Political map of South & Southwest Asia 16 October 1905 (Partition of Bengal): British India was dominated by Bengal (Bengal Presidency), whose 80 million people made up over a quarter of the population of the subcontinent. In a bid to make governing Bengal easier, it was split into two provinces in 1905 (Partition of Bengal (1905)) - a largely Muslim east and a largely Hindu west. This act was strongly opposed by Indian nationalists (Indian National Congress), who saw it as an attempt to undermine the Congress party and stir up religious tensions. Eventually the British gave way, reuniting Bengal in 1912, but by this time Muslim separatism was emerging as a political force (All-India Muslim League) as the nationalists had feared.
