What is the Partition of Bengal?

The Partition of Bengal was a territorial reorganisation of the Bengal Presidency announced on 16 October 1905 by Viceroy Lord Curzon. Bengal, with a population of 78.5 million, was British India's largest province. Curzon divided it into two parts: the western half (largely Hindu-majority, including Bihar and Odisha) and the eastern half (largely Muslim-majority, with its capital at Dhaka), which was merged with Assam.

While the British justified the partition on administrative grounds (the province was too large to govern effectively), the real motive was political — to weaken the growing Bengali nationalist movement by dividing Hindus and Muslims. The partition triggered massive protests, gave birth to the Swadeshi Movement and the boycott of British goods, and radicalised Indian nationalism. Revolutionary organisations like Anushilan Samiti and Jugantar emerged during this period. The partition was annulled in 1911 by Lord Hardinge, but its communal legacy endured — the All-India Muslim League was founded in Dhaka in 1906, partly as a consequence.
