In the Anti-Partition Movement, the entire national leadership of Bengal was involved.
Initially, the prominent leaders were the moderate leaders like Surendranath Banerjea and Krishna Kumar Mitra were involved but later militant and revolutionary nationalists took over in the later stages.
The Anti-Partition Movement was initiated on 7- August 1905.
On that day a massive demonstration against the partition was organised in the Town Hall in Calcutta.
From this meeting delegates dispersed to spread the movement to the rest of the province.
