Decline

Following Hayam Wuruk's death AD 1389, Majapahit power entered a period of decline with conflict over succession. Hayam Wuruk was succeeded by the crown princess Kusumawardhani, who married a relative, Prince Wikramawardhana. Hayam Wuruk also had a son from his previous marriage, crown prince Wirabhumi, who also claimed the throne. A civil war, called Paregreg, is thought to have occurred from 1405 to 1406,^[8] of which Wikramawardhana was victorious and Wirabhumi was caught and decapitated. The civil war has weakened Majapahit grip on its outer vassals and colonies.
During the reign of Wikramawardhana, the series of Ming armada naval expeditions led by Zheng He, a Muslim Chinese admiral, arrived in Java for several times spanned the period from 1405 to 1433. By 1430 Zheng He's expeditions has established Muslim Chinese and Arab communities in northern ports of Java such as in Semarang, Demak, Tuban, and Ampel, thus Islam began to gain foothold on Java's northern coast.
Wikramawardhana ruled to 1426 AD and was succeeded by his daughter Suhita, who ruled from 1426 to 1447 AD. She was the second child of Wikramawardhana by a concubine who was the daughter of Wirabhumi. In 1447, Suhita died and was succeeded by Kertawijaya, her brother. He ruled until 1451 AD. After Kertawijaya died, Bhre Pamotan became a king with formal name Rajasawardhana and ruled at Kahuripan. He died in 1453 AD. A three-year kingless period was possibly the result of a succession crisis. Girisawardhana, son of Kertawijaya, came to power 1456. He died in 1466 AD and was succeeded by Singhawikramawardhana. In 1468 AD Prince Kertabhumi rebelled against Singhawikramawardhana promoting himself king of Majapahit.
In western part of the crumbling empire, Majapahit found itself unable to control the rising power of the Sultanate of Malacca that in mid 15th century began to gain effective control of Malacca strait and expands its influence to Sumatra. Several other former Majapahit vassals and colonies began to released themself from Majapahit domination and suzerainty.

Singhawikramawardhana moved the Kingdom’s capital further inland to Daha (the former capital of Kediri kingdom) and continued his rule until he was succeeded by his son Ranawijaya in 1474 AD. In 1478 AD he defeated Kertabhumi and reunited Majapahit as one Kingdom. Ranawijaya ruled from 1474 AD to 1519 AD with the formal name Girindrawardhana. Nevertheless, Majapahit's power had declined through these dynastic conflicts and the growing power of the north-coastal kingdoms in Java.
Dates for the end of the Majapahit Empire range from 1478 (that is, 1400 Saka, the ends of centuries being considered a time when changes of dynasty or courts normally ended^[20]) to 1527. The year is marked among Javanese today with candrasengkala "sirna ilang kertaning bumi" (the wealth of earth disappeared and diminished) (sirna = 0, ilang = 0, kerta = 4, bumi = 1). According Jiyu and Petak inscription, Ranawijaya claimed that he already defeat Kertabhumi ^[21] and move capital to Daha. This event to led the war between Sultanate of Demak and Daha, since Demak ruler was the descendants of Kertabhumi. The battle was won by Demak in 1527.^[22] A large number of courtiers, artisans, priests, and members of the royalty moved east to the island of Bali. The refugees probably fled to avoid Demak retribution for their support for Ranawijaya against Kertabhumi.
With the fall of Daha crushed by Demak in 1527, the Muslim emerging forces finally defeated the remnants of the Majapahit kingdom in the early 16th century.^[23] Demak under the leadership of Raden (later crowned as Sultan) Patah (Arabic name: Fatah) was acknowledged as the legitimate successor of Majapahit. According to Babad Tanah Jawi and Demak tradition, the source of Patah's legitimacy was because their first sultan, Raden Patah, was the son of Majapahit king Brawijaya V with a Chinese concubine. Another argument supports Demak as the successor of Majapahit; the rising Demak sultanate was easily accepted as the nominal regional ruler, as Demak was the former Majapahit vassal and located near the former Majapahit realm in Eastern Java.
Demak established itself as the regional power and the first Islamic sultanate in Java. After the fall of Majapahit, the Hindu kingdoms in Java only remained in Blambangan on eastern edge and Pajajaran in western part. Gradually Hindu communities began to retreat to mountain ranges in East Java and also to neighboring island of Bali. A small enclave of Hindu communities still remain in Tengger mountain range.
