The cause of the Partition of Bengal in 1905 was primarily administrative and aimed at improving governance but was heavily influenced by political motives. The British colonial government aimed to divide the province of Bengal for easier management, citing issues related to communication and administration due to its vast size and population. However, the decision was also perceived as a tactic to weaken nationalist movements by creating religious divisions, as Bengal had a considerable Hindu majority in the West and a Muslim majority in the East. This division sparked widespread protest and unrest, leading to its reversal in 1911, but it intensified communal tensions in the region.
