Samatata

Samataṭa (Brahmi script: sa-ma-ta-ṭa) was an ancient geopolitical division of Bengal in the eastern Indian subcontinent. The Greco-Roman account of Sounagoura is linked to the kingdom of Samatata. Its territory corresponded to much of present-day eastern and southern Bangladesh (particularly Dhaka division, Barisal division, Sylhet Division, Khulna Division and Chittagong Division). The area covers the trans-Meghna part of the Bengal delta. It was a center of Buddhist civilisation before the resurgence of Hinduism, and Muslim conquest in the region.

Archaeological evidence in the Wari-Bateshwar ruins, particularly punch-marked coins, indicate that Samataṭa was probably a province of the Mauryan Empire. The region attained a distinct Buddhist identity following the collapse of Mauryan rule. The Allahabad pillar inscriptions of the Indian emperor Samudragupta is the earliest reference of Samataṭa in which it is described as a tributary state.

Samataṭa gained prominence as an important region of Bengal during the reigns of the Gauda Kingdom, Khadga dynasty, First Deva dynasty, Chandra dynasty and Varman dynasty between the 6th and 11th centuries. During this period, the rulers of Samataṭa also reigned over parts of Arakan, Tripura and Kamarupa. Chinese travellers provide an elaborate description of the region in the 7th century. According to Alexander Cunningham, Jessore was the capital of Samatata. Xuanzang of China visited the region in 630s.

Records of the Sena dynasty include mention of Samataṭa as a haven for Sena kings who escaped the Muslim conquest of western Bengal during the 13th century. The area was eventually absorbed by the forces of the Delhi Sultanate.

Samataṭa has been described by various similar names, including Samatat/Samata/Saknat/Sankat/Sankanat.In Sanskrit, sama means equal and taṭa means coast or shore.

On the basis of the evidence provided by inscriptions, Chinese writings, and archaeological evidence, it can be deduced that Samatata covered the trans-Meghna territories. It included areas along the banks of the Meghna River and its tributaries; including the modern Bangladeshi districts of Sylhet, Maulvi Bazar, Habiganj, Sunamganj, Narsingdi, Narayanganj, Dhaka, Munshiganj, Brahmanbaria, Chandpur, Comilla, Noakhali, Feni and Lakshmipur. It included the Bangladeshi Channel Islands of Hatia and Sandwip; as well as the islands of Bhola, Maheshkhali, Kutubdia and St. Martin's.^{[citation needed]} It included parts of Tripura (in present-day Northeast India), Bangladesh's Chittagong and Cox's Bazar districts; and northern Arakan (present-day Rakhine State, Myanmar). Samatata's erstwhile neighbours included the geopolitical divisions of Vanga (Southwest Bengal), Pundravardhana (North Bengal), and parts of Kamarupa (historical Assam).

The Roman geographer Ptolemy wrote about a trading post called Souanagoura in the eastern part of the Ganges-Brahmaputra delta. The archaeologist Sufi Mostafizur Rahman believes the riverside citadel in the Wari-Bateshwar ruins was the city-state of Sounagoura. According to Ptolemy, Sounagoura was located on the bank of the Brahmaputra River and was an "emporium", which is a term used by the Roman Empire to refer to a trading colony set up by Roman merchants. The Brahmaputra River flowed down from the Himalayas and to the east of Wari-Bateshwar before joining the Meghna River on its way to the Bay of Bengal. Ptolemy's account places Sounagoura near the old course of the Brahmaputra River. The Brahmaputra changed its course following an earthquake in 1783. Excavations in Wari-Bateshwar reveal an urban and monetary civilisation since the pre-Mauryan period. Archaeologist and historian Dilip Kumar Chakrabarti also considers Wari-Bateshwar to be a part of the trans-Meghna region. In a book edited by Patrick Olivelle, Chakrabarti states "It appears that Wari-Bateshwar belongs to the Samatata tract. Till now this is the only early historic site reported from this tract, but the very fact that it existed as early as the mid-fifth century BCE in this part of Bangladesh shows the geographical unit of Samatata, although inscriptionally documented in the fourth century CE, has a much earlier antiquity which touches the Mahajanapada period. Secondly, on the basis of the fact that Wari-Bateshwar is a fortified settlement, we argue that in addition to its character as a manufacturing and trading center, it was also an administrative center and most likely to be the ancient capital of the Samatata region".

Soon after the death of emperor Ashoka, the Mauryan Empire declined and the eastern part of Bengal became the state of Samatata. The rulers of the erstwhile state remain unknown. During the Gupta Empire, the Indian emperor Samudragupta recorded Samatata as a "frontier kingdom" which paid an annual tribute. This was recorded by Samudragupta's inscription on the Allahabad pillar, which states the following in lines 22–23.
