A 2,300-Mile Hedge Across India, Grown to Guard a Tax on Salt

In 1869 there was a hedge running across India. Not a garden hedge. This one stood ten to fourteen feet high and twelve feet thick, grown from thorn trees packed so tightly the men who planted it called it impassable to man or beast.

Where the ground would not hold plants, they filled the gaps with stone walls and ditches. The barrier ran from the Indus to the Mahanadi near the east coast: 2,300 miles, patrolled night and day by nearly 12,000 men from 1,727 guard posts.

Its job was to stop people carrying salt.

We know this because the man who ran India’s finances wrote it down. Sir John Strachey published the figures in 1882 and called the arrangement “a monstrous system to which it would be almost impossible to find a parallel in any tolerably civilised country.” He was describing his own government.

A tax on what the body burns off daily

Salt is not a seasoning you can skip. Sodium keeps your blood volume up and your nerves firing, and you lose it every time you sweat. A 2008 study of outdoor workers found that ten hours of labour in moderate heat costs a person 12 to 15 grams of salt. The World Health Organization tells a desk worker to stay under 5 grams.

So salt in India was never a luxury. It was a bill the body sends every morning, bigger for the man with the hoe than for the man watching him.

The East India Company began squeezing the Bengal salt trade in the eighteenth century, and under the Crown it hardened into a monopoly, meaning one seller and no other, by law. The Indian Salt Act of 1882 let the government license who could make salt and set its duty and minimum price. Making salt from the sea without a licence was a crime, punishable by 500 rupees or six months of hard labour.

Enforcement was not symbolic. Magistrates recorded 7,653 convictions for illegal salt manufacture in 1875 to 1876. A Bombay court had ruled that “manufacture” covered having naturally formed salt on your person, and coastal villagers were still prosecuted in the 1920s when floods left salt on their doorsteps.

It paid, too. Salt was an excise, a tax on a good where it is made or sold inside the country, and in 1879 to 1880 it raised £7.27 million, more than a third of everything Strachey counted as taxation. The Duke of Argyll had named its appeal in 1869: an indirect tax is “paid without observation by the consumers.”

A tax nobody notices. That was the design brief, and the hedge was the fence around it.

The hedge, minus the legend

The line existed because provinces charged different rates: salt was cheap in Rajputana, dear in Bengal, worth smuggling.

One of the men who ran a stretch of it was A. O. Hume, commissioner of inland customs and later a founder of the Indian National Congress. He wrote that the hedge was to the customs line what the Great Wall once was to China.

Then it went. On 1 April 1879 the whole line was abolished: Lord Lytton had equalised the salt duty in 1878 and leased the Rajputana salt lakes, so the barrier had no job left. The thorn was cleared for roads and fields, and within a lifetime nobody remembered it.

Be careful with what you read about it now. Nearly everything in circulation about the “Great Hedge of India” goes back to Roy Moxham’s 2001 book, still the only book-length study. In 1997 he found an 1879 map at the Royal Geographical Society that fixed the route, and later walked a surviving stretch near Etawah.

But the line was never a lost secret. It sits in the empire’s own published accounts, payroll included. And the popular picture of one unbroken wall of living thorn is neater than the record. Strachey called the barrier “principally” hedge, “supplemented by stone walls and ditches,” and Moxham’s own 1878 figures give about 411 miles of good live hedge against some 1,110 miles of inferior hedge, dry thorn or stone wall.

Did it make people ill?

Here the honest answer costs you a better line.

Strachey, defending the duty, gave away more than he meant to. He called it an exaggeration to say the tax bore harshly on the poor, then conceded that “it was not open to question that very large numbers of our subjects failed to obtain a full supply of salt.” In Madras and Bombay, where the duty was lowest, people ate twice as much salt per head as in northern India, where it was dear.

That undoes the official case. Administrators insisted demand for salt was fixed, so taxing it hurt nobody. Their own figures said otherwise, as Gopal Krishna Gokhale told a royal commission in 1897.

Whether the shortfall made people ill is disputed. Moxham argued in the Economic and Political Weekly in 2001 that heavy salt taxation in Bengal caused real salt starvation. Miles Taylor, writing in 2023, disagrees: the official minimum of 12 grams a day is close to what people eat now, and the monopoly never produced anything like the famines caused by grain shortages. Neither side has a death toll.

The figure you often see, that salt cost a labourer around a sixth of his income, is Moxham’s reading of testimony to a parliamentary committee in 1836. Treat it as an estimate for early nineteenth century Bengal; by 1930 the duty was much smaller.

Why Gandhi picked salt, when his own side did not want him to

By 1930 Congress had committed to full independence and needed somewhere to start. Gandhi chose salt, and plenty of his colleagues thought he had it wrong.

Motilal Nehru and Indulal Yajnik expected a stunt. Jawaharlal Nehru wanted a rival government. Vallabhbhai Patel wanted a march on Delhi. Newspapers on both sides made jokes. Unlike opium or liquor, salt had never had a mass movement behind it.

His answer is in his letter to Viceroy Lord Irwin of 2 March 1930. “I regard this tax to be the most iniquitous of all from the poor man’s standpoint,” he wrote, because “salt is the one thing he must eat more than the rich man.” Irwin brushed him off.

A commercial current ran the same way, and it usually gets left out. Indian salt makers had lobbied for years against a system built around imported “Liverpool salt,” and weeks before the march their trade federation called for the duty to go. Gandhi had read the report.

240 miles, 24 days, one lump of mud

Civil disobedience means breaking a law on purpose, in the open, and taking the punishment. Gandhi announced his plan in advance.

He left Sabarmati Ashram outside Ahmedabad on 12 March 1930 with 78 followers and covered about 240 miles in 24 days, stopping for prayers and speeches in the villages on the route.

On 6 April, at Dandi on the Gujarat coast, after prayers and a sea bath, the 60-year-old bent down and picked a lump of natural salt off the shore. He said he was shaking the foundations of the British Empire.

Then the country copied him, boiling seawater on beaches, scraping salt off flats, raiding depots. Britannica puts about 60,000 people in jail by the end of 1930, and other estimates run higher. Police took Gandhi at Karadi on the night of 4 to 5 May.

On 21 May, Sarojini Naidu led about 2,500 volunteers to the Dharasana salt works. Police with steel-tipped clubs beat down the front rank, and the next rank walked forward, and the next. The American reporter Webb Miller counted 320 injured, reported deaths, and cabled it worldwide.

What it won, and what it did not

On 5 March 1931 Gandhi and Irwin signed a pact. Prisoners went free, fines were dropped, picketing was allowed, Congress agreed to attend the second Round Table Conference, and coastal villagers won the right to make salt for their own use and sell it locally.

The monopoly survived. So did the duty. Surveillance of the salt villages ended, licensing moved to the post office, but by the mid 1930s salt was back to 13 percent of all the tax the Raj collected. The one clean law it produced protected Indian salt makers from foreign competition.

Nehru described feeling “a great emptiness as of something precious gone.” Two later analysts of nonviolent campaigns, Peter Ackerman and Christopher Kruegler, judged it a failure and a British victory.

The tax outlived the march by sixteen years, ending on 1 April 1947, four and a half months before independence, abolished by the interim government. As Miles Taylor points out, it was the only tax the British ever removed in India: one of the last acts of the Raj, not the first act of a free country. In 1953 Nehru’s government brought in a salt levy of its own.

The argument he actually won

For eighty years the official line had been that the salt tax was invisible, that Indians paid it without complaint, that it reached everybody and troubled nobody. The design depended on nobody looking at it.

A man walking to the sea for twenty-four days and stooping to pick up mud made that impossible. The picture explained itself on any front page: a government that had made it a crime to pick salt off a beach.

That was never a fight about the price of salt. It was a fight over who got to describe what the empire was, and after Dandi the empire lost it.
