Partition of Bengal (1905)

Background

Bengal Presidency under British administration stretched from Assam to Odisha and held a population exceeding 78 million, larger than any other province in India. Curzon's government presented the partition as an administrative measure to ease the burden on a single provincial government and to improve development in the underserved eastern districts. Critics at the time and since have argued that the division, which placed a Muslim majority in the new eastern province and left a Hindu majority in the western one, was designed at least in part to weaken Bengali political unity and the influence of the Calcutta-based Hindu professional and landholding classes who dominated Congress politics in the province.

Reaction and the Swadeshi movement

The partition triggered the largest mass agitation India had seen to that point. Bengali Hindus in particular viewed it as a deliberate attempt to divide their linguistic and cultural community. The response took the form of the Swadeshi movement, which promoted boycott of British goods, particularly Manchester cloth, and encouraged the purchase of Indian-made products instead. Public meetings, the singing of Bande Mataram, and the tying of rakhi bands between Hindus and Muslims as a symbol of unity became common forms of protest, associated especially with Rabindranath Tagore. Leaders identified with the more assertive wing of Congress politics, including Bipin Chandra Pal, Bal Gangadhar Tilak and Lala Lajpat Rai, used the agitation to argue for methods beyond petition and prayer, contributing to the split between the "Moderate" and "Extremist" factions of Congress at its 1907 Surat session. The movement also gave early organizational experience to figures who later became prominent in revolutionary and constitutional nationalist politics, and it stimulated the growth of Indian-owned industry and educational institutions, including national schools established outside government control.

Reunification and consequences

Faced with sustained unrest, the government reversed the partition in 1911. King George V announced the reunification of Bengal at the Delhi Durbar, alongside the decision to move the capital of British India from Calcutta to Delhi, a step widely read as an attempt to reduce Calcutta's standing as a centre of nationalist agitation. Assam was separated out as its own province, and new boundaries were drawn that did not restore the exact pre-1905 arrangement. The episode is generally treated by historians as a turning point: it demonstrated the capacity of organized, extra-constitutional protest to force the colonial government to reverse a major policy decision, and it left a lasting association between provincial partition and communal politics that resurfaced in later debates over Bengal and Punjab in the 1940s.
