[1] She was the first daughter of King Kertarajasa Jayawardhana, the founder of Majapahit Empire by his principal wife Dyah Gayatri who held the title of Rajapatni.

She was the eldest of Wijaya's offspring, her younger sister namely Dyah Wiyat, both were the daughter of Rajapatni Gayatri, while her half-brother was Jayanagara, the son of Indreswari.

According to Nagarakretagama canto 48 stanza 1, her half-brother Jayanegara succeeded to the throne upon the death of her father in 1309, while she and her sister gained the title of Paduka Bhatara simply referred to Bhre.

The practice of half-sibling marriage is abhorred in Javanese tradition, subsequently the council of royal elders led by Queen Dowager Gayatri spoke strongly against the king's wishes.

The motivation of Jayanegara's wish was not clear — it might have been his way to ensure his throne's legitimacy by preventing rivals from his half sisters' suitors.

Nevertheless, Jayanegara went further to prevent his half-sisters' courtship by confining Tya and Wiyat in the kaputren (ladies quarter) of the palace, locking them in a well-guarded inner compound, and denying the two princesses contact and access to the court and public affairs.

By that time, Rajapatni Gayatri was the last surviving elder and matriarch of Majapahit royal family, and supposed to secure the throne since Jayanegara had no sons.

Princess Tya ascended to throne under her new regnal name Tribhuwannottunggadewi Jayawishnuwardhani, which means "The exalted goddess of three worlds which the glory of Vishnu radiates".

The decision was partly to resolve the competition between Gajah Mada and Ra Kembar for the army general position to crush Sadeng.

This public humiliation enraged Gajah Mada, resulting in a duel, warranted by Tribhuwana, which led to the death of Ra Kembar and the execution of others that opposed his authority.

Majapahit expansion continued under the reign of Hayam Wuruk, reaching Lamuri (present-day Aceh) in the West and Wanin (Onin Peninsula, Papua) in the East.
