History of West Bengal

Ayodha Hills

The time from West Bengal's first inhabitation until the Old Stone Age, or Palaeolithic era.[9][10][11][12] Palaeolithic sites are mostly found in the upper Gandeshwari, Middle Dwarakeswar, Upper Kangsabati, Upper Tarafeni and Middle Subarnarekha valleys between 87°10' E and 22°30' N - 23°30' N. The extensive forest-covered high land and moderate rainfall of the southwestern part of West Bengal provided ideal conditions for the growth and development of the Paleolithic culture. Evidence of 42,000 years old human habitation has been found in West Bengal.[10] These human settlements have been discovered at Kana and Mahadebbera at the foothills of the Ajodhya Hills.[1][2][3] Microlithic tools found at Kana are 42,000 years old, while microlithic tools found at Mahadevera are 34,000 to 25,000 years old.[2][3] Hatpara on the west bank of Bhagirathi River has evidence of human settlements dating back to around 15,000-20,000 years.[13] About 200 small stone weapons[13] have been found here. Grains and fish bones were also found here. According to archaeologists, the prehistoric civilization of Hatpara was spread along the banks of the Bhagirathi from Ganakar to Mahipala. Fish was a common part of the human diet of the time, and coppery color of the fish bones found at the site indicates that the Burnt fish was eaten.[14]

The western plateau and delta region or the present flood plain area are the two biological regions of West Bengal where Mesolithic sites identified. The microlithic industry of West Bengal was mostly a non-geometric industry. Blades, points, scrapers, lunettes, burins, borers, flakes, and cores are the most common tools used throughout this period. Evidence from this period is scarce.[10][9]

The Neolithic culture took place in five major river valleys, namely Ajay-Mayurakshi river valley, Dwarakeswar-Damodar river valley, Gandheswari river valley, Tarafeni river valley and Subarnarekha river valley. Also a Neolithic culture developed in Kalimpong. The main tool types recovered from the site include celts (both axes and adzes), wedges, chisels, perforated tools and pounders, along with microliths and bone tools.[15][10]

A number of geopolitical divisions are observed in ancient Bengal, some of which were located in the territory of modern West Bengal. The regions of geopolitical division have expanded and receded over the centuries. The geopolitical divisions established in the territory of West Bengal were Pundravardhana, Vanga, Suhma and Radha. The western part of Pundravardhan belonged to the modern-day Malda division, and The western part of Vanga belonged to the modern-day Presidency division and Medinipur division of West Bengal. The whole of Suhma belonged to the modern-day Burdwan division, Medinipur division and Presidency division, and Radha was probably situated in modern-day West Bengal.

During the Iron Age of Bengal, West Bengal was under the Magadha-centric empires. Greek accounts mention the contemporary Gangaridai of Bengal separately, located in modern-day West Bengal and Bangladesh, although indicating that the two were ruled by common sovereigns. Historian Hem Chandra Raychaudhuri theorizes that the Nandas exercised centralized control over their core territories in present-day Bihar and Uttar Pradesh, but allowed considerable autonomy in the frontier parts of their empire.[23]

Bangarh on the bank of the Punarbhaba, about 400 km from Kolkata, have evidence of the early history of West Bengal from the Maurya period to the Pala period. Iron Age of West Bengal artefacts have been discovered here, which belong to the Pre-Maurya, Maurya and Sunga periods.[24][25] West Bengal provided sea routes to each of the Magadha empires. The empires conducted sea trade with foreign countries through the Tamralipta sea port, which was located near the modern-day Tamluk city. According to Darian, with the rise of the Maurya Empire, Tamralipti gained universal popularity as the main port of the entire basin. Ships from Ceylon, Southeast Asia, West India and the Middle East used to come to this port.[6] Chandraketugarh was another port city, situated on the banks of the Bidyadhari River.[26] Mauryan and Sunga period artifacts have been found here. Terracotta statues and chariots have been found.[27][28]
