Hamengkubuwono IV, also spelled Hamengkubuwana IV (Yogyakarta, 3 April 1804 – Yogyakarta, 6 December 1823) was the fourth sultan of Yogyakarta, Indonesia, reigning from 1814 to 1823.
Born as Gusti Raden Mas Ibnu Jarot, he was the 18th son of Hamengkubuwono III, born from his queen consort, Gusti Kanjeng Ratu Kencono. He was the younger half brother of Prince Diponegoro. He succeeded his father when he was 10 years old. Due to his young age, Paku Alam I was appointed as his regent.[1]
His reign was a period of political deterioration that ultimately led up to the Java War. In his era, Patih Danureja IV acted violently and arbitrarily. He put his relatives in many court's important position. This pro-Dutch Danurejan family also supported the implementation of land rent system for private entrepreneurs, which inflicted a loss upon the poor subjects.[2]
In 20 January 1820, Paku Alam I gave up his position as sultan's regent. Hamengkubuwono IV's independent rule was only 2 years due to his sudden death on 6 December 1823, when he was on vacation, hence his posthumous title, Sinuhun Jarot, Seda Besiyar.[3]
Upon his premature death, rumours circulated that he had been poisoned. His three-year-old son, Hamengkubuwono V, ascended the throne amid controversy over who would act as regent.[4] Hamengkubuwono V was later succeeded by his brother, styled Hamengkubuwono VI.
In total, Hamengkubuwono IV had 1 queen consort, 8 concubines, and 13 children.
His only queen consort was Gusti Kanjeng Ratu Kencana later also known as GKR. Hageng (born 1802), daughter of Patih Danureja II and Gusti Kanjeng Ratu Hangger, daughter of Hamengkubuwono II, and had issues:
His concubines included:
