Question

why did the british bengal division

Answer 1

It needs a fragmentation or division of British-India in its territorial boundary. Muslims were in favour of this partition relieving them from lower condition under the Hindu hegemony. So, partition of Bengal was held under the auspicious of Lord Curzon, British viceroy of India in 1905.

Answer 2

According to the British government Bengal was too big to be efficiently administered by a single provincial government.

Real reason

1. Bengal was the nerve center of Indian nationalism at that time. So the British wanted to stop the rising tide of nationalism.

2. To reduce Bengalis to a minority in Bengal itself

3. To divide Hindus and Muslims

Did all this on my own

Hope it helped :)
