The potato was the first domesticated vegetable in the region of modern-day southern Peru and extreme northwestern Bolivia between 8000 and 5000 BCE. It arrived in Europe sometime before the end of the 16th century by two different ports of entry: the first in Spain around 1570, and the second via the British Isles between 1588 and 1593. There is also potato and dill recipes evidence from stone tools of potatoes suggesting evidence of potatoes existing as far back as 3400 BC.
Archeological evidence also shows that throughout the formative period from 1500 BC to 500 BC and Tiwanaku period in the Andes, potatoes and tubers became increasingly popular as a crop and food. Boiled and steamed potatoes and tubers replaced soups throughout the formative period. Aside from these remains, in the Peruvian archaeological record, the potato was uncovered as a design influence of ceramic pottery in the Altiplanos, often in the shape of vessels. In the Altiplano, potatoes provided the principal energy source for the Inca Empire, its predecessors, and its Spanish successor. Andean people prepared their potatoes in a variety of ways, such as mashed, baked, boiled, and stewed in ways similar to modern methods. The Andean people also prepared a dish called papas secas, which was a process that involved boiling, peeling, and chopping. Columbian Mapuches, “specially in the southern and coastal Mapuche territories where maize did not reach maturity”.
Sailors returning from the Andes to Spain with silver presumably brought maize and potatoes for their own food on the trip. Europeans in South America were aware of the potato by the mid-16th century but refused to eat the plant. For the Spaniards the potato was regarded as a food for the natives: the Spanish conquerors speak most favourably of the potato, but they recommend it especially for the natives who have to do the heaviest jobs. The potato first spread in Europe for non-food purposes. It was regarded with suspicion and fear due to it being a member of the nightshade family. Europeans assumed its resemblance to nightshade meant that it was the creation of witches or devils.
At first it was mostly used as fodder for livestock or to feed the starving. The Spanish had an empire across Europe and brought potatoes for their armies. Peasants along the way adopted the crop, which was less often pillaged by marauding armies than above-ground stores of grain. In France, at the end of the 16th century, the potato had been introduced to the Franche-Comté, the Vosges of Lorraine and Alsace. The potato had a large effect on European demographics and society, due to the fact that it yielded about three times the calories per acre of grain while also being more nutritive and growing in a wider variety of soils and climates, significantly improving agricultural production in the early modern era. Despite this it took a while to catch on.
It is generally believed that potatoes entered Africa with colonists, who consumed them as a vegetable rather than as a staple starch. Shipping records from 1567 show that the first place outside of Central and South America where potatoes were grown were the Canary Islands. In higher regions of Rwanda, potatoes have become a new staple food crop. Recently farmers have developed the potato as a cash crop after introducing several new varieties brought back by migrant laborers from Uganda and other varieties from Kenya. The potato diffused widely after 1600, becoming a major food resource in Europe and East Asia. Following its introduction into China toward the end of the Ming dynasty, the potato immediately became a delicacy of the imperial family. In India, Edward Terry mentioned the potato in his travel accounts of the banquet at Ajmer by Asaph Khan to Sir Thomas Roe, the British Ambassador in 1675.
