48 dated and undated moments across ten thousand years: a mountain crop, an imperial technology, a colonial traveller, a famine warning and a modern food system.
A crop is made from altitude, frost and time.
Hunter-gatherers in the altiplano of southern Peru and northwestern Bolivia begin cultivating wild tubers of the Solanum brevicaule complex. The potato is not a single invention but a long collaboration between people, plants and mountain ecologies.

The Inca state scales up preservation, roads and food security.
As Tawantinsuyu expands, potatoes become part of a state economy that can move food, labour and armies across extreme terrain. The crop’s value is not only how much it yields, but how well it can be stored.

Governments, armies and hungry cities discover a high-yielding crop.
Prussian authorities begin promoting potato cultivation as a hedge against grain shortages. The crop’s reputation shifts from suspicious foreigner to useful instrument of state food policy.

A single pathogen exposes the politics of dependence.
A water mould, probably carried from the Americas, rots potato crops in the field and in storage across Belgium, the Netherlands, Prussia, France, England and Ireland.

Chemistry, breeding and markets rebuild the crop at industrial scale.
Improved transport and expanding markets turn seed potatoes into a traded commodity. Farmers can access new varieties, but they are also drawn toward the uniformity that makes large-scale production efficient.
