5 Surprising Facts About the Demak Sultanate Rarely Discussed in Schools

Raden Patah, the figure recognised as the founder of Demak, actually had a rather complicated life story. He is believed to be the son of the last Majapahit king, Prabu Brawijaya V, by a concubine of Champa descent. Due to internal problems within the palace, his pregnant mother was banished from the court and ultimately raised Raden Patah far from the royal environment. Some historians, as recorded in Chinese chronicles, even refer to his childhood name as Jin Bun, meaning ‘strong man’—an indication that the Demak lineage may also have roots in the Muslim Chinese community that had long settled on the north coast of Java. After reaching adulthood, with the full support of the Wali Songo, Raden Patah was formally appointed as the first ruler of Demak with a lengthy title laden with religious significance, reflecting his position not just as a king, but also as a spiritual leader.

Many people only recognise two names from Demak: Raden Patah and Sultan Trenggana. Yet between them stood a compelling figure: Pati Unus, Raden Patah’s son, who ascended the throne after his father’s death. Pati Unus was known as a brave commander who earned the title Pangeran Sabrang Lor for his courage in crossing the sea to wage war. In 1521, he personally led a second attack on Malacca to recapture it from the Portuguese, a mission that ended tragically with his death in battle. After Pati Unus fell, Sultan Trenggana took the throne and brought Demak to its peak of glory. The line of rulers includes Raden Patah, Pati Unus, Sultan Trenggana, Sunan Prawata, and Arya Penangsang. Interestingly, the centre of government did not remain static; it moved from Bintoro to Demak Prawata, and finally to Jipang as power struggles intensified towards the sultanate’s end.

One of the most overlooked facts about Demak is its role in the birth of the name Jakarta. In 1527, a combined force from Demak and Cirebon under the command of Fatahillah, acting on the direct orders of Sultan Trenggana, succeeded in driving the Portuguese out of the port of Sunda Kelapa. To mark this victory, the port was renamed Jayakarta, meaning ‘complete victory’. This name later evolved into Batavia during the colonial era and eventually became Jakarta, the capital of Indonesia. Thus, indirectly, the legacy of Demak is embedded in the name of the nation’s capital city.

The Demak Sultanate did not fall due to defeat by a foreign power, but rather through bloodshed within its own family. After Sultan Trenggana died in 1546, the throne passed to Sunan Prawata. His reign was short-lived, however, as he was murdered by his cousin, Arya Penangsang, who believed he had a stronger claim to the throne. Arya Penangsang’s turbulent rule sparked resistance from other factions, including Jaka Tingkir, who later founded the Sultanate of Pajang. Following Arya Penangsang’s defeat, Demak’s existence as an independent kingdom came to an end, and political-Islamic power in Java shifted to its successor states. It is ironic that a kingdom which fought so fiercely against Portuguese colonial ambitions at sea ultimately collapsed due to something far simpler: ambition for power within its own family.

Despite its relatively short lifespan, physical and symbolic traces of the Demak Sultanate remain visible today. The Grand Mosque of Demak still stands as one of the most important historical Islamic sites in Java. The name Jayakarta, which evolved into Jakarta, is an indirect legacy of the Demak-Cirebon victory over the Portuguese. Furthermore, the pattern of ulama and ruler relations established during this period was later adopted by successor sultanates such as Pajang, Mataram, Cirebon, and Banten.
