The Irish Famine
Between 1845 and 1852, Ireland experienced a period of mass starvation and disease known as the Great Famine, the Great Hunger, or simply the Famine. In Irish, it was called *an Gorta Mór*, and at the time, people in Irish-speaking areas—particularly the hardest-hit western and southern regions—referred to it as *an Drochshaol*, meaning "the bad life" or "the hard times." There is ongoing debate over which name is most appropriate: "Famine," "Potato Famine," or "Great Hunger." The worst year was 1847, remembered as "Black '47."
Before the famine, Ireland’s population was about 8.5 million. By 1901, it had fallen to 4.4 million. Roughly one million people died, and over one million emigrated. Between 1841 and 1871, the population dropped by 20–25%, with some towns losing as much as 67% of their people. From 1845 to 1855, at least 2.1 million people left Ireland—one of the largest exoduses from a single island in history.
The immediate cause was a potato blight that infected crops across Europe, leading to about 100,000 deaths outside Ireland and contributing to the unrest that sparked the Revolutions of 1848. But the scale of Ireland’s disaster had deeper roots: a system of absentee landlordism and a heavy dependence on a single crop. Initial British government relief efforts were helpful but limited, and a new Whig administration in London ended them, favoring a laissez-faire economic approach. Some British officials viewed the famine as divine punishment or a sign of Irish moral failings. Aid was later partially restored. Meanwhile, large amounts of food continued to be exported from Ireland during the famine. The British refusal to stop these exports—something it had done in earlier crises—became a major point of contention. This fueled anti-British sentiment, Irish nationalism, and the push for independence. Tens of thousands of families were evicted, a situation worsened by a rule barring anyone with more than a quarter-acre of land from receiving workhouse aid.
The famine is seen as a turning point in Irish history. It permanently reshaped the country’s demographics, politics, and culture, creating an estimated 2 million refugees and triggering a century of population decline. The memory of the famine became embedded in folk tradition, both in Ireland and among the diaspora. Strained relations with the British government grew worse, heightening ethnic and sectarian tensions and boosting nationalism and republicanism at home and abroad. When blight returned in 1879, the Land League boycotted "notorious landlords" and physically blocked evictions. This reduced homelessness and house demolitions, leading to far fewer deaths.
**Causes and contributing factors**
Ireland became part of the United Kingdom in January 1801 under the Acts of Union. The British government appointed the Lord Lieutenant of Ireland and the Chief Secretary for Ireland to hold executive power. Ireland sent 105 MPs to the House of Commons, and 28 Irish representative peers sat for life in the House of Lords. Between 1832 and 1859, 70% of Irish representatives were landowners or their sons. In the 40 years after the union, British governments struggled to govern a country that, as Benjamin Disraeli said in 1844, had "a starving population, an absentee aristocracy, an alien established Protestant church, and in addition, the weakest executive in the world." One historian counted 114 commissions and 61 special committees investigating Ireland between 1801 and 1845; all predicted disaster—rapid population growth, widespread unemployment, appalling housing, and extreme poverty. Lectures printed in 1847 by John Hughes, Bishop of New York, examined the political climate as a key antecedent cause.
**Landlords and tenants**
In the 18th century, a "middleman system" was introduced for managing landed property. Landlords’ agents, or middlemen, collected rents, ensuring landlords a steady income while leaving tenants vulnerable to exploitation. Middlemen leased large tracts on long leases with fixed rents, then sublet to tenants, pocketing any surplus. With little oversight, they split holdings into smaller and smaller parcels to maximize rent. Tenants could be evicted for non-payment or at a landlord’s whim.

Lore & Background
The proximate cause of the famine was the infection of potato crops by blight throughout Europe. The impact of blight on food supply caused 100,000 deaths outside Ireland, and influenced much of the unrest that culminated in European Revolutions of 1848. Longer-term reasons for the scale of the famine's impact included the system of absentee landlordism and single-crop dependence. Initial government actions to alleviate famine distress, which were constructive but limited, were ended by a new Whig administration in London that pursued a laissez-faire economic doctrine. Additionally, some members of the British government believed that the famine was divine judgement or that the Irish lacked moral character. Aid resumed only to some degree at a later stage. Large quantities of food were exported from Ireland during the famine, and the refusal of London to bar such exports, as had been done on previous occasions, was an immediate and continuing source of controversy. This controversy contributed to the exacerbation of the Irish issue in British politics, the intensification of anti-British sentiment, the intensification of Irish nationalism and the campaign for independence. Additionally, the famine indirectly resulted in the eviction of tens of thousands of households, a situation exacerbated by a provision that forbade access to workhouse aid for those possessing more than one-quarter acre of land.
Reader's Guide
The famine is considered a defining moment in the history of Ireland. Its effects permanently changed the island's demographic, political, and cultural landscape, producing an estimated 2 million refugees and spurring a century-long population decline. The population of Ireland on the eve of the famine was approximately 8.5 million; by 1901, it was 4.4 million. During the Great Hunger, roughly one million people died and over one million more emigrated, causing the country's population to fall by 20–25% between 1841 and 1871, with some towns' populations falling by as much as 67%. Between 1845 and 1855, at least 2.1 million people left Ireland, one of the greatest exoduses from a single island in history. For both the native Irish and those in the resulting diaspora, the famine became part of folk memory. Strained relations between many Irish people and the then ruling British government worsened further because of the famine, heightening ethnic and sectarian tensions and boosting nationalism and republicanism both in Ireland and among Irish emigrants around the world. When the potato blight returned to Ireland in the 1879 famine, the Land League boycotted 'notorious landlords', and its members physically blocked the evictions of farmers. The resulting reduction in homelessness and house demolitions led to a significant decrease in the number of deaths.
