Kakabhadra

Kakabhadra (กากะพัตร), also referred to as Sakkorn Dam (สักกรดำ) in the Northern Chronicle,^{[2]: 3 [3]: 14} was the ruler of Takkasila (ตักศิลา), identified with Nakhon Pathom in Kamalanka. He is traditionally credited with the establishment of the Chula Sakarat era in 638 CE, an event of enduring historical significance.^[2]: 4

According to the chronicle, Manit Vallibhotama (มานิต วัลลิโภดม) dated the enthronement of Kakabhadra’s successor, Kalavarnadisharaja, to 641 CE.^[3]: 12 From this calculation, Kakabhadra’s reign is estimated to have commenced around 569 CE, as the text attributes to him a rule of 72 years over Takkasila.^[2]: 3 Because this period coincides with that associated with Siddhijaya Brahmadeva, some scholars have argued that Kakabhadra and Siddhijaya may in fact represent the same monarch.^[1]: 4 Nevertheless, the accounts provide sufficient grounds for distinguishing them as separate figures.^[a]

Kakabhadra’s reign unfolded during a period of recurrent conflict between Tou Yuan, situated to the southeast, and Chenla in the Tonlé Sap Basin.^[4] By 647, however, Tou Yuan is recorded as a vassal of Dvaravati Kamalanka and,^{[5]: 269 [6]: 15–16} in the following year, was reorganized as the Lavo Kingdom under the authority of Kakabhadra’s elder son, Kalavarnadisharaja.^{[3]: 11–2 [1]: 3–4} Although there is no evidence that Dvaravati directly intervened in these hostilities, but the conflict between Chenla and Dvaravati is preserved in the Bhavavarman II Inscription (K.1150), also known as the Inscription of Wat Kud Tae, dating 6th century, the text which is in Sanskrit with Pallava script, says that during the Chenla's northwest expansion, the minister who was the deputy governor of Shrestapura engaged in the wars against Sambuka,^{[7]: 24–25, 30 [8]} which has been identified with modern Nakhon Pathom.^{[7]: 24–25, 30} Japanese scholar Hoshino has suggested that several polities within the Menam and Mekong Basins may have been drawn into the wider conflicts,^{[9]: 54–5} which possibly extended into the wars between Lavo and Haripuñjaya in the early 10th century.^{[9]: 36–7}

During the Sui period (581–618 CE), Dvaravati was documented in the Tongdian as the Tou-he Kingdom,^[10]: 133 a polity distinguished by its urban and administrative sophistication. Its principal city accommodated over 10,000 inhabitants, and the royal palace, guarded by approximately 100 soldiers, reflected the centralization of authority and ceremonial grandeur, with the monarch’s regalia—comprising crown, attire, and ornaments—crafted from gold and embellished with precious gemstones. The kingdom’s governance was organized hierarchically under the Chao-qing-jiang-jun, who exercised overarching administrative control, while subordinate officials, including the Can-jun, Gong-cao, Sheng-bo, Cheng-ju, Jin-wei-jiang-jun, Zan-li, and Zan-fu, managed military operations and internal affairs. Legal structures were codified, with execution prescribed as the most severe penalty, indicating a formalized judicial system.^{[10]: 130–1}

Economically, the city (or country) featured six markets (or trading hub cities, potentially Nakhon Pathom, Khu Bua, Uthong, Si Mahosot, Dong Lakhon, and Pong Tuk), and the kingdom did not impose personal taxation.^{[10]: 221–3} The people, largely engaged in agriculture, were noted for their proficiency in riding both horses and elephants, a skill that underscored their adaptability in mobility and warfare. Buddhism constituted the principal religious practice, and the existence of educational institutions attests to the kingdom’s commitment to intellectual cultivation. Linguistically, the vernacular employed within the kingdom diverged from Chinese, further illustrating the distinct cultural and administrative identity of Dvaravati within the regional milieu.^{[10]: 131–2}
