Reconstruction
In 1882, the colonial Government of India consolidated important salt-revenue restrictions under the Indian Salt Act while reducing duties toward a broadly uniform rate of two rupees per maund, a unit of roughly 37 kilograms. Uniformity did not mean freedom. The state retained extensive authority over manufacture, collection, transport, storage, and sale, enabling officials to license production, levy duty, seize illicit salt, and punish unlicensed activity. The measure belonged to a much older system: the East India Company had controlled salt revenue in Bengal since the eighteenth century, long before the 1882 legislation.
Salt was an unusually powerful taxable food because virtually everyone needed it. It supplied physiologically necessary sodium and chloride, seasoned everyday meals, and helped preserve fish, meat, vegetables, and pickles where refrigeration was unavailable. A fixed charge on this universal commodity consumed a larger share of a poor household’s resources than of a wealthy household’s. Contemporary critics therefore described the duty as especially burdensome to poorer consumers, although the exact effect varied with regional prices, wages, diets, and access to untaxed salt.
Production was geographically diverse. In parts of Bengal, workers known as malangis concentrated brine or saline earth and boiled it in earthen vessels over grass, straw, or wood fires. Along the Madras and Bombay coasts, seawater was commonly evaporated in solar salt pans. Inland sources included the brines of Rajputana, while imported Cheshire salt reached eastern India through Calcutta. Colonial policy did not create these technologies, but it determined who could use them legally and how salt moved through depots, customs points, auctions, and licensed markets. Scholarship indicates that these policies suppressed or displaced indigenous production in several regions while protecting revenue and, at times, imported British salt.
By 1930, salt had become more than a revenue commodity. Mohandas Gandhi selected it as the focus of civil disobedience because the law reached across class, region, and religious community. On March 12, he left Sabarmati Ashram with 78 initial marchers and travelled roughly 385 kilometres to Dandi. On April 6, he publicly broke the salt law. The gesture encouraged people elsewhere to collect, manufacture, possess, and sell prohibited salt, transforming an ordinary seasoning into tangible evidence that colonial sovereignty extended into kitchens and coastal landscapes.
The campaign did not immediately abolish the tax. The 1931 Gandhi–Irwin settlement permitted limited local salt making near some coastal areas, while the wider revenue structure survived. Salt duty was ultimately abolished from April 1, 1947. Modern India still regulates salt as an essential commodity and uses it as a vehicle for iodine and sometimes iron fortification. That public-health role is not a direct continuation of colonial taxation, but it demonstrates why control over a universally consumed food remains politically consequential.
Historical context
The first synchronous all-India census of 1881 enumerated approximately 254 million people across British-administered territories and princely states; by the 1931 census, the total approached 353 million. Most people remained rural, but railways, steamships, ports, and large commercial cities were integrating regional food markets. Calcutta was British India’s capital until 1911 and remained a major port and administrative-commercial centre afterward. Across the same period, mass nationalist politics expanded, culminating in the Indian National Congress declaration of complete independence in January 1930 and the Civil Disobedience Movement that followed.
Evidence
Written sources
StrongLegislation, colonial financial statements, parliamentary debates, administrative reports, newspapers, and Gandhi’s writings directly document the salt laws, duties, official justifications, criticism, and the 1930 campaign.
Food identification
StrongThe taxed commodity is securely identified as culinary and preservative salt, principally sodium chloride, although historical salt varied in purity, grain, source, and minor mineral content.
Dating
StrongThe Indian Salt Act and duty changes are documented in 1882, while Gandhi’s march began on March 12, 1930, and the salt law was broken at Dandi on April 6, 1930. These dates frame the card but not the entire history of colonial salt extraction.
Preparation method
ModerateRegional records document solar evaporation, brine concentration, and boiling saline material with biomass fuel. No single production method represents all salt consumed in British India.
Geographic attribution
ModerateCalcutta was central to Bengal’s salt administration, auctions, imports, and trade, but the 1882 regime was broader than Calcutta and the defining 1930 protest occurred between Sabarmati and Dandi in western India.
Historical interpretation
StrongThe interpretation of salt control as a revenue mechanism and political instrument is supported by archival scholarship. The precise household burden and relative importance of revenue, import policy, and producer interests varied over time and remain subjects of scholarly analysis.
Archaeological
LimitedArchaeology is not the principal evidentiary basis for this modern fiscal and political event. Production landscapes or equipment may have material remains, but the central claims are established through written and photographic records.

Limitations
- moderatetitle
The wording may imply that salt first became a tool of colonial extraction in 1882. East India Company control of salt revenue in Bengal began in the eighteenth century; 1882 is better understood as a year of legislative consolidation and duty reform.
- moderatecoordinates
Calcutta is defensible as a centre of Bengal salt administration and trade, but it is not a sufficient location for the entire event. The 1882 regime was pan-regional, and the climactic 1930 Salt March occurred from Sabarmati to Dandi in Gujarat.
- moderatedescription
The description classifies the evidence as historical and archaeological synthesis, but the central claims are supported overwhelmingly by legislation, administrative archives, parliamentary debates, journalism, photographs, and political writings rather than archaeology.
- minoris technology
The card principally concerns taxation, monopoly, trade, and political resistance. Salt-making technologies are relevant context, but the Salt Act and tax were policies rather than technologies.
