The Sundarbans was not a centre of national politics, and pretending otherwise would misdescribe it. Through the whole colonial period it was frontier land being cleared, held by lot-holders and worked by recent settlers, and what organised resistance there was took the shape of tenant and sharecropper movements over rent, crop share and the terms of clearance. The one nationally known revolutionary episode connected to the region happened in Calcutta, not in the delta. The largest political event the Sundarbans produced on its own ground is the Tebhaga movement of 1946–47, and its storm centres — Kakdwip and Namkhana — are islands, not towns.
Titumir's movement and the Barasat rising1827–1831
Syed Mir Nisar Ali, called Titumir, organised cultivators in the Narkelberia country at the delta's northern landward edge against cesses levied by local zamindars and against the demands of indigo planters. His followers built a bamboo stockade at Narkelberia and for a short period collected their own dues in the surrounding villages.
परिणाम: A Company force with artillery stormed the stockade on 19 November 1831. Titumir was killed in the action and his principal associates were tried; the movement did not survive him.
The Indigo revolt1859–1860
Cultivators across Nadia, Jessore and the 24 Parganas — the districts the Sundarbans settlers were drawn from — refused to sow indigo under the advances system, withheld their fields and took planters to court.
परिणाम: The Indigo Commission reported in 1860 and cultivation contracted sharply in Lower Bengal. The refusal was largely successful, which is unusual for a nineteenth-century agrarian movement.
The Tebhaga movement1946–1947
Sharecroppers demanded that the landholder's share fall from one half to one third of the crop, and that the harvest be stored on the sharecropper's own threshing floor until it was divided. Kakdwip and Namkhana were the principal centres in the delta, with action also at Canning, Bhangar and Sonarpur; participation by women was a marked feature.
परिणाम: The movement was met with arrests and police action through 1947. The one-third share it demanded was later written into tenancy law.
