The statue of Harihara, the god combination of Shiva and Vishnu. It was the mortuary deified portrayal of Kertarajasa. Originally located at Candi Simping, Blitar and the statue is now preserved at the National Museum of Indonesia.

After defeating the Melayu Kingdom^[13] in Sumatra in 1290, Singhasari became the most powerful kingdom in the region. Kublai Khan, the Great Khan of the Mongol Empire and the Emperor of the Mongol Yuan Dynasty, challenged Singhasari by sending emissaries demanding tribute. Kertanegara, the last ruler of Singhasari, refused to pay the tribute, insulted the Mongol envoy and challenged the Khan instead. As the response, in 1293, Kublai Khan sent a massive expedition of 1,000 ships to Java.
By that time, Jayakatwang, the Adipati (Duke) of Kediri, a vassal state of Singhasari, had usurped and killed Kertanagara. After being pardoned by Jayakatwang with the aid of Madura's regent, Arya Wiraraja; Raden Wijaya, Kertanegara's son-in-law, was given the land of Tarik timberland. He then opened that vast timberland and built a new village there. The village was named Majapahit, which was taken from a fruit name that had a bitter taste in that timberland (maja is the fruit name and pahit means bitter). When the Mongolian Yuan army sent by Kublai Khan arrived, Wijaya allied himself with the army to fight against Jayakatwang. Once Jayakatwang was destroyed, Raden Wijaya forced his allies to withdraw from Java by launching a surprise attack.^[14] Yuan's army had to withdraw in confusion as they were in hostile territory. It was also their last chance to catch the monsoon winds home; otherwise, they would have had to wait for another six months on a hostile island.
In AD 1293, Raden Wijaya founded a stronghold with the capital Majapahit. The exact date used as the birth of the Majapahit kingdom is the day of his coronation, the 15th of Kartika month in the year 1215 using the Javanese çaka calendar, which equates to November 10, 1293. During his coronation he was given formal name Kertarajasa Jayawardhana. The new kingdom faced challenges. Some of Kertarajasa's most trusted men, including Ranggalawe, Sora, and Nambi rebelled against him, though unsuccessfully. It was suspected that the mahapati (equal with prime minister) Halayudha set the conspiracy to overthrow all of the king's opponents, to gain the highest position in the government. However, following the death of the last rebel Kuti, Halayudha was captured and jailed for his tricks, and then sentenced to death.^[14] Wijaya himself died in AD 1309.
According to tradition, Wijaya's son and successor, Jayanegara was notorious for immorality. One of his sinful acts was his desire on taking his own stepsisters as wives. He was entitled Kala Gemet, or "weak villain". Approximately during Jayanegara's reign, the Italian Friar Odoric of Pordenone visited Majapahit court in Java. In AD 1328, Jayanegara was murdered by his doctor, Tanca. His stepmother, Gayatri Rajapatni, was supposed to replace him, but Rajapatni retired from court to become a Bhikkhuni. Rajapatni appointed her daughter, Tribhuwana Wijayatunggadewi, or known in her formal name as Tribhuwannottungadewi Jayawishnuwardhani, as the queen of Majapahit under Rajapatni's auspices. Tribhuwana appointed Gajah Mada as the Prime Minister in 1336. During his inauguration Gajah Mada declared his Sumpah Palapa, revealing his plan to expand Majapahit realm and building an empire. During Tribhuwana’s rule, the Majapahit kingdom grew much larger and became famous in the area. Tribhuwana ruled Majapahit until the death of her mother in AD 1350. She abdicated the throne in favour of her son, Hayam Wuruk.
