary across texts and traditions. This entry primarily follows Mahabharata, with other tellings (Puranic traditions (Harivamsha, Bhagavata Purana), Regional retellings) noted where relevant.
Sahadeva is the son of Jarasandha and the next king of Magadha. He is not the same person as the Pandava Sahadeva.
After Jarasandha's death, Krishna installed Sahadeva as the king of Magadha. He became an ally of the Pandavas and fought for them at Kurukshetra, where he fell.
