The Great Irish Famine (1845–1852)

Overview

The Great Famine (Irish: An Gorta Mór) was a period of mass starvation, disease, and emigration in Ireland from 1845 to 1852, triggered by repeated failure of the potato crop due to a blight caused by the fungus-like organism Phytophthora infestans.[1] The potato blight destroyed up to half the 1845 crop and roughly three-quarters of the crop in several of the following years; because a large share of the rural poor depended on the potato as their staple food, the failures produced famine on a scale that killed an estimated one million people and drove one to two million more to emigrate, reducing Ireland's population from roughly 8.5 million before the famine to about 4.4 million by 1901.[1]

Throughout the famine years Ireland continued to export large quantities of food — grain, butter, livestock, and other provisions — to Britain, even as its own rural population starved.[1] Henry George later cited Ireland as a central case against Malthusian explanations of poverty: the famine, in George's reading, was not a story of population outrunning the land's capacity to feed people, but of a land-monopoly system — dominated by rack-renting and largely absentee landlords — that left tenant cultivators with a single, blight-vulnerable subsistence crop while the rest of the island's agricultural output was exported to pay rent.[2] In Progress and Poverty (1879, Book II, ch. II, "Inferences from Facts"), George argued that "Ireland has never yet had a population which the natural powers of the country, in the existing state of the productive arts, could not have maintained in ample comfort," and that "even during the famine, grain and meat and butter and cheese were carted for exportation along roads lined with the starving," food that "went not as an exchange, but as a tribute — to pay the rent of absentee landlords."[3] Lars Doucet's Land is a Big Deal discusses George's use of Ireland as a case study for this argument (Ch. 5).[2]
