The Jute Myth: Hemp, Rice Sacks, and Colonial Burma's Export Boom

By the early twentieth century, a sack of rice leaving the Rangoon docks was as much a symbol of colonial Burma as the pagodas along the Irrawaddy. Burma had become the largest rice exporter on earth, feeding markets from Calcutta to Hamburg, and every one of those millions of tons moved in a coarse woven bag that period writers almost always called, loosely, gunny, or sometimes just hemp sacking. The casualness of that language has caused a century of confusion. Gunny, in the English of colonial clerks, traders, and even encyclopedia editors, was a catch-all word that could mean jute cloth or hemp cloth interchangeably, and nobody at the time felt much urgency to specify which.
That sloppiness matters now because it has led modern readers, and more than a few historians, to assume Burma's rice boom ran on homegrown hemp fiber. It didn't. The sacking that carried Burmese rice around the world was almost entirely jute, grown and woven in Bengal and shipped in by the boatload from Calcutta's mills. Hemp did exist in colonial Burma, but as a minor domestic crop grown in small plots alongside indigo and vegetables, and, under a completely separate set of laws, as a regulated narcotic that British administrators were actively trying to suppress. Sorting out which plant did which job is the real story behind the sacks stacked on Rangoon's wharves.
Gunny, Jute, Hemp: Sorting Out a Colonial-Era Word Mess

The word gunny gets thrown around in nineteenth-century sources the way we might use the word plastic today: a material category, not a precise botanical identifier. Officials writing shipping manifests, merchants drafting invoices, and reference works alike used it to mean any coarse, heavy, loosely woven fabric suitable for bagging bulk goods, whether that fabric happened to be woven from jute fiber or hemp fiber. An 1870s edition of the Encyclopaedia Britannica, in its entry on British Burmah, lists gunny bags plainly among the province's articles of import. The same entry, in a separate passage, notes that hemp was grown locally in Burma, mentioned in the same breath as indigo and vegetable crops grown for local consumption.
That juxtaposition is easy to misread if you skim it, and it's precisely the kind of passage that has sent later researchers hunting for a domestic Burmese hemp-sacking industry that never existed at any meaningful scale. The two facts sitting side by side in the same reference work were describing entirely different things: an imported manufactured good on one hand, a small-acreage local crop on the other. Nothing in the record suggests the two were connected.
This wasn't a new linguistic habit invented for Burma's rice boom. The British East India Company had been shipping gunny sacks into Southeast Asian ports since the seventeenth and eighteenth centuries, long before Burma's deltas were cleared for large-scale paddy cultivation. Jute sacking was already the standard packaging material for bulk agricultural exports across British Asia well before Burma became a major rice producer, which means the vocabulary problem was baked in from the start. Anyone today scanning old customs ledgers, shipping records, or merchant correspondence for evidence of hemp bags is, in the overwhelming majority of cases, reading period shorthand for jute.
Bengal's Mills Supplied the Bags That Moved Burma's Rice

Strip away the loose terminology and the material reality is straightforward: the sacking that bagged Burma's rice was woven jute, and virtually none of it was grown or processed inside Burma. It arrived by ship from Calcutta and the other mill towns strung along the rivers of Bengal, where jute cultivation and manufacturing had concentrated into a genuine industrial cluster. Burma grew the rice; Bengal supplied the bags that carried it to the rest of the world. That dependency is one of the quieter facts of the colonial rice trade, and it rarely gets a mention in histories that focus on paddy acreage, mill output, and export tonnage.
The concentration of jute production in Bengal wasn't accidental. The delta region had the specific combination of conditions the crop and its processing required: abundant fresh water for retting the fiber, a dense agricultural labor force, river transport networks for moving raw jute to mills, and, by the mid-nineteenth century, an established milling infrastructure built around steam-powered looms in and around Calcutta. Burma had none of this at comparable scale. Its colonial economy was organized almost entirely around clearing delta land for paddy, not around fiber cultivation or textile manufacturing.
The practical consequence is that nearly every bag of rice that left Rangoon bound for Europe, India, or Ceylon had begun its life as raw jute fiber grown hundreds of miles away, on the other side of the Bay of Bengal. This arrangement is a tidy illustration of how British India's provinces functioned less like a collection of self-sufficient territories and more like specialized components of a single integrated economic system. Bengal supplied fiber and manufactured sacking; Burma supplied grain; shipping lines and trading houses stitched the two together. Neither half of that chain could have operated at the scale it reached without the other.
How Burma Became the World's Rice Granary
Burma's rice exports surged nearly fivefold from about 732,000 tons in the early 1870s to 3.6 million tons by 1920, reflecting the colony's rise as a dominant global rice exporter.
The numbers behind Burma's rise as a rice exporter are worth laying out plainly, because they show just how fast the demand for imported sacking had to scale to keep pace. Annual average rice exports climbed from roughly 732,000 tons in the early 1870s to about 2.5 million tons by 1900, and then to 3.6 million tons by 1920. The land under rice cultivation expanded just as dramatically, growing from around 1.5 million hectares in 1885 to 4 million hectares by 1910, with total production rising from roughly 2 million to 6 million tons over that same stretch. This was one of the fastest agricultural export expansions anywhere in the colonial world.
Behind those figures stood a handful of British trading houses that controlled the milling, shipping, and export side of the business almost end to end: Bulloch Bros., Steel Bros., Mohr Bros., and the Liverpool-based Joseph Heap and Co. among them. These firms built and ran the rice mills clustered around Rangoon, chartered the ships that carried the grain abroad, and brokered the sales in markets overseas. Their physical footprint is still visible today: Rangoon's General Post Office building, a colonial-era landmark that still stands in downtown Yangon, started out as the headquarters of Bulloch Brothers & Company, a Scottish rice-trading firm that was among the most prominent players in the industry.
Every stage of this expansion carried a direct implication for the jute trade on the other side of the Bay of Bengal. More delta land cleared for paddy meant more rice to move. More rice to move meant more mills, more godowns, more ships calling at Rangoon. And every one of those tons needed a sack. The scale-up of Burma's rice economy and the scale-up of Bengal's jute shipments to Rangoon moved in lockstep, two halves of a single supply chain that colonial-era writers rarely described as such, even though the dependency was total.
When Hemp Meant a Drug, Not a Fiber
While jute sacking was handling the practical business of moving rice, actual cannabis in colonial Burma occupied a completely different, and far more adversarial, place in the administrative record. Where hemp fiber barely registered as an agricultural commodity, hemp-as-drug drew sustained attention from British administrators intent on controlling it. The import of hemp drugs into Burma by sea was prohibited in 1874, and cultivation and possession of cannabis were banned outright in the province in 1891, decades before similar restrictions tightened elsewhere in British India.
The scale of the problem, from the administration's perspective, was documented in the Indian Hemp Drugs Commission's report of 1893-94, a sweeping colonial inquiry into cannabis use across British India and Burma. The commission's investigators in Burma found that ganja was being smuggled into the province from outside, while actual cultivation within Burma's borders was small and largely clandestine, reported in scattered pockets such as the districts of Upper Chindwin. There was no significant above-board cannabis agriculture to speak of; what existed operated outside the law almost by definition, given the 1891 ban.
Lay these two threads side by side and the contrast is stark. One strand of the colonial record treats hemp as an agricultural afterthought, a crop worth a passing mention next to indigo and garden vegetables, present but economically negligible. The other strand treats hemp as a narcotics problem serious enough to warrant import bans, cultivation prohibitions, and a formal multi-year government commission. Neither thread has anything to do with the sacks of rice moving through Rangoon's harbor, which is exactly the point: the same English word, hemp, was doing two entirely unrelated jobs in the colonial paperwork, and conflating them produces a badly distorted picture of what the plant actually meant to colonial Burma.
The Conflation Didn't Stay in the Past
The terminology confusion that muddled nineteenth-century trade records never really got resolved, and it is still shaping outcomes in Myanmar today. Native cannabis and hemp species continue to grow wild in parts of Kachin, Shan, and Chin states, a reminder that the plant has a long, mostly undocumented presence in the country's upland regions outside the colonial record's narrow focus on narcotics enforcement and port trade. In recent years that wild presence has collided with renewed interest in industrial hemp as a legitimate cash crop.
A 2019 push to establish licensed industrial hemp cultivation in Myanmar, backed by foreign investment, ran directly into the old conflation between fiber and drug. A licensed U.S.-Myanmar hemp farming venture in Ngazun Township was raided by authorities despite its licensed status. The farm's owner, John Todoroki, was arrested and later released on bail, prosecuted under a 1993 narcotics law that makes no legal distinction between industrial hemp, which contains negligible levels of THC, and marijuana grown for psychoactive use.
That legal gap is not a technicality; it's the same fundamental problem that shows up in the 1870s Britannica entry lumping gunny bags and local hemp together, just relocated to a modern courtroom. A country's laws, like its trade records, depend on precise categories to function, and Myanmar's current narcotics framework simply doesn't have one for industrial hemp as a distinct agricultural product. The throughline connecting a nineteenth-century encyclopedia's loose use of the word gunny to a 2019 raid on a licensed hemp farm is a single, continuous story: imprecise language about a plant's identity keeps producing real consequences, whether that's a historian misreading a shipping manifest or a farmer facing prosecution under a law never built to tell the two plants apart.
Strip away a century of loose terminology and the picture that emerges is clear enough: the sacks that carried Burma to the top of the global rice trade were jute, grown and woven in Bengal, not hemp cultivated on Burmese soil. That's a correction worth making plainly, because the two fibers keep getting blurred in both the old colonial record and in present-day writing that assumes gunny meant hemp simply because the words got used interchangeably a century and a half ago.
Myanmar's actual relationship with hemp runs on an entirely separate track from the rice trade, and it always has. In the colonial period it was a minor crop worth a passing mention next to indigo and garden vegetables, and, under a different legal framework entirely, a narcotic banned outright by 1891 and actively policed thereafter. Today it's a modern agricultural ambition still tangled in a 1993 law that can't distinguish a fiber crop from a controlled drug, a gap that has already cost one licensed farmer his liberty, at least temporarily, over a plant with no meaningful intoxicating potential.
Untangling gunny from hemp isn't an exercise in pedantry for its own sake. It's a demonstration of how imprecise language in a colonial trade ledger or an old encyclopedia entry can outlive the empire that produced it, quietly shaping how a country's agricultural history, and its present-day legal obstacles, get understood or misunderstood generations later. Burma's rice reached the world on Bengal's jute. Myanmar's hemp industry, if it ever gets built, will have to do its own work of separating the crop from the century of confusion still attached to its name.
