This academic research is primarily concerned with two fundamental issues. The first objective is to depict Buddhist impacts on Turkic religious thoughts during Islamisation. The second issue is how this syncretic process aided Turks in capturing the Bengal region with the assistance of local Buddhists. The historical tie between Bengal and Central Asia dates to the first century BCE. In it, the northern Indian Maurya empire and the Turkish Huns played an important role. Through their efforts, Buddhism spread throughout Central Asia. Besides, Islam encountered significant opposition from Buddhism in Bengal and Central Asia. Over time, the Turks erected a Sultanate in Delhi and then hailed Bengal for the same purpose. As a result of an exhaustive search of the academic research on the database, applicable works have yet to be found related to running scholarly works. This study will employ a qualitative approach with a thematic focus. In addition, secondary categorical data from Turkish, English, and Bengali literature will be utilized in the current scholarly study.
