Sri Dharmasokaraja I

Sri Dharmasokaraja I , , also known by the alternative names Narapati , was a 12th-century monarch of mainland and peninsular Southeast Asia, known primarily from epigraphic and legendary sources. He is mentioned in the Dong Mè Nang Mưo’ng Inscription (K. 766), written in Pali and Old Khmer, as well as in later Thai chronicles, notably the and the Legend of Phatthalung . He is traditionally credited with the refoundation of Nakhon Si Thammarat in 1077 and the establishment of a dynastic line that produced two successors bearing the same regnal title.

The reign of Sri Dharmasokaraja I at Tambralinga, followed by those of his successors—Sri Dharmasokaraja II and Sri Dharmasokaraja III—was probably a period of Pagan suzerainty over Tambralinga, extending from the mid-11th century, after the Chola invasion in 1025/26, to the early 13th century,

Historical attestation and political role

Sri Dharmasokaraja I is first attested in the Dong Mè Nang Mưo’ng Inscription (K. 766), dated to 1167/68 CE, which refers to two monarchs sharing the same regnal title, explicitly stating that the earlier ruler had already died by the time of its composition. While plausible, this interpretation remains conjectural due to the absence of direct epigraphic corroboration.

An alternative tradition is preserved in another recension of the Legend of Nakhon Si Thammarat, which asserts that Sri Dharmasokaraja I originated from Hanthawaddy and subsequently re-founded Nakhon Si Thammarat. When this tradition is examined within its broader geopolitical context, such an origin appears plausible. During the relevant period, Hanthawaddy was under the authority of the Pagan Kingdom, which expanded its influence southward to Tambralinga and is recorded in the Northern Chronicle as having launched incursions into the Menam Basin during the 11th to 12th centuries. Lavo, during the reign of Chandrachota (r. 1052–1069), is likewise recorded to have fallen under Pagan influence. This Hanthawaddy origin theory accords with the broader interpretations advanced by Gordon Luce and D.K. Wyatt, both of whom proposed that Tambralinga was under Pagan domination during the late 11th and 12th centuries, with Luce suggesting a period spanning approximately 1060–1200 The Northern Chronicle further records an invasion of Ayodhya in 1087, during the reign of Narai I, who successfully repelled the attack but died later that same year. Thereafter, Ayodhya entered a two-year period of internal power struggle, culminating in the accession of a noble of uncertain dynastic origin known as Phra Chao Luang. This second phase of expansion corresponds closely with the period in which Sri Dharmasokaraja I is attested in the Menam Basin, where his authority is recorded to have ended due to a severe epidemic in 1117. It also significantly reshapes the pre-Sukhothai historical narrative, particularly traditions stating that Sukhothai had formerly existed as a tributary polity under Indapraṣṭhanagara. It was during this phase that Sri Dharmasokaraja I’s son appears as one of the rulers exercising power in the region.

Legendary traditions and debates on origin

According to the Legend of Nakhon Si Thammarat, Sri Dharmasokaraja I originally ruled at Indaprasthanagara, but was forced to abandon the city due to a severe epidemic that caused economic collapse and population decline. He subsequently migrated southward and re-founded Nakhon Si Thammarat, which was devastated by a Chola invasion from Lanka in 1030 CE and probably became under Pagan control around the late 11th to early 12th century. Through his patronage of Buddhism, he is said to have maintained cordial religious relations with Lanka.

Some versions of the legend further assert that Sri Dharmasokaraja I and his younger brother, named Mala, originated from India. If accepted, this narrative would imply a south-to-north expansion of political influence into the Chao Phraya basin, including Lavo and Dong Mae Nang Mueang. However, this Indian-origin hypothesis is generally regarded as weak. The multilingual character of the Dong Mè Nang Mưo’ng Inscription—composed in Pali, Khmer, and Thai, rather than Sanskrit alone—strongly suggests a local or regional origin rooted in the Lavo–Indaprasthanagara cultural milieu.

An alternative interpretation proposes that the dynasty was indigenous to Nakhon Si Thammarat, rejecting both Indian and Lavo-centric origin theories. This view draws support from phonetic considerations and the Chinese tribute records dated to 1168 CE and aligns with the Legend of Phatthalung, which states that Sri Dharmasokaraja II departed to rule another city, implying an established local dynastic base in the peninsula rather than recent foreign origins.
