A staple crop: Potatoes grew readily in Irish soil and had become a staple of the diet for a growing populace. Within the first 40 years of the 19th century, Ireland’s population had taken off -- from an estimated 5.2 million in 1801 to 6.7 million in 1820 and 8.1 million in 1840. (See Irish census records.)
Everything changed with a blight caused by a plant pathogen still the focus of academic research. Conditions on the island, specifically, heavy rains in the summer of 1845, made matters worse.
In September, the first sign of potato blight appeared, wrote historian Jay P. Dolan in The Irish Americans (Bloomsbury Press; 2008). The problem was more widespread by October.
The political philosophy: A humanitarian disaster was clearly unfolding in Ireland, but key British politicians believed in a laissez-faire economic philosophy, which stated that there should be little interference with the market forces of supply and demand. Charles Trevelyan, head of Great Britain's treasury and in charge of famine relief, was a firm adherent, and he also saw the crisis as an act of God. Dolan recounts that Trevelyan described the famine as a “direct stroke of an all-wise and all-merciful Providence” that “laid bare the deep and inveterate root of social evil” plaguing Ireland.
The response: Even so, the British government had to intervene. In November 1845, Great Britain’s prime minister, Sir Robert Peel, made three decisions, writes Robert Kee, historian and journalist, in the book, Ireland: A History (Little, Brown & Company; 1980). Peel ordered a supply of maize for Ireland and wanted to sell it at low cost. But this food was brought in not primarily "to be eaten immediately by people who were beginning to starve but only as a gently-applied economic lever." The corn would be released for sale only when the government decided that food prices were too high.The great hunger: In 1845, the failure of the potato crop was not a total loss because a portion had been harvested before the blight, Dolan writes. But in 1846 the whole crop failed. Accounts of the time describe entire families found dead in their homes. Others were evicted and roamed the countryside. While many fled on boats bound for the U.S., some devised a different strategy: They committed theft in the open, in hopes of being arrested and put in jail or sent to a penal colony in Australia, according to Joseph R. O’Neill in the book The Irish Potato Famine. (Abdo Publishing; 2009).
As part of a U.S. effort to alleviate the crisis, Congress in 1847 authorized the USS Jamestown and the USS Macedonian to transport food donated by Americans to Ireland and to western Scotland to address the neighboring Highland Famine. "Captain Robert B. Forbes, who brought the relief in Jamestown, made a return visit to Ireland twenty years later and met there young men and women named Jamestown and Macedonian," according to the Naval History and Heritage Command website.
The impact on the U.S.: Well before the famine, there had been a flow of immigrants from Ireland bound for the Colonies. Dolan writes that shipping agents promoted America as the "garden spot of the world." But during and after the famine, a green tide washed ashore -- an estimated 1.5 million fled to the United States. Today, roughly 35 million U.S. residents claim Irish ancestry.
