Kosala Devī was born to the King of Kosala, Maha-Kosala. She was the sister of King Prasenajit who succeeded her father as the ruler of Kosala. She was married to King Bimbisara, and brought Kashi as dowry in the marriage.[2] She became his principal queen.

Buddhist tradition makes Ajatashatru a son of hers;[3] the Jain tradition make him a son of her husband's second wife, Chellana.[4] Her niece, Princess Vajira, the daughter of Pasenadi (Prasenjit) was given in marriage to Ajatashatru.[5]

When her husband Bimbisara died at the hands of his own son Ajatashatru, Empress Kosala Devi has said to have died of grief out of her love for her husband. The government revenues of an estate in Kashi had been settled upon by her father as pin money on her marriage. At her death, the payment of course ceased. Ajatashatru then invaded Kashi.[5]
