A feature article by Dr. Tawhidul Islam, published on February 26, 2026, explores how Islam entered and expanded in Bengal through economic and trade connections rather than solely through conquest. The piece traces the process from Muhammad bin Qasim’s Sindh campaign in 712 CE to Bakhtiyar Khalji’s conquest of Bengal in 1204 CE, emphasizing that commercial motives and political ambitions often underpinned these military movements.

The article highlights that Arab merchants had established strong trade ties with the Bengal region long before Islam’s arrival, facilitating cultural and social exchanges. These interactions, combined with the later arrival of Sufi preachers, helped spread Islamic ideals among local populations. The author argues that economic interests, maritime trade, and social contact were the main driving forces behind the religious and political establishment of Islam in Bengal.

The analysis concludes that Islam’s foundation in Bengal was primarily shaped by economic motivations and sustained trade relations, which fostered both cultural integration and religious transformation across the subcontinent.
