Bangladesh

Historical overview

The territory that constitutes present-day Bangladesh has a long history shaped by ancient Bengal, regional kingdoms, trade, cultural exchange, religious traditions, colonial administration, linguistic identity, and political movements.

The region formed part of several historical political formations, including the Maurya and Gupta empires, the Pala dynasty, the Sena dynasty, the Bengal Sultanate, and the Mughal Empire. Bengal subsequently came under British East India Company control following the Battle of Plassey in 1757 and the acquisition of the Diwani in 1765.

The nineteenth and twentieth centuries witnessed major social, educational, cultural, and political developments. The Bengal Renaissance, anti-colonial movements, debates over representation, and the growth of Bengali linguistic and cultural identity helped shape modern political consciousness.
