Koch Kingdom (Cooch Behar)

Overview

Koch-Bodo kingdom founded by Biswa Singha in 1515 CE, centered on Cooch Behar (northern Bengal) and western Assam. Peak under Nara Narayan and his brother Chilarai (Karatoya to Barnadi, 1540-1581). Split along the Sankosh river in 1581 into Koch Bihar (west, Mughal tributary, became British protectorate 1773, merged with India 1949) and Koch Hajo (east, conquered by Islam Khan 1612-13, absorbed by Ahom after 1682).

Territory Phases

1. Koch Kingdom (Founding under Biswa Singha)1515 CE – 1545 CE

   Founding phase of the Koch kingdom under Biswa Singha (r. c. 1515–1540), who unified the Mech, Koch and Bhuyan chiefs of the Brahmaputra–Teesta doab after the Khen dynasty of Kamata had been destroyed by Alauddin Husain Shah of Bengal in 1498. Early fortified capital at Chikna (Chikanagrama) in the foothills of modern Kokrajhar district, later shifted to Hingulabas in the plains. Biswa Singha re-occupied the old Khen capital of Kamatapur (modern Gosanimari, Cooch Behar district) and began the Sanskritisation of the dynasty, claiming descent from Shiva.

2. Koch Kingdom (Peak under Nara Narayan & Chilarai)1540 CE – 1585 CE

   Peak of Koch power under Malladev Nara Narayan (r. c. 1540–1587) and his brother and senapati Sukladhvaj 'Chilarai'. Direct control extended from the Karatoya river in the west to the Barnadi/Bhareli in the east along the north bank of the Brahmaputra. Chilarai's campaigns (c. 1562–1568) extracted tribute from the Ahom (briefly occupying Garhgaon after forcing Sukhampha's submission in 1562–63), the Dimasa Kachari, the Jaintia, Manipur, Tripura and the Nawab of Sylhet — though these southern and eastern territories were tribute zones, not directly administered. Nara Narayan and Chilarai rebuilt the Kamakhya temple on Nilachal Hill in 1565 (Saka 1487 inscription). Srimanta Sankardeva and Madhavdev, the leaders of Assamese Neo-Vaishnavism, took refuge at the Koch court after persecution by the Ahoms; Sankardev died at Bheladonga near Cooch Behar in 1568. Chilarai himself died of smallpox in 1571 on the banks of the Ganges during a Mughal-allied campaign in Bengal.

3. Koch Bihar (Mughal Tributary Kingdom)1581 CE – 1775 CE

   Western successor kingdom after the 1581 partition, when Nara Narayan assigned the trans-Sankosh east to his nephew Raghudev as Koch Hajo and retained the west for his son Lakshmi Narayan. The partition became permanent on Nara Narayan's death in 1587. Koch Bihar comprised the wedge between the Teesta and Sankosh rivers, bounded by Bhutan in the north and Mughal Bengal (Rangpur sarkar) in the south. Lakshmi Narayan (r. 1587–1621) accepted Mughal suzerainty c. 1596–1603 in exchange for Mughal help against his cousin Raghudev. In 1661 Mir Jumla's army transited the state on the way to Assam, briefly occupying Cooch Behar town; Pran Narayan recovered the capital after Mir Jumla's 1663 retreat. The kingdom remained internally autonomous, paying tribute to the Mughal governors of Bengal and later the Nawabs of Murshidabad, and was a major patron of Gaudiya Vaishnavism and Assamese Neo-Vaishnavite mathas.

4. Koch Hajo (Eastern Successor)1581 CE – 1613 CE

   Eastern successor kingdom after the 1581 partition, ruled from the pilgrimage town of Hajo (on the Brahmaputra ~24 km northwest of Guwahati) by Raghudev (c. 1581–1603) and his son Parikshit Narayan (1603–1613). Extended from the Sankosh river east to the Barnadi/Bhareli, covering modern Goalpara, Bongaigaon, Barpeta, Nalbari, Kamrup and Darrang districts. Raghudev restored and patronised the Hayagriva Madhava temple at Hajo, which gave the kingdom its name. The kingdom was conquered by the Mughal subahdar Islam Khan Chishti in 1612–1613 after a campaign led by Mukarram Khan and Satrajit; Parikshit Narayan was besieged at Dhubri and finally at Pandu, where he surrendered. Koch Hajo was absorbed into Mughal Bengal as the sarkars of Kamrup and Dhekeri. Parikshit's brother Balinarayan took refuge with the Ahoms and served as the figurehead of a Koch rump under Ahom protection. The former Koch Hajo territory was contested between Mughals and Ahoms throughout the 17th century and was permanently transferred to Ahom control after the Battle of Itakhuli (1682), which established the Manas river as the Ahom–Mughal frontier.

5. Koch Bihar (British Protectorate Princely State)1773 CE – 1949 CE

   Koch Bihar as a British protectorate after the Anglo-Cooch Behar Treaty of 5 April 1773, signed at Fort William following the 1770–72 Bhutanese invasion that had captured Raja Dharendra Narayan. Under the treaty the state ceded sovereignty to the East India Company in exchange for military aid; the Bhutanese were expelled by April 1774. Territorially confined to a stable wedge between the Teesta and Sankosh, corresponding to the modern Cooch Behar and Alipurduar districts (West Bengal) plus slivers of Jalpaiguri and Lalmonirhat (Bangladesh). Nineteenth- and early-twentieth-century rulers — especially Nripendra Narayan (r. 1863–1911) and his successors — were notable modernisers and patrons of education, architecture (the Cooch Behar Palace built 1887) and Bengali literature. The state acceded to the Dominion of India on 28 August 1949 under Maharaja Jagaddipendra Narayan (merger agreement signed with V. P. Menon), was ceded with effect from 12 September 1949, and was administratively merged into West Bengal on 1 January 1950.
