Also known as Greater Sylhet or Sylhet region is the northeastern division of Bangladesh, named after its main city, Sylhet. It is bordered by the Meghalaya, Assam and Tripura states of India to the north, east and south, respectively; and by the Bangladesh divisions of Chittagong to the southwest and Dhaka to the west. In 1995, Sylhet was declared the 6th division of Bangladesh. Prior to that, it was part of the Chittagong Division. The Sylhet Division is subdivided into four Districts: Habiganj, Moulavibazar, Sunamganj and Sylhet. Further, the Sylhet Division contains 35 sub-districts (upazila/thana), 323 union parishad, 10,185 villages and 14 municipalities. Population: approximately 10 million, which is less than 7% of the total population of Bangladesh.
Sylhet is considered one of the most picturesque and archaeologically rich regions in South Asia, and has major Islamic Sufi shrines and Hindu holy sites. Its bourgeoning economy has contributed to the regional attractions of landscapes filled with fragrant orange and pineapple gardens and tea plantations. Many Sylheti community members are working and residing abroad, particularly in the United Kingdom. They send remittances to fund projects and industries within the Sylhet Division, which have led to the expansion of the export industry and foreign investment sectors.
The name Sunamganj is derived from its founder, Sipahi Sunamuddin, who established a bazaar on the bank of the river Surma. Sunamganj is renowned for bards and folk music.
Sunamganj is located in north-eastern Bangladesh in the Sylhet Division with the Sylhet District to its east, Habiganj District to its south and Netrokona District to its west. The Surma River and Kushiyara River run through the district whilst Ratna River crisscrosses the district and beyond. The River Da'uka or Danuka also run through district Sunamganj.
The annual average temperature of Sunamganj has a maximum of 33.2 °C and a minimum 13.6 °C, with annual rainfall of 3334 mm. There are many haors and beels (wetlands ecosystems) in Sunamganj. Sunamganj District was underwater in ancient time; it was part of a vast sea by the name of Ratnag, which was an abbreviation of Ratnakar (common noun for sea in Bengali: রত্নাকর). Ratnakar expanded from cliffs of Meghalaya on the west to the coast of Tripura in the east, both Meghalaya and Tripura were inhabited by Kirata people of Mongoloid race. People from Meghalaya travelled to Tripura and vice versa by seagoing vessels. Seabed began to rise by the end of twelfth century due to alluvial silting over the centuries. It was northeast of the district that first began to elevate in form of atolls and then most parts of the district arose from underneath the sea.
Sunamganj has a total population of 1,968,669; males constitute 50.89% and females 49.11%. People of Sunamganj are racially and ethnically diverse. Since 1960 sunamganj has been known for the stone and sand business. Sunamganj has more haors than any other district in Bangladesh and this makes it famous for fishery business. Information and Communications Technology (ICT) industry is relatively a new sector in the country's economy. Though, it is yet to make tangible contributions in the national economy.
Sunamganj District comprises 11 sub-districts or Upazilas: Bishwamvarpur, Chhatak, Derai, Dharamapasha, Dowarabazar, Jagannathpur, Jamalganj, Sullah, Sunamganj Sadar, Dokkin Sunamganj, and Tahirpur.
Nidhiram was the primogenitor of the Gourarang Jaminder(landlord) family. He was the son from a Kayasth Family (Kayasth are considered to be members of the scribe caste in Hindu Religion). He was sent to Sylhet (previously known as Srihatya) for most probably treasury work with a promotion too. There he married a beautiful daughter of a landlord and ended up living there in a high forest land on the east side of Surma River which he got as a gift from a prince. Since then his generations expanded in this country.
