The History of Potato: From Andean Hidden Treasure to the World’s Staple Food

In 1771, Antoine-Augustin Parmentier — a Parisian pharmacist and military surgeon — presented a bouquet of potato flowers to Louis XVI and Marie Antoinette.^[1] The king is said to have worn the blossoms as a hat ornament, the queen as a hairpin. That same year, Parmentier laid out a potato field on the outskirts of Paris at Sablons, posted armed guards during the day, and deliberately withdrew them at night. Predictably, village farmers began climbing the fence each night to steal and plant the potatoes. The entire affair was staged.

At the time, certain French provinces had ordinances banning potato cultivation since 1748, driven by unfounded fears that the crop caused leprosy.^[2] Parmentier had first eaten potatoes in a Prussian prisoner-of-war camp. In France the tuber was fit only for pigs, yet it had kept prisoners of war alive. After returning home, he became convinced that potatoes could prevent famine and devoted his life to promoting them. The royal garlands, the forbidden field, the nocturnal thefts — all of it was a marketing campaign.

Looking at why such an elaborate performance was necessary reveals 8,000 years of history that the potato had already traveled.

On the Shores of Lake Titicaca: The Birth of the Potato

The wild ancestors of the potato (Solanum tuberosum) grew in the borderlands of present-day southern Peru and northwestern Bolivia, at Andean altitudes of 3,500 to 4,200 metres above sea level.^[3] The area around Lake Titicaca remains the world’s foremost centre of potato genetic diversity, where Indigenous farmers in Peru and Bolivia continue to cultivate more than 4,000 traditional varieties by traditional methods.^[4]

Genetic studies show that potato domestication began from a single origin roughly 7,000 to 10,000 years ago.^[3] This contrasts with chili peppers — another American crop — which were domesticated independently in multiple regions. A 2016 study published in PNAS identified 50 starch microfossils matching cultivated potatoes on stone tools recovered from the late archaic site of Jiskairumoko in the south-central Peruvian Andes.^[5] This evidence suggests that potatoes were already established as food in the region by around 4,000–3,000 BCE.

It is crucial to note, however, that Andean potato culture never remained at the level of simply “digging and eating.” Long before the Inca Empire expanded, Andean peoples had developed sophisticated techniques for processing and storing potatoes.

Chuño: Humanity’s First Freeze-Dried Food

At 4,000 metres above sea level, nighttime temperatures can drop to minus 20 degrees Celsius. The Aymara and Quechua peoples of the Andes turned this brutal climate to their advantage. By spreading harvested potatoes on the ground to freeze overnight, drying them under the intense daytime sun, and repeatedly trampling them to press out moisture, they produced chuño — a fully dehydrated potato.^[6]

What this process achieves is the principle of freeze-drying, which modern science only “invented” in 1906. Chuño can be stored for more than 20 years; Inca armies carried it as provisions on military campaigns, and it was used through the empire’s warehouse system — the qollqa — as a strategic food reserve against famine.^[6]

This fact carries important implications. There is a tendency to describe potatoes as “a plant that Europe discovered and spread to the world,” yet Andean civilization had already possessed a complete agricultural system for cultivating, processing, and storing potatoes for thousands of years. What the Spanish conquistadors encountered in the sixteenth century was not a primitive plant but the core food resource of a highly sophisticated civilization.

The Spanish Conquistadors’ “Discovery”: Misunderstanding and Neglect

When Francisco Pizarro began conquering the Inca Empire in 1532, the Spanish showed little interest in this subterranean tuber that formed the staple of the Andean diet. The first European to record potatoes in writing was the Spanish missionary Pedro Cieza de León, who mentioned a plant called “papa” eaten by the Inca in his 1553 work Crónica del Perú.^[7]

Potatoes are thought to have first arrived in Spain sometime around the 1570s, though the precise route and date remain unclear.^[7] What is certain is that the initial European response was cool or suspicious. The potato belongs to the nightshade family (Solanaceae), which includes highly toxic plants such as belladonna and mandrake. European concern about the potato’s toxicity was not entirely without foundation — potato leaves and green potatoes do contain the toxic compound solanine.^[8]

The fact that potatoes appear nowhere in the Bible deepened suspicion. Some Europeans of the time held the belief that one should not eat plants not mentioned in Scripture, and potatoes were sometimes called “the devil’s plant.”^[2] The most practical resistance, however, arose from class prejudice. Potatoes grew underground and served as animal feed. The conceptual barrier — that humans should not eat what was fit only for beasts — kept potatoes off European tables for decades across the continent.^[2]

Famine Breaks Down Prejudice

Paradoxically, it was not abundance but famine that spread potatoes across Europe. Ireland is the defining example.

For the smallholders of seventeenth-century Ireland, potatoes were an ideal crop. They produced large quantities of calories from a small plot, grew on poor soil, and stored relatively easily. By the eighteenth century, the diet of Ireland’s poorest farmers had become virtually a single-crop dependency on potatoes.^[9] The increased calorie supply that potatoes provided caused the Irish population to grow rapidly. Meanwhile, in Germany and Prussia, Frederick the Great (Friedrich der Große) pursued a state-level policy to promote potatoes. In 1756 he issued an edict mandating their cultivation,^[10] and in a manner similar to Parmentier’s, he created a royal potato field and deliberately relaxed the guards to encourage farmers to “steal” the crop. His aims were to stabilize grain prices and secure food supplies for his army.

By the late eighteenth century, potatoes had already achieved a substantial position in Europe. In Ireland, Belgium, the Netherlands, Prussia, and Poland, between 10 and 30 percent of the total population depended on potatoes as a staple; in Ireland the figure reached 40 percent.^[9] Economic historians have found that a considerable share of Europe’s eighteenth-century population growth can be attributed to the introduction of potatoes and other New World crops.^[11] Viewed in this light, the potato was the hidden engine of European modernization.

The Irish Famine: The Catastrophe of Monoculture

The very same qualities that allowed the potato to serve as a lifesaver were what made it capable of becoming a catastrophe — its high caloric density and ease of cultivation bred excessive dependence.

In the autumn of 1845, a strange change appeared in the potato fields of Ireland. Leaves turned black and rotted; harvested tubers turned soft and putrid within days. The cause was late blight, caused by the oomycete Phytophthora infestans.^[9] This pathogen is believed to have been introduced from the Americas to Europe, and between 1845 and 1849 it devastated Ireland’s potato harvest for four consecutive years.

The result was catastrophic. Ireland’s population, approximately 8.4 million in 1844, fell to 6.6 million by 1851.^[9] Around one million people died from starvation and disease, and more than a million others emigrated from Ireland. The wave of emigration triggered by this Great Famine continued for decades afterward, becoming the direct origin of an Irish diaspora numbering around 80 million people.^[9]

Historians do not view this event as a simple natural disaster. The British government, which ruled Ireland at the time, has been criticized for permitting the continued export of other foodstuffs from Ireland even during the famine and for delaying relief; the Great Famine is remembered as the event that intensified Irish nationalism and formed the historical backdrop for the subsequent independence movement.^[9]

Yet one structural cause of the disaster is clear. The potato grown in Ireland was almost entirely a single variety called the Irish Lumper, which proved extremely susceptible to blight.^[9] The event demonstrated how catastrophically costly the loss of the varietal diversity developed over thousands of years in the Andes could be when it was stripped away in the process of transplantation to Europe.

Spread Across the World: How Different Civilizations Adopted the Potato

The process by which potatoes spread beyond Europe and around the world unfolded in very different ways depending on each civilization’s existing food culture and social structure.

In Asia, potatoes were often accepted without the stigma of “food for the poor” that was commonly attached to them in Europe. Records suggest that potatoes, which reached China in the late Ming dynasty, were at one point considered a rare and prized ingredient at the imperial court.^[10] In India, potatoes introduced via Portuguese trade in the sixteenth and seventeenth centuries have become one of the core ingredients of Indian cuisine today; India is currently the world’s second-largest potato producer after China.^[12]

In Africa, the adoption process was entangled with a complex history of European colonialism. During the colonial era, potatoes were often a crop that colonial rulers forced upon indigenous workers as food, generating resistance in many regions.^[10] Over the course of the twentieth century, however, potatoes became an important food crop across Africa, and the continent is now among the regions with the fastest-growing production.

In Russia and Eastern Europe, by the eighteenth and nineteenth centuries potatoes had become, alongside rye bread, the foundation of the common table. In Russia, Peter the Great encouraged potato cultivation in the early eighteenth century, though he initially met with resistance from peasants.^[10] By the nineteenth century, however, potatoes had taken deep root in Russian food culture, partly because they also served as the raw material for vodka.

The Paradox of Varietal Diversity: A Legacy That Prevents Catastrophe

One of the most important lessons left by the Irish Famine was the value of genetic diversity. Today, more than 4,000 traditional potato varieties exist in the Andean region, and 151 wild potato species are known worldwide.^[4] This biodiversity is an indispensable genetic resource for developing disease-resistant varieties in modern agriculture.

The International Potato Center (CIP), headquartered in Lima, Peru, conserves samples of more than 4,200 cultivated potato varieties.^[4] This gene bank is a strategic asset in preparation for the threats of climate change and new pathogens, with its core constituted by the biodiversity that Indigenous Andean farmers selected and preserved over thousands of years.

Near Pisac in Peru, there is the “Potato Park,” operated by an Indigenous Quechua community. This conservation farm cultivates more than 900 traditional potato varieties in living form and transmits local agricultural knowledge and rituals alongside them.^[4] The sight of the world’s most advanced seed banks and an Indigenous community’s traditional farming practices working side by side toward the same purpose shows that the birthplace of the potato remains at the centre of its conservation.

The Modern Potato: The World’s Third-Largest Food Crop

Today, the potato is the world’s third-largest food crop by direct human consumption, after rice and wheat.^[12] As of 2023, global potato production stands at approximately 383 million tonnes, and around one billion people include potatoes in their regular diet.^[12]

The leading producers today are China (about 25% of world output) and India (about 16%), marking a shift in the centre of gravity of potato production from Europe to Asia.^[12] The share held by Europe, North America, and the former Soviet Union — which together accounted for most of global potato production through the 1960s — has declined relatively as production in Asia, Africa, and Latin America has grown sharply.

There are biological reasons for the potato’s widespread reach. Its caloric production efficiency per unit of land is higher than wheat or rice; it is rich in protein, vitamin C, potassium, and dietary fibre; and it can be cultivated under a wide range of climates and soil conditions.^[8] The vitamin C content was historically significant: research shows that scurvy — long a problem among European sailors — declined markedly in inland populations as the potato became more widespread.^[8]

What the Potato’s Names Tell Us

How the potato was received by each culture can also be glimpsed in the names given to it.

The Spanish and Portuguese papa is taken directly from the original Andean Quechua name.^[7] The English word potato derives from batata, the Taíno word of the Caribbean for the sweet potato; early Spanish explorers confused the potato and the sweet potato.^[7] The French pomme de terre means “earth apple,” while the German Kartoffel is a transformation of the Italian tartufo (truffle).^[7] The way each language named the plant encapsulates the impression it made and the route by which it was received when each culture first encountered it.

Parmentier’s name survives today in French cuisine as an adjective preceding dishes made with potatoes — Hachis Parmentier being the most familiar example.^[1] At the Sanssouci Palace in Potsdam, where Frederick the Great is buried, visitors still lay potatoes at his grave — a German tribute to the king who worked to spread the crop.^[10]

The logic with which Europe rejected the potato was singular: “This is food for beasts.” What dismantled that logic was not persuasion but hunger. Irish smallholders ate potatoes to survive; those potatoes grew the population; the growing population grew ever more dependent on a single crop; and in the end disaster struck. The gap between salvation and catastrophe was as thin as the vulnerability of a single variety.

The 4,000 potato varieties that Indigenous farmers in the Andes are keeping alive today are not merely a collection of plants. They are a biological memory in which 8,000 years of choices and failures have accumulated — insurance against a crisis that has not yet arrived. And the first to understand the value of that insurance was not Europe, but the people of the Andean highlands.
