Sukhothai period Most historians identify the
Tambralinga kingdom (existing c. 10th to 13th century) as a precursor of Nakhon Si Thammarat. During the late 1st and early 2nd millennium CE,
Tai peoples expanded in mainland Southeast Asia. By the 13th century, they made Nakhon Si Thammarat one of their
mueang (city-states). The exact circumstances of the Tai taking over the earlier Buddhist and
Indianised kingdom at this location remain unclear, but it must have taken place before the mid-13th century. The
Ramkhamhaeng stele of 1283 (or 1292) lists Nakhon Si Thammarat as the southernmost tributary kingdom of Sukhothai, probably ruled by
Sri Thammasokaraj, a relative of King
Ram Khamhaeng. Nakhon Si Thammarat's Buddhist Theravada tradition was a model for the whole Sukhothai kingdom. Exemplary for the Southeast Asian
Mandala model, the dependency towards Sukhothai was only personal, not institutional. Therefore, after Ram Khaemhaeng's death, Nakhon Si Thammarat regained its independence and became the dominant Thai
mueang on the Malay Peninsula.
Ayutthaya period In the Old Javanese
Desawarnana document of 1365, the
Majapahit kingdom recognised Nakhon Si Thammarat as belonging to
Siam. The
Palatine law of King
Trailok dated 1468, listed Nakhon Si Thammarat as one of eight "great cities" (
phraya maha nakhon) belonging to the Ayutthaya kingdom. Nevertheless, it maintained its own dynasty and had vassal states of its own, which it mediated to Ayutthaya (again a typical feature of the Mandala model with its tiered levels of power). Under king
Naresuan (r. 1590–1605) it became instead a "first class province" (
mueang ek). However, the post of provincial governor was still quasi-hereditary and usually handed down from father to son within the old Nakhon Si Thammarat dynasty. It was the most important among Ayutthaya's southern provinces and enjoyed a primacy vis-à-vis the other provinces on the Malay Peninsula. Its role in overseas trade (involving Dutch and Portuguese merchants) resulted in the province's substantial wealth and contributed to a high level of confidence and claim of autonomy. During the Ayutthayan succession conflict of 1629, Nakhon Si Thammarat rebelled against the new king
Prasat Thong. The usurper sent the influential Japanese adventurer
Yamada Nagamasa with his mercenary force to quell the rebellion and made him governor and lord of Nakhon Si Thammarat for a short time. Another insurrection of Nakhon Si Thammarat against the capital took place after the
Siamese revolution of 1688 when the local ruler refused to accept the accession of usurper king
Phetracha.
Thonburi period After the
fall of Ayutthaya in 1767, Nakhon Si Thammarat again enjoyed a short period of independence, including its subordinate provinces on the Malay Peninsula, but was subdued by
Taksin in 1769 on his mission to
reunite Siam.
Rattanakosin period Under
Rama I, the rank of the Lord of Nakhon Si Thammarat was demoted from a vassal ruler to a mere governor of a first-class province and his control over the northern Malay sultanates (including
Patani) was taken away, instead awarding them to the governor of
Songkhla. Nakhon Si Thammarat was supervised by the
Kalahom (Minister of the Southern provinces). In 1821 and 1831 however, kings
Rama II and
Rama III again tasked the governor of Nakhon Si Thammarat to quell rebellions in the Malay sultanate of
Kedah. The tiered relationships between Bangkok, Nakhon Si Thammarat and the Malay sultanates of Kedah and
Perak posed a conundrum for the British
East India Company in Malaya, which incorrectly assumed the European model of exclusive sovereignty (or suzerainty) over territories.
Integration into the Siamese central state With the
Thesaphiban reform of Prince
Damrong Rajanubhab at the end of the 19th century the kingdom was finally fully absorbed into Siam. A new administrative entity named
monthon (circle) was created, each supervising several provinces.
Monthon Nakhon Si Thammarat, established in 1896, covered those areas on the east coast of the peninsula, i.e. the provinces
Songkhla,
Nakhon Si Thammarat and
Phatthalung. == Naksat cities ==
