There are no traces of 100–150 years old left in Hatiya due to the erosion of nature in the face of the heavy flooding of the Meghna and the huge body of water in the Bay of Bengal.

According to a report by an organization called Web Star, the erosion of the northern part of the original territory of Hatiyar began in 1890.

Although it is difficult to determine the exact size due to continuous demolition, according to the estimates of the Upazila Parishad, the current area of the tool is mentioned as 2100 km2.

Along with native elders, Muhammad Amin, the former magistrate of Hatiya Upazila and author of Tilottama Hatia: History and Tradition asserts that the island came to be greatly populated only after the arrival of Muslim traders from Baghdad travelling towards Chittagong.

Preachers such as Sultan Balkhi, Shah Ali Baghdadi and Bayazid Bastami were also rumoured to have visited the island.

The eighteenth century marked the time in which Hatiya Island was under the hegemony of Chowdhury Abu Torab Khan, a powerful zamindar who led the first rebellion against the British East India Company in Bengal.
