Bishwanath Upazila: History
One of the palaces of Gour Govinda, the last Hindu ruler of Sylhet, was situated in present-day Bishwanath. Its ruins are still intact and is locally referred to as 'Jahazer Manzil' and next to Govinda's personal pond, the 'Satpari Dighi'. During the Muslim conquest of Sylhet in 1303, Govinda abandoned Sylhet and fled to the Kamrup region. Shah Jalal, a leader of the conquest, was known to have dispatched his disciples across the region to propagate Islamic teachings. Among the disciples that arrived in present-day Bishwanath is Syed Batauk, the ancestor of Abdul Karim Kauria. Shah Chand was the son of Shaykh Kalu, another of Shah Jalal's disciples, and the village of Chandbharang was named after him. Shah Chand is the forefather of the Chowdhuries of Chandbharang, including Suheluddin Chowdhury and Shafiqur Rahman Chowdhury.
After the defeat of Raja Subid Narayan of Ita by Khwaja Usman in the early 17th century, many Hindus migrated elsewhere including the area now comprising Bishwanath. Vijayaram Upadhayaya and his Kayastha student Bidhar Khan sailed with their family and friends through the Kapna river to this area (then a forest) for safety. The area was then home to a group of bandits led by Jula, but they were defeated by Bidhar Khan and his associates. The new settlers named the area 'Banabhag' (forest area), the area which he docked his boat came to be known as 'Bidhar Ghat' and the neighbourhood of the bandits came to be known as 'Jular Chiri'. When the Mughals came into power, they divided Banabhag into three parganas: Khalisa-Banabhag, Bazu-Banabhag and Kazakhabad. Bidhar Khan became the Zamindar of Bazu-Banabhag. His descendant, Ramnath Dhar, was a contemporary of Gopinath Bachaspati. Dhar's son, Babu Ramjivan Rai, was given the title of Chowdhury and granted land in Baurbhag by Inayetullah Khan, the Mughal administrator of Sylhet, in 1692. He was known to have been devoted to idol worship. His son, Bhavani Shankar, was the father of Zamindar Ram Shankar Chowdhury. Ram Shankar's son, Bishwanath Rai Chaudhury, established the 'Bishwanath Bazaar' which gradually expanded. His son, Brajanath Chaudhury, established an akhara for Chaitanya Mahaprabhu and was succeeded by Baikuntha Nath Chaudhury. Baikuntha Nath's son, Varada Nath Chaudhury, was a distinguished poet of Bishwanath.
Bishwanath was established as a thana in 1922. During the Bangladesh War of 1971, many Hindus were killed in Bishwanath including Jitendra Das, Dhirendra Kumar Das, Byomkesh Chaudhury, Narayan Sen and Basanta Kumar Das. Bishwanath Thana was upgraded to upazila (sub-district) in 1983 as part of President of Bangladesh, Hussain Muhammad Ershad's decentralisation programme.
