From Chronicles:
ShareSometimes great matters depend upon… vegetables. Ancient civilization was founded on the simple discovery that grasses could become grains, reliable and storable, allowing the emergence of fixed Fertile Crescent cities with rulers and philosophers. But vegetables can also yield disaster. The failure of the Irish potato crop in the mid-1840s not only brought terrible suffering to that island but has blighted Anglo-Irish relations ever since. Few other episodes have left such a toxic aftertaste, with over 100 memorials around the world and countless cultural references.
Canadian historian Padraic X. Scanlan has Irish antecedents, and generally left-of-center views. Still, he writes a careful analysis of an episode that is far from England’s finest hour. He has steeped himself not only in the cultivation, mythology, and natural history of the potato, but also in the cultural, economic, industrial, mercantile, and political currents which together heaped horrors on the Irish. He shows that what is often portrayed as a medieval-style catastrophe was in fact a modern one, a predictable product of the dynamic 19th century—and, furthermore, offers insights for our world regarding economic insecurities, environmental destruction, and ever-evolving pathogens.
Sometime in 1844 or 1845, a cargo of seed potatoes from America was offloaded somewhere in Europe. Unfortunately, that cargo contained an unobtrusive mold called Phytophthora infestans, which launched itself onto the Old World with alacrity. Potato crops from Spain to Sweden were affected, causing dearth and deaths, but the direst effects were felt in Ireland, where the population was uniquely dependent on the potato. In 1841, there were some 8.2 million people in Ireland; by 1851, that number decreased to 6.5 million, through death by starvation or disease, or forced emigration. Such was the culture shock that for almost a century afterwards the population of Ireland would continue to decline. The Irish government still issues annual warnings to farmers about the likelihood of blight.
Although Ireland had much fertile land and was famous for dairy and meat products, millions had been perilously reliant on the potato as early as the 1730s. There had been crop failures before; in 1740–41, the harvest was ruined by weather, and 300,000 died, a proportionally higher number than would die during the famine. Since its arrival in Tudor times, the potato had proved its worth as a cheap, easily cultivated, and highly nutritious staple. Grown and eaten close to home, the potato was largely insulated from market vagaries that were just becoming important with the rise of industry and commodity capitalism. Landlords encouraged it because it could feed more workers on less land, leaving acreages open to more lucrative grain or livestock. (Read more.)
