The Great Famine, also known as the Great Hunger (an Gorta Mór), the Famine and the Irish Potato Famine, was a period of mass starvation and disease in Ireland from 1845 to 1852. It constituted a major historical social crisis and had a significant impact on Irish society and history. The most severely affected areas were in western and southern Ireland—where the Irish language was dominant—hence, in Irish, the period was contemporaneously known as an Drochshaol, which translates to "the bad life" and loosely translates to "the hard times". Debate exists regarding nomenclature for the event, including whether to use the terms "Famine", "Potato Famine" or "Great Hunger".
Blight in Ireland
Before the arrival of Phytophthora infestans, commonly known as "blight", only two main potato plant diseases had been discovered. One was "dry rot" or "taint", and the other was a virus known popularly as "curl". Phytophthora infestans is an oomycete (a variety of parasitic, non-photosynthetic organism closely related to brown algae, and not a fungus).
In 1851, the Census of Ireland Commissioners recorded 24 failures of the potato crop going back to 1728, of varying severity. General crop failures, through disease or frost, were recorded in 1739, 1740, 1770, 1800, and 1807. In 1821 and 1822, the potato crop failed in Munster and Connaught. In 1830 and 1831, counties Mayo, Donegal, and Galway suffered likewise. In 1832, 1833, 1834, and 1836, dry rot and curl caused serious losses, and in 1835 the potato failed in Ulster. Widespread failures throughout Ireland occurred in 1836, 1837, 1839, 1841, and 1844. According to Woodham-Smith, "the unreliability of the potato was an accepted fact in Ireland".
Tory government
Historian F. S. L. Lyons characterised the initial response of the British government to the early, less severe phase of the famine as "prompt and relatively successful". Confronted by widespread crop failure in November 1845, Prime Minister Robert Peel purchased £100,000 worth of maize and cornmeal secretly from America with Baring Brothers initially acting as his agents. The government hoped that they would not "stifle private enterprise" and that their actions would not act as a disincentive to local relief efforts. Due to poor weather conditions, the first shipment did not arrive in Ireland until the beginning of February 1846. The initial shipments were of unground dried kernels, but the few Irish mills in operation were not equipped for milling maize and a long and complicated milling process had to be adopted before the meal could be distributed.
In addition, before the cornmeal could be consumed, it had to be "very much" cooked again, or eating it could result in severe bowel complaints. Due to its yellow colour, and initial unpopularity, it became known as "Peel's brimstone".
Whig government
The measures undertaken by Peel's successor, Russell, proved inadequate as the crisis deepened. The new Whig administration, influenced by the doctrine of laissez-faire, assumed that the market would provide the food needed. They refused to interfere with the movement of food to England, and then halted the previous government's food and relief works, leaving many hundreds of thousands of people without access to work, money, or food. Russell's ministry introduced a new programme of public works that by December 1846 employed a third or half a million people but proved impossible to administer effectively.
Charles Trevelyan, who was in charge of the administration of government relief, limited the Government's food aid programme, claiming that food would be readily imported into Ireland once people had more money to spend after wages were being paid on new public-works projects. Trevelyan also argued that the disappearance of small farms and the transfer of estates to new investors could produce a more satisfactory settlement of the country. This position connected relief policy with an expectation of social and economic restructuring, rather than treating the immediate provision of food as its sole objective.
