Dvaravati

Dvaravati was an ancient Mon political principality from the 6th century to the 11th century, located in the region now known as central Thailand,   and was speculated to be a succeeding state of Lang-chia or Lang-ya-hsiu (หลังยะสิ่ว). It was described by Chinese pilgrims in the middle of the 7th century as a Buddhist kingdom named To-lo-po-ti situated to the west of Isanapura (Cambodia), to the east of Sri Ksetra (Burma),  and adjoined Pan Pan in the South. Its northern border met Chia-lo-she-fo, which was speculated to be either Kalasapura, situated along the coast of the Bay of Bengal somewhere between Tavoy and Rangoon, or Canasapura in modern northeast Thailand. Dvaravati sent the first embassy to the Chinese court in around 605–616.

Dvaravati also refers to a culture, an art style, and a disparate conglomeration of principalities of Mon people. Archaeological research over the past two decades or so has revealed the presence of a "Proto-Dvaravati" period which spans the 4th to 5th centuries, and perhaps earlier.

Dvaravati lost its importance after the rise of the Angkor in the lower Mekong basin around the 11th–13th centuries. In the 14th century, one of its main principalities, Si Thep, was almost left abandoned, while the remaining was split into the city-state confederation of Suphannabhumi in the west and the Lavo Kingdom in the east.

However, a new kingdom, Ayutthaya, was subsequently founded southward on the bank of the Chao Phraya River in 1351, as the succeeded state, as its capital's full name referred to the Kingdom of Dvaravati; Krung Thep Dvaravati Si Ayutthaya (กรุงเทพทวารวดีศรีอยุธยา). All former Dvaravati principalities, Lavo, the northern cities of the Sukhothai Kingdom, and Suphannabhumi, was later incorporated to the Ayutthaya Kingdom in 1388, 1438, and the mid-15 century, respectively.

According to an inscription on a bronze gun acquired by the Burmese in 1767, when Ayuthia, Siam's capital at the time, fell to an invading Burmese force, the Burmese still referred to Ayutthaya as Dvaravati. Several genetic studies published in the 2020s also founded the relations between the Mon people and Siamese people (Central Thai people) who were the descendants of the Ayutthaya.

History
The culture of Dvaravati was based around moated cities, the earliest of which appears to be U Thong in what is now Suphan Buri Province. Other key sites include Nakhon Pathom, Phong Tuk, Si Thep, Khu Bua and Si Mahosot, amongst others. Legends engraved on royal urns report the following kings: Suryavikrama (673-688), Harivikrama (688-695), Sihavikrama (695-718). A Khmer inscription dated 937 documents a line of princes of Canasapura started by a Bhagadatta and ended by a Sundaravarman and his sons Narapatisimhavarman and Mangalavarman. But at that time, the 12th century, Dvaravati began to come under constant attacks and aggressions of the Khmer Empire and central Southeast Asia was ultimately invaded by King Suryavarman II in the first half of the 12th century. Hariphunchai survived its southern progenitors until the late 13th century, when it was incorporated into Lan Na.

The term Dvaravati derives from coins which were inscribed in Sanskrit śrī dvāravatī. The Sanskrit word dvāravatī literally means "that which has gates".

The traditional chronology of Dvaravati is mainly based on the Chinese textual account and stylistic comparison by art historians. However, the results from excavations in Chan Sen and Tha Muang mound at U-Thong raise questions about the traditional dating. Newly dated typical Dvaravati cultural items from the site of U-Thong indicate that the starting point of the tradition of Dvaravati culture possibly dates as far back as 200 CE. Archaeological, art historical, and epigraphic (inscriptions) evidence all indicate, however, that the main period of Dvaravati spanned the seventh to ninth centuries. Dvaravati culture and influence also spread into Isan and parts of lowland Laos from the sixth century onward. Key sites include Mueang Fa Daet in Kalasin Province, Mueang Sema in Nakhon Ratchasima Province, and many others.

Government
Little is known about the administration of Dvaravati. It might simply have been a loose gathering of chiefdoms rather than a centralised state, expanding from the coastal area of the upper peninsula to the riverine region of Chao Phraya River. Hinduism and Buddhism were significant. The three largest settlements appear to have been at Nakhon Pathom, Suphanburi, and Praak Sriracha, with additional centers at U Thong, Chansen, Khu Bua, Pong Tuk, Mueang Phra Rot, Lopburi, Si Mahosot, Kamphaeng Saen, Dong Lakhon, U-Taphao, Ban Khu Mueang, and Si Thep.

Rulers
The excavation in several sites found silver coins dated the 7th century that mentioned the king and queen of the kingdom written in Sanskrit with Pallava script: śrīdvaravatīsvarapunya (King Sridvaravati, who has great merit) and śrīdvaravatīsvaradevīpuṇya (the goddess of the meritorious King Dvaravati). In addition, the copper plate dating from the 6th–mid 7th centuries found at U Thong also mentions King Harshavarman (หรรษวรมัน), who was assumed by Jean Boisselier to be one of the kings of Dvaravati, while George Cœdès considered the plate was brought from the Khmer Empire, and the name mentioned might be the Khmer king as well. However, the periods seem unrelated since King Harshavarman I of Khmer reigned from 910–923, 200 years later than the age of the inscription, and Harshavarman I's grandfather was Indravarman I,  not Isanavarman as the inscription mentioned.

Moreover, the inscription found in Ban Wang Pai, Phetchabun province (K. 978), dated 550 CE, also mentions the enthronement of the Dvaravati ruler, who was also a son of Prathivindravarman, father of Bhavavarman I of Chenla, which shows the royal lineage relation between Dvaravati and Chenla. However, the name of such a king was missing. The other king was mentioned in the Nern Phra Ngam inscription, found in Nakhon Pathom province, dated mid 5th – mid 6th centuries CE but the name was missing as well.

The following is a list of rulers of Dvaravati.

Art
Dvaravati itself was heavily influenced by Indian culture, and played an important role in introducing Buddhism and particularly Buddhist art to the region. Stucco motifs on the religious monuments include garudas, makaras, and Nāgas. Additionally, groups of musicians have been portrayed with their instruments, prisoners, females with their attendants, soldiers indicative of social life. Votive tablets have also been found, also moulds for tin amulets, pottery, terracotta trays, and a bronze chandelier, earrings, bells and cymbals.
