The 19lh Century Faraizi Movement in eastern Bengal developed under the leadership of:

The Faraizi Movement was a significant 19th-century Islamic religious reform movement in Eastern Bengal, founded by Haji Shariatullah in 1818 [3]. The term 'Faraizi' is derived from 'Fard', referring to the mandatory religious duties ordained by Allah, which the movement sought to enforce among Bengali Muslims. Haji Shariatullah aimed to purify Islam by eradicating un-Islamic social innovations and local customs that had permeated the community [3]. After his death in 1840, the leadership passed to his son, Muhsinuddin Ahmad, popularly known as Dudu Miyan, who transformed the movement into a more revolutionary and agrarian struggle against oppressive zamindars and British indigo planters [2]. While Dudu Miyan played a crucial role in its later organizational and political phase, the movement's development and foundation in the 19th century are primarily attributed to Haji Shariatullah.
