The Great Famine, also known as the Great Hunger (Irish: an Gorta Mór [ənˠ ˈɡɔɾˠt̪ˠə ˈmˠoːɾˠ]), 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".
The worst year of the famine was 1847, which became known as "Black '47". 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.
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.
Why this event still matters
Historical incidents shape the rules that protect people today — building codes, evacuation policy, warning systems and inspection regimes almost always trace back to a specific disaster. Studying Great Irish Famine alongside current events is how preparedness improves.
