Nabiganj Upazila: History
After the Conquest of Sylhet in 1303, many disciples of Shah Jalal migrated and settled in present-day Nabiganj where they preached Islam to the local people. Shah Sikandar migrated to Paschimgaon (Sikandarpur), Hafiz Muhammad Zakariyyah Arabi to Pithua, Shah Sadruddin Qurayshi to Parbatpur (Sadrabad) and Qazi Tajuddin Qurayshi to Chouki.
In the late 17th century, Inathganj Bazar was founded. Inathganj became a centre for the Asian Jute trade. The current Inathganj High School was originally a jute warehouse. Many ships would crowd in the banks of Inathganj Bazar, and go to many corners of the world, and evidence of this remains at the present-day high school.
