The
Kutai Martapura Kingdom (399–1635; locally known as ) is a 4th-century Hindu kingdom located in the Kutai area,
East Kalimantan. Its capital is believed to be the current district located in
Kutai Kartanegara Regency and is one of the earliest kingdoms in Indonesian history. Muara Kaman district which is currently one of the many districts in Kutai Kartanegara Regency is proven to be the place where the capital of the kingdom once stood, it is proven by an ancient remnant of a
megalith stone known as
Lesong Batu, believed to have been used to make the
inscriptions during the 4th century. The seven stone pillars, or ('sacrificial posts'), have been found in Kutai, Kaman Estuary, near the
Mahakam River. The plinths bear an inscription in the Indic
Pallava script, reading "a gift to the
Brahmin priests" in
Sanskrit. The style of the script has been dated to the last half the 4th century. It is believed these religions were brought to Indonesia around the 2nd and 4th centuries, respectively, when Indian traders arrived on the islands of
Sumatra,
Java and
Sulawesi. The names of three rulers are known from the inscriptions. The first ruler mentioned is
Kudungga, the 'lord of men' (), his son Aśwawarman, styled the 'founder of the dynasty' () and grandson of the first and son of the later,
Mulavarman called the 'lord of kings' (). As the name "Kuṇḍungga" does not seem to be a name of Sanskrit-Hinduistic origin while the other two are, it is presumed he was a leader of local origin (
Dayak people) and it was his son Aśwawarman that adopted the Hinduistic belief. However, scientists and historians from the Dutch East Indies era to the Republic of Indonesia era concluded that the name Kundungga was the original name of Indonesian people from within Kalimantan, who had not been influenced by Indian culture. During the reign of King Mūlawarman, he is the one who let the inscriptions be made, and it was believed to be made by the
Brahmins which received alms from Mulavarman. While nothing of the military actions of his two predecessors is known, Raja Mūlawarman is stated to have conquered his neighbors in battle. He is also said to have increased the land of Kutai by a Vedic ritual known as the "
Ashvamedha", a ritual also performed by Indian rulers of the past. This ritual required a horse released to his land. The footsteps of the freely roaming horse were taken as evidence that this land belonged to his kingdom. Mulawarman was also known for his tribute of gold to his God. The name of his kingdom is not mentioned on the inscriptions nor do any other documents in other countries relate to a kingdom at this time in this region. It is not known what became of the kingdom after these pillars had been erected. It may be possible that the name Kutai, as in Tuñjung Kute of the 1365 Javanese
Majapahit poem "
Nagarakretagama" is as ancient and reflects the original name used a thousand years earlier. The
Lesong Batu is a
megalith stone located in Muara Kaman district,
Kutai Kartanegara Regency believed to be the remnants to make inscriptions during the 4th century. == Sultanate of Kutai Kartanegara ==
