The Khan has sent a massive one-thousand-ship ship expedition that arrives off the coast of Java in 1293.

Raden Wijaya, Kertanegara's son in law and supreme commander, himself a descendant of the kingdom’s founder Ken Anrok, after a brief exile in the favor of the Regent (Bupati) Arya Wiraraja of Madura, allies himself with the Mongols against Jayakatwang and, once Jayakatwang is destroyed and the invaders are feasting in victory, turns and forces his Mongol allies to withdraw from the isle after he launches a surprise attack.

The huge Mongol Army has to withdraw in confusion as they are in hostile land and it is the last opportunity for the monsoon that will allow them to depart for home, otherwise, they would have had to wait for another six months anchored off hostile territory.

Wijaya, or Vijaya, now establishes a state in eastern Java (to be known eventually as the Majapahit Empire), which is to become one of the greatest empires to arise from within the area covered by the modern territory of Indonesia.

The exact date used as the birth of the Majapahit kingdom is the day of his coronation, the fifteenth of Kartika month in the year 1215 using the Javanese çaka calendar, which equates to November 10, 1293.

During his coronation he is given the formal name Kertarajasa Jayawardhana.

King Kertarajasa takes all four daughters of Kertanegara as his wives, his first wife and prime queen consort Tribhuwaneswari, and her sisters; Prajnaparamita, Narendraduhita, and Gayatri Rajapatni the youngest.

He also takes a Sumatran Malay Dharmasraya princess named Dara Petak as his wife.
