What integra wrote about the division of the then Bengal Province in 1905 and the subsequent formation of East Bengal-Assam Province is based on history, and not on fiction.
The old Bengal Province was reinstated probably in 1910 when the Bangali intellectual Hindus of Calcutta started a movement against the changes that benefitted Bangali Muslims. Henceafter, the All-India Muslim League was formed in Dhaka that led the Pakistan Movement.
Exactly! The second part was never mentioned in the link. Bengal was reunited again! Half-truth is no better than lie.
About the bold part. Although The movement was predominantly led by people who were born Hindus, it was never based on any Hindu ideology. Please don't degrade their contribution by calling them Hindu intellectuals.
Remember your National Anthem was composed to induce encouragement to anti-partition movement in Bengal. It was more secular and equally impacting(though in a regional level) and same in nature to Satyagraha movement by Gandhiji in a decade after.
Regarding the benefits of Bengali Muslims - Both Hindu and Muslim educated people supported the movement, the only objection came from groups led by Nabab of Dhaka and other Urdu-speaking people who were looking for only his benefits,
now we all know how they were loyal to British during sepoy mutiny thus awarded the Nabwab title. Accepting that major Bengali muslims were peasant class in East-Bengal and some Jamindars were tyrant(although both hindu and muslims were victims of their tyranny), do you really think, Nawbab cared for poor deprived people in general. They saw their influence is fading, so they opposed, simple as that.
Though, I think, the partition should have been happened at that time, we would have avoided the unnecessary blood-spill at 40s and the present distance between Bengalis of both side. But you people yourselves proved untrue the whole reason you parted for, by your independence struggle.
