Why was reunification of Bengal done in 1911?

The reunification of Bengal in 1911 was primarily driven by political considerations by the British colonial government. The original partition of Bengal in 1905 aimed to weaken nationalist movements by dividing the largely Hindu west from the predominantly Muslim east. However, widespread protests and backlash from Indian nationalists led to its reversal. By reuniting Bengal, the British hoped to quell unrest and manage the growing nationalist sentiments more effectively.
