About Cooch Behar District
Cooch Behar formed part of the Kamarupa Kingdom of Assam from the 4th to the 12th centuries. In the 12th century, the area became a part of the Kamata Kingdom, first ruled by the Khen dynasty from their capital at Kamatapur. The Khens were an indigenous tribe, and they ruled till about 1498 CE, when they fell to Alauddin Hussain Shah, the independent Pathan Sultan of Gour. The new invaders fought with the local Bhuyan chieftains and the Ahom king Suhungmung and lost control of the region. During this time, the Koch tribe became very powerful and proclaimed itself Kamateshwar (Lord of Kamata) and established the Koch dynasty.
The first important Koch ruler was Biswa Singha, who came to power in 1510 or 1530 CE. Under his son, Nara Narayan, the Kamata Kingdom reached its zenith. Nara Narayans younger brother, Shukladhwaj (Chilarai), was a noted military general who undertook expeditions to expand the kingdom. He became governor of its eastern portion.
After Chilarais death, his son Raghudev became governor of this portion. Since Nara Narayan did not have a son, Raghudev was seen as the heir apparent. However, a late child of Nara Narayan removed Raghudevs claim to the throne. To placate him, Nara Narayan had to anoint Raghudev as a vassal chief of the portion of the kingdom east of the Sankosh river. This area came to be known as Koch Hajo. After the death of Nara Narayan in 1584, Raghudev declared independence. The kingdom ruled by the son of Nara Narayan, Lakshmi Narayan, came to be known as Cooch Behar. The division of the Kamata Kingdom into Koch Behar and Koch Hajo was permanent. Koch Behar aligned itself with the Mughal Empire and finally joined the India as a part of the West Bengal, whereas remnants of the Koch Hajo rulers aligned themselves with the Ahom kingdom and the region became a part of Assam.
As the early capital of the Koch Kingdom, Cooch Behars location was not static and became stable only when shifted to Cooch Behar town. Maharaja Rup Narayan, on the advice of an unknown saint, transferred the capital from Attharokotha to Guriahati (now called Cooch Behar town) on the banks of the Torsa river between 1693 and 1714. After this, the capital was always in or near its present location.
In 1661 CE, Maharaja Pran Narayan planned to expand his kingdom. However, Mir Jumla, the subedar of Bengal under the Mughal emperor Aurangazeb, attacked Cooch Behar and conquered the territory, meeting almost no resistance. The town of Cooch Behar was subsequently named Alamgirnagar.Maharaja Pran Narayan regained his kingdom within a few days.
