[2] She was born to king Janmejaya I of the Somavamshi dynasty kingdom.
When her spouse died, he was succeeded by his brother Sivakaradeva III (r. 882-890).
According to the Brahmesvara inscription of Somavamsi from the reign of King Udyotakesari Mahabhavagupta, her father Janmejaya “drew to himself the fortune of the King of Odra country, who was killed in battle by his Kunta.” Her reign was supported by her father.
When the Kalachuri king Sankaragana invaded Kosala, and her father Janmejaya I engaged in combat with the aggressor, the Bhauma-Kara dynasty’s officials supported a coup by the queen's sister-in-law, the widow of Sivakaradeva III, who deposed Tribhuvana Mahadevi II and replaced her on the throne as Tribhuvana Mahadevi III.
[3] After the deposition, former queen Tribhuvana Mahadevi II returned to live with her father in Kosala.
