Siam Confederation (Xiān)
Siam Confederation, Xiān or Siam, not to be confused with the Kingdom of Siam, was a confederation of maritime-oriented port polities along the present Bay of Bangkok, including Ayodhya, Suphannabhum, and Phrip Phri, as well as Nakhon Si Thammarat, which became Siam in the late 13th century. It was the successor states of Qiān Zhī Fú at Si Thep, and others. Previous studies suggested that Xiān in Chinese dynasty records only referred to Sukhothai, but this presupposition has recently been rebutted.
Xiān was formed from city-states on the west Chao Phraya plain after the decline of Dvaravati in the 11th century. In 1178, the region was mentioned in the term San-lo 三濼, as recorded in the Chinese Lingwai Daida, in which Thai scholars suggest it was plausibly referred to Chaliang's new center, Sawankhalok. During the early Tang Dynasty, a polity named Xiū Luó Fēn, which was said to be located west of Chenla, sent tribute to the Chinese court. It had a large number of troops and customs that were roughly similar to those of Gē Luó Shě Fēn, which a Thai scholar identified with Dvaravati's Nakhon Pathom or Sambuka in the Bhavavarman II Inscription.
Xiān or Siam, which was also recorded as Suphan Buri and Nakhon Si Thammarat in the late 13th century, joined a federation with Lavo in 1351; this led to the formation of the Ayutthaya Kingdom with the federal seat at [Phra Nakhon Si Ayutthaya Kingdom|Ayutthaya (city)|Ayutthaya]. Phip Phli was demoted to a frontier city following the federative formation and was then governed by Suphan Buri, which was completely annexed into the Ayutthaya Kingdom in 1438, whereas Nakhon Si Thammarat maintained its vassal status throughout the Ayutthaya and Thonburi eras with short periods of independence and was demoted to Rattanakosin's province in 1782.
However, modern scholars suggest that the term Xiān mentioned in several Chinese and Đại Việt texts from 1149 until the official establishment of the Ayutthaya Kingdom in 1351 was potentially Lavo's new capital Ayodhya rather than Sukhothai Kingdom, Suphannabhum, and other initial Siamese polities.
Location
As described in the Chinese Daoyi Zhilüe, Xiān was surrounded by high mountains and deep valleys and was not located in the infertile land, which made the polities have to depend upon the neighbor Luó hú for the rice supply. It supports the people by commerce. Several studies propose that Xiān might refer to the Suphannabhum Kingdom centered in the present Suphanburi Province as some tributary missions sent to the Chinese in the Hongwu era were done under the name of King of Su-men-bang 蘇門邦 of Xiānluó hú, in which the term Su-men-bang has been identified with Suphanburi. In 1295, an envoy led by Xian's king Gan-mu-ding from Pi-ch'a-pu-li, which identified with Phetchaburi, visit the Chinese court. These correspond with the Chinese The Customs of Cambodia by Zhou Daguan in 1296–1297, who records that Xiān is on the southwest of Chenla.In the Jinakalamali, a local Pali chronicle of the northern Thai principality of Lan Na mentions siam-desa and siam-rattha refer to the "area ' or state ' of Siam," which one passage further identifies as the Sukhothai region.
History
Xiān city-states were formed around the 11th century following the fall of Qiān in the late Dvaravati period, which potentially declined due to the Menam Valley and the upper Malay peninsula being conquered by Tambralinga's king Sujita in the mid-9th century, the invasion by Angkor from the east, as well as the Pagan invasion of Menam Valley around the mid-11th century. All of these are probably the causes of the decline of the initial states in this area. The region, as well as Junk Ceylon and Tambralinga, were once raid by the Mau Shans from Shan States in his Indo-China raid campaign between 1220 and 1230.The Xian of Ayodhya, in the era before modern engineering, built the city at the center of the lower Chao Phraya deltaic plain, which was a floodplain that turned the city of Ayodhya into "islands in the middle of a sea" during the monsoon season. The Chinese court included Xian on a list of "maritime" kingdoms from which it demanded submission.
Early perception
Prince Damrong, who constructed a unilinear system of Thai history that was previously generally acknowledged in school textbooks, proposed in 1914 that the history of Thais in Siam proper began with establishing the Sukhothai Kingdom in 1238. This first Siamese kingdom was succeeded by Ayutthaya, Thonburi, and Rattanakosin. His works were eventually translated and edited in 1924 by Cœdès, who made this theory proliferated through his influential writings, such as The Indianized States of Southeast Asia. However, the equation that Xian was long-believed Sukhothai was contested in 1989 by Tatsuro Yamamoto, who proposes that the term "Xian 暹" found in Dade Nanhai-zhi during the era of the Yuan Dynasty was probably another polity politically superior to Sukhothai. Several modern studies also declined the theory that Sukhothai was the first independent Siam polity.Khmer, Cham, Pagan records and others
The term Siam, whose origin remains disputed, first occurs as syam in Funan–Chenla inscriptions of the 7th century. It is probably a toponym referring to some location in the lower Chao Phraya Basin. In surviving inscriptions of this period, syam occurs four times to designate female slaves, K127, K154, and K904 ) and once to identify a landlord-official, who donates rice fields to a temple. In one case syam occurs in a list where the preceding entry has the word vrau in the same sentence position. The term vrau has been considered the name of an ethnolinguistic minority group, possibly ancestors of the modem Bru or Brau people. Therefore, syam may have similarly functioned at that time, perhaps as a toponym that could also be used to refer to people of the area.Siam later occurs in slave lists on inscriptions of the Champa and Khmer kingdoms, dated in the 11th and 12th centuries. From about the same period there is also a well-known bas relief panel of Angkor Wat showing mercenaries of the Khmer army, who are identified as syam-kuk, perhaps "of the land of Siam." One cannot be certain what ethnolinguistic group these mercenaries belonged to, but many scholars have thought them to be Siam people. At about the same time in Pagan to the west syam occurs over twenty times in Old Mon and Burmese inscriptions. One syam reference is to Saṁbyaṅ an Old Mon title for a high government official, but the term mainly occurs in lists of temple slaves, both male and female. Some Syaṁ are identified by occupation, such as dancers, weavers, or carpenters.
There was a record of Siamese led by Passara, son of the king of Siam, settled in Java and established the city of Passaraan in 800 CE after they failed to sail to Makassar on Sulawesi due to the storm. Finally, it is noteworthy that several toponyms attested in 6th-century Dvaravati-period inscriptions discovered at Nakhon Pathom—most notably Śrīyānaṁdimiriṅga and Śrīyānaṁdimiriṅgapratipura—have been observed to bear a phonetic resemblance to "syam".
Chinese records
As Xiān: 13th–14th century
Xiān was first mentioned in Chinese record Yuán Shǐ 元史 in 1278 when Yuan dynasty sent He Zi-zhi 何子志, a commander with 10,000 households, as an emissary to Xian but they were detained by Champa. Xiān was on the list of the entities that Kublai Khan prepared to conquer, together with Lavo and several kingdoms on the Malay peninsular, Sumatra, South India, and Ceylon after his final conquest of China in 1279.Ten years later, the first tribute sent to China by Xian was mentioned in 1292. The Chinese court dispatched emissaries to persuade Xian to submit the following year, but Xian refused. It is recorded that an imperial order was issued again to summon and persuade the king of Xian in 1294.
Due to such a persistent persuasion, the king of Xian named Gan-mu-ding from personally appeared at the Chinese court to present the tribute with a golden plate in 1295. The tribute was sent from Xian again the following year. In 1297, emissaries from Xian, Luó hú, and Jambi were recorded. In 1299, both Xian and Sù gǔ chí sent tribute to China. These last two records indicate that Xian is not Sukhothai and the polities in the Chao Phraya River basin at that time consisted of at least 3 polities, including Lavo, Sukhothai, and Xian.
In 1304, the Dade Nanhai-zhi 大德南海志 mentions that Sù gū dǐ rely on Xian: "Xian controlled Sù gū dǐ, which is located upstream.". This makes Tatsuro assume that Sukhothai was controlled by Xian. However, a Thai academic, Keatkhamjorn Meekanon, proposes that Sukhothai may have had to use Xian to export. Xian additionally sent tribute to China in April and July 1314, 1319, and the last one in 1323. As described in Daoyi Zhilüe, the export items of Xian included sappanwood, tin, chaulmoorgra, ivory, and kingfisher feathers.
Xian appearing in Chinese dynastic history is found in the biography of Chen-yi-zhong in the Sung-shi. It reads, "In the 19th year of the Zhi-yuan 至元 era the Great Army attacked Champa and Yi-zhong fled to Xian, where he died eventually." Chen-yi-zhong was a defeated minister of the Southern Sung Dynasty who tried unsuccessfully to find a haven in Champa, which was eventually invaded by the Yuan army. Chen's subsequent flight to Xian might suggest that Xian was a commercially flourishing port in the post-Srivijayan Southeast Asian trade order, where the Southern Sung Dynasty minister could find a settlement of compatriots.
Another term San-lo 三濼 in the Lingwai Daida, written in 1178, is believed to have been an early Chinese attempt to transcribe the name of the country or the people of the upper and central Menam, which Khmer inscriptions had called Syam and which the Chinese were soon to call Xiān and Xiānluó.
In the 殊域周咨錄, written in 1583, states that when the Sui dynasty send an embassy to Chi Tu probably between 605 and 618, the kingdom was already renamed to Xian, as the quote below.
As ''Xiānluó hú/ Xiānluó'': 14th century
According to the Daoyi Zhilüe, Luó hú annexed Xiān in 1349; this was consistent with the establishment of Ayutthaya, which was said to be formed by the merging of Lavo and Siam's Suphan Buri. The new polity was recorded by the Chinese as Xiānluó hú 暹羅斛 and was later shortened to Xiānluó 暹羅. This confederation performed 41 tributary missions to the Chinese court during the Hongwu era, 33 in the name of Xiānluó hú and as Xiānluó for the remaining.Đại Việt records
During the 1334–1336 Trần dynasty invasion of, Xiān and other countries paid tribute to Đại Việt, as mentioned in the Khâm định Việt sử Thông giám cương mục Volume 9. In another Vietnamese chronicle, Đại Việt sử ký toàn thư, Xiān is also mentioned during the Lý dynasty and Trần dynasty periods, as follows:| Year | Reign | Original text | Key Points |
| 1149 | Lý Anh Tông | 己巳十年〈宋紹興十九年〉春二月, 爪哇、路貉、暹羅三國商舶入海東, 乞居住販賣, 乃於海島等處立庄, 名雲屯, 買賣寳貨, 上進方物. | Merchants from the Xiān Kingdom and others arrived at Hǎidōng and requested permission to trade and set up a trading post at Yún tún. |
| 1182 | Lý Cao Tông | 暹羅國來貢. | Xiān came to pay tribute. |
| 1241 | Lý Cao Tông | 暹羅、三佛齊等國商人入雲屯鎮, 進寳物, 乞行買賣. | Merchants from Xiān, Srivijaya, and others came to Yún tún to buy goods and request permission for trade. |
| 1313 | 時占城被暹人侵掠, 帝以天覷經畧乂安、臨平徃救.後凣西邉籌畫, 明宗悉以委之. | Xiān people attacked and raid the Champa Kingdom. The emperor sent an army to help Champa. | |
| 1360 | Trần Dụ Tông | 冬十月, 路鶴、茶哇哇音鴉、暹羅等國商舶至雲屯販賣, 進諸異物. | Xiān merchants arrived at Yún tún for trading. |
;Note
People
Xian or Siam people are described as maritime-oriented groups as said in the Chinese Daoyi Zhilüe, which conforms to the record of a Chinese Ma Huan who visited Ayutthaya in 1421/22 that says the people of Ayutthya like to practise fighting on water, and their king constantly despatches his commanders to subject neighbouring countries.At the end of the 13th century, an emerging Xian seems to have started a southward advance to the cost of the Malay peninsular. The well-known Chinese imperial admonition issued in the year 1295 well reflects such a move, reading "do not harm Ma-li-yü-êrh. The maritime Xian also attacked Samudera Pasai Sultanate on Sumatra probably between 1299–1310, but failed. The troops might have been launched by the southernmost Xian of Nakhon Si Thammarat Kingdom with either Takua Thalang or Trang or Syburi/Kedah as the navy bases. Xian also raided Champa in 1313.
In The Customs of Cambodia written by Zhou Daguan, who visited Zhenla as part of an official diplomatic delegation during 1296–1297, also referred to Siam people as:
The people in the early Xian proper—based on inscriptions dated to the Dvaravati period, found in the area together with the existing Dvaravati evidence—were probably the Buddhist Mon. The migration of the Tai-speaking people from the north to the Chao Phraya River basin happened around the 9th century. It was speculated that the trade interaction between the polities as well as the intermarriage caused a language assimilation among the people in this area.
Political entities
According to the Chinese records, the early Xian or Siam probably consisted of at least two main polities, including Phip Phli, which sent emissaries to the Yuan dynasty during the late 13th century to the early 14th century, and Su-men-bang, which later joined Lavo in the Ayutthaya Kingdom formation. Ligor became Siam proper after the preceding Tambralinga fall due to the losses in the 1247–70 wars in Sri Lanka, the 1268–69 invasion of the Javanese Singhasari, and the 1270 plague. It was revived by the Siam people from Phip Phli and evolved to the Nakhon Si Thammarat Kingdom.Although archaeological studies specify that the region was once a vibrant trading spot controlling long-distance maritime trade between the Indian Ocean and the South China Sea since the beginning of the 1st millennium, the historical records about them were rarely found, and most of the existing evidence is local legends. The ancient entities mentioned in the Chinese records potentially located in the region are the five cities of Tun Sun and its northern neighbor Chin Lin. This is most likely owing to the change in maritime trade routes, which no longer need to cross the Kra Isthmus as before 500 C.E., as well as the degradation of paper, which is more favored as a recording material in the Buddhist-dominated area.
