Tribhuwana Wijayatunggadewi

When Jayanegara died without issue in 1328, the succession reverted to the daughters of Kertarajasa by Gayatri Rajapatni, the youngest of Kertanegara's daughters. Gayatri herself, the senior figure of the royal house, had taken vows as a Buddhist nun, and the Nagarakretagama explains that her daughter Tribhuwana Wijayatunggadewi occupied the throne as her representative. The arrangement made Tribhuwana queen regnant in practice for over two decades, ruling jointly in spirit with a mother whose authority remained the dynasty's anchor.

Her reign opened with crisis. In 1331 the regions of Sadeng and Keta rose in revolt; the campaign that crushed them became the proving ground for Gajah Mada, who emerged from the affair as mahapatih, chief minister of the realm. The Pararaton attaches to his elevation the famous Palapa oath, in which he vowed to abstain from worldly pleasure until the lands beyond Java — it names Gurun, Seran, Tanjungpura, Haru, Pahang, Dompo, Bali, Sunda, Palembang, and Tumasik — were brought under Majapahit. Whatever the oath's literal historicity, the policy it encodes is visible in the record: in 1343 Majapahit forces conquered Bali, beginning the overseas expansion that defined the kingdom's imperial age.

Tribhuwana married Cakradhara, who bore the title Kertawardhana as Bhre Tumapel. Their son Hayam Wuruk, born in 1334, was raised as heir from infancy; a daughter, Dyah Nertaja, became mother of the later king Wikramawardhana. Tribhuwana is one of the rare premodern Southeast Asian rulers depicted in surviving statuary, traditionally identified with a celebrated image of the goddess Parvati from Rimbi.

When Gayatri Rajapatni died in 1350, the formal basis of Tribhuwana's rule lapsed, and she stepped aside for her sixteen-year-old son. She did not leave public life: as Bhre Kahuripan she sat in the council of royal elders that the Nagarakretagama shows advising Hayam Wuruk's court. The date of her death is not securely recorded. Her regency had transformed a troubled Javanese kingdom into an expanding maritime power, and the partnership she forged with Gajah Mada set the pattern her son inherited.
