Langkasuka was an ancient Malay Hindu-Buddhist kingdom located in the Malay Peninsula. Langkasuka is generally believed to have existed from the 2nd to 15th century, and to have been established by descendants of Ashoka the Great.

The kingdom, along with Old Kedah, is among the earliest kingdoms founded on the Malay Peninsula. The exact location of the kingdom is of some debate, but archaeological discoveries at Yarang near Pattani, Thailand suggest a probable location. The kingdom is proposed to have been established in the 1st century, perhaps between 80 and 100 AD.

According to the legend given in the Kedah Annals, the kingdom was founded and named by Merong Mahawangsa. Another proposal derives the name from langkha and Ashoka, the Mauryan king who turned to Buddhism after his conquests. On this reading the early Indian colonisers of the Malayic Isthmus named the kingdom in his honour. Chinese historical sources provided some information on the kingdom and recorded a king Bhagadatta who sent envoys to the Chinese court.

Historical records The earliest and most detailed description of the kingdom comes from the Chinese Liang dynasty (502–557) record Liangshu, which refers to the kingdom of "Lang-ya-xiu" (, Middle Chinese: ). The record mentions that the kingdom was founded over 400 years earlier, which made its founding likely in the 2nd century AD. According to Liangshu, "Lang-ya-xiu" or Langkasuka was 30 days' journey from east to west, and 20 from north to south, 24,000 li in distance from Guangzhou. It mentions that Aloeswood (Aquilaria) and camphor were abundant in the kingdom, and its capital was described as being surrounded by walls to form a city with double gates, towers and pavilions. Both men and women in Langkasuka wore sarongs with their torsos bare and their hair loose, although the king and senior officials covered their shoulders with cloth and wore gold earrings and belts of gold cord. Women of high status wrapped themselves in cloth and wore jeweled girdles. It gives further information on some of its kings and also relates a story on a succession:

This king then ruled for more than 20 years. He was succeeded by his son, King Bhagadatta, who sent the first ambassadorial mission to China in 515. Further emissaries were sent in 523, 531, and 568.

The transcription of the kingdom's name in Chinese records changed over time. In the late seventh century, the Buddhist monk Yi Jing mentioned encountering three Chinese monks who lived in a place named Lang-jia-shu (郎伽戍).

A Song dynasty work Zhu fan zhi (published in 1225) gives a description of the country of Ling-ya-si-jia (凌牙斯加). It mentions that its people cut their hair and wrapped themselves in a piece of cloth, its products included elephant tusks, rhinoceros horns, types of wood and camphor, and their merchants traded in wine, rice, silk and porcelain. It also says that the country paid tribute to a country named Sanfoqi, which is usually interpreted to be Srivijaya. Original text: 凌牙斯國,自單馬令風帆六晝夜可到,亦有陸程。地主纏縵跣足;國人剪發,亦纏縵。地產象牙、犀角、速暫番、生香、腦子。番商興販,用酒、米、荷池、纈絹、甆器等為貨;各先以此等物准金銀,然後打博。如酒一墱,准銀一兩、准金二錢;米二墱准銀一兩,十墱准金一兩之類。歲貢三佛齊國。

Langkasuka was known as "Long-ya-xi-jiao" (龍牙犀角) in Daoyi Zhilüe from the Yuan dynasty (1279–1368); Original text: 峯頂內平而外聳,民環居之,如蟻附坡。厥田下等。氣候半熱。俗厚。男女椎髻,齒白,繫麻逸布。俗以結親為重。親戚之長者一日不見面,必携酒持物以問勞之。為長夜之飮,不見其醉。民煮海為鹽,釀秫為酒。有酋長。地產沈香,冠於諸番。次鶴頂、降眞、蜜糖、黃熟香頭。貿易之貸,用土印布、八都刺布、靑白花碗之屬。 and "Lang-xi-jia" (狼西加) during the Ming dynasty (1368–1644), as marked in Admiral Zheng He's Mao Kun map. Daoyi Zhilüe mentions that the natives of Langkasuka made salt from seawater and ferment rice wine, and produced hornbill casques, lakawood, honey and gharuwood. The people wore cotton from the Philippines and printed cloth from India and local sources.

"Langkasuka" was mentioned in the Malay text Hikayat Merong Mahawangsa, and it was referred to as "Lengkasuka" in the Javanese poem Nagarakretagama. Tamil sources name "Ilangasoka" as one of Rajendra Chola's conquests in his expedition against the Srivijaya empire. It was described as a kingdom that was "undaunted in fierce battles". Jaydipsinh Dodiya posited that the Langka mentioned in the ancient Sanskrit epic Ramayana may have been Langkasuka. Thai sources made no reference to Langkasuka, but Pattani, which may have succeeded Langkasuka, was identified by M.C. Chand Chirayu Rajani as one of the twelve Naksat cities under the influence of Nakhon Si Thammarat in Thai chronicles.

Outline of Langkasuka's history A brief outline of the history of Langkasuka can be determined from the limited historical records available. The kingdom is thought to have been founded some time early in the 2nd century AD, although the excavated material at Yarang begins only in the 7th century. It then underwent a period of decline due to the expansion of Funan in the early 3rd century. In the 6th century it experienced a resurgence and began to send emissaries to China. King Bhagadatta first established relations with China in 515 AD, with further emissaries sent in 523, 531 and 568. By the 8th century it had probably come under the control of the rising Srivijaya empire. In 1025 it was attacked by the armies of King Rajendra Chola I in his campaign against Srivijaya. In the 12th century, Langkasuka was a tributary to Srivijaya. The kingdom declined and how it ended is unclear with several theories being put up.

The Pasai Annals mentioned that Langkasuka was destroyed around 1370, but several historians contest this and believe that Langkasuka survived up to the 1470s. Some believed that Langkasuka remained under the control and influence of the Srivijaya Empire until the 14th century when it was conquered by the Majapahit Empire. Pattani may have conquered or been formed out of Langkasuka by the 15th century, and the areas of the kingdom that were not under the direct rule of Pattani are thought to have embraced Islam along with Kedah in 1474.

Location

Chinese and Arab sources placed the ancient kingdom on the east coast of the Malay Peninsula. The New Book of Tang mentions that Langkasuka bordered Pan Pan, and a map in the Ming dynasty military treatise Wubei Zhi locates it south of Songkla near the Pattani River. A 15th century Arab text similarly places the kingdom between Kelantan and Songkla. The only contradictory information comes from a later Malay text Hikayat Merong Mahawangsa which placed it on the west coast as the predecessor of modern Kedah, although its sovereign had some association with Pattani. Chinese, Arab and Indian sources all considered Kedah and Langkasuka to be separate geographical entities. The Javanese poem Nagarakretagama placed it north of Saiburi, however it appears to imply that it was originally located on the west coast but was transferred later to the east. Cœdès changed his mind about the Liangshus Lang-ya-xiu. In an article of 1918 he distinguished it, with Pelliot, from the southern kingdom and placed it at the base of the peninsula. His book of 1948 inclined instead to identify it with the Ling-ya-si-jia of Zhao Rugua and with Langkasuka, a view Briggs preferred.

In 1961, taking account of the various sources, the geographer and historian Paul Wheatley concluded that Langkasuka should be located near the modern town of Pattani. French archaeologist and historian Michel Jacq-Hergoualc'h concurred, and proposed the former estuary of the Pattani River near Yarang as the likely location of Langkasuka. He also suggested that whole area between Pattani, Saiburi and Yala may have been part of Langkasuka. Modern archaeological explorations have uncovered ruins near Yarang, a village fifteen kilometers south of Pattani, which may be of the city described in Liangshu. The city lay inland and connected to the rivers leading to the sea via canals. Silting of the waterways may have led to its decline.

Archaeology

Several archaeological expeditions were conducted in the 1960s to locate Langkasuka following Paul Wheatley's suggestion of its likely location. In 1963, Stewart Wavell led a Cambridge expedition to locate Langkasuka and Tambralinga. He described it in The Naga King's Daughter.

The Fine Arts Department of Thailand began investigating the Yarang area in 1989. The majority of the ruins were clustered in the vicinity of a hamlet called Ban Wat, and may have formed the nucleus of the city. Others were scattered further to the North at Ban Jalæ, and a couple more at Ban Prawæ. The excavations found various Buddhist structures and objects including votive tablets and sculptures, indicating a strong Buddhist presence in the kingdom. Objects related to Hindu worship were also found.

Many Chinese and Arab coins made of bronze have been found in the region, an indication of the commercial activity of the kingdom. Two silver Sassanid coins have also been found. The moated site covers about 0.9 km², lying 4.5 km from the Pattani River and 15 km from the sea, and carries 44 mounds identified as brick stūpas. Four have been excavated: Ban Jalae 2, about 7 m square; Ban Jalae 3, 13.15 m; Ban Jalae 8, 13.50 m; and Ban Wat 9, 12 m. The finds include votive tablets and miniature stūpas inscribed in Sanskrit in Pallava script, a stone bull, a bronze Avalokiteśvara and, inside mound no. 3, a few sherds of Persian turquoise-glazed ware. Locally made pots carrying a shared motif have been recovered at Yarang and at the hill sites of Khao Kha and Khao Si Wichai in the upper peninsula. The correspondence has been read as a link between the two areas in the late 6th and 7th centuries.

The excavated sequence in the Pattani basin begins in the 7th century. Siriporn Sanghiran, reporting a survey of 35 sites on the lower peninsula, notes an unexplained interval between the lowland settlement of about 300 BCE and the first historic states of the 7th century, and the 2019 field season was framed around closing it.

Kings of Langkasuka Below is the list of the eight rulers of Langkasuka, Merong and his descendants, according to the Kedah Annals:

King Merong Mahawangsa: A ruler from Rome who later settled in the Bujang Valley and founded the Kingdom of Langkasuka. He is said to be a descendant of Alexander the Great. He was later succeeded by his eldest son, Merong Mahapudisat. Merong then left for Rome, leaving his son the ruler of Langkasuka. King Merong Mahapudisat: He became the king of Langkasuka after his father, Merong Mahawangsa went back to Rome. He was the eldest son. Legends say that he was also the first king of Siam. King Ganjil Sarjuna: He was crowned king after his brother's death. He was the second eldest in the family. He founded the Gangga Negara kingdom. Raja Puteri (in English, King Princess): She became the King of Langkasuka after her brother Ganjil Sarjuna died. She is the youngest daughter in the family. She was also the first ruler of Pattani. King Seri Mahawangsa: He became the king of Langkasuka after his brother, Ganjil Sarjuna died. Seri Maha Inderawangsa: He is the son of Seri Mahawangsa. He was called "Raja Bersiong" or the Fanged King because of his cannibalistic behaviour of drinking human blood. He was the successor of Seri Mahawangsa, but because of his behaviour, the ministers of the kingdom had no choice but to revolt against him. He fled to Mount Jerai, where he remained hidden for a long time and later had a son, who was called Phra Ong Mahapudisat. His son, unknowing of his royal lineage, lived in his mother's village before being called to the palace and had his identity revealed. King Phra Ong Mahapudisat: After Seri Mahawangsa's death, Langkasuka needed a successor who had royal blood. Phra Ong Mahapudist was crowned king after his father's death. Sultan Mudzafar Shah, Phra Ong Mahawangsa: He was the only son of Phra Ong Mahapudisat. He was originally Hindu, but when Islam first came to the Malay Peninsula, he became a Muslim and changed his name to Sultan Mudzafar Shah, and the Kingdom of Langkasuka into the Kedah Sultanate.
