Key vocabulary — Príomhfhocail

  1. 1 An Gorta Mór The Great Famine (literally 'the Great Hunger'). A period of mass starvation in Ireland from 1845 to 1852 caused primarily by the failure of the potato crop.
  2. 2 Phytophthora infestans The water mould (blight) that destroyed potato crops across Ireland from 1845. It spread rapidly in the wet climate and wiped out successive harvests.
  3. 3 Lumper potato The main variety of potato grown by the poor in Ireland before the Famine — highly susceptible to blight. Most poor families depended on it as their sole food source.
  4. 4 Conacre system The system by which poor farmers rented tiny plots of land, paying with labour. When the crop failed, they had no food and no money for rent.
  5. 5 Coffin ships The overcrowded, poorly provisioned emigrant ships on which many Irish people fled to America and Canada. Conditions were often fatal — many died on board.
  6. 6 Soup kitchens Government-run and charitable feeding stations set up in 1847 (Black '47). At their peak they fed over 3 million people a day, but were abruptly closed.

The Great Famine — key facts

1845–1852

  • CAUSE: Phytophthora infestans (potato blight) destroyed the potato harvest in 1845, 1846, and 1848. Ireland had no other food source for the poor.
  • SCALE: Ireland's population before the Famine: approximately 8 million. After: approximately 5 million (1.1m died of starvation and disease; 1.5m emigrated 1845–1851).
  • BRITISH POLICY: food continued to be exported from Ireland during the Famine. The government's commitment to 'laissez-faire' economics limited effective relief.
  • EMIGRATION: ships to America (Boston, New York) and Canada (Quebec). Those who survived became the foundation of large Irish-American and Irish-Canadian communities.
  • LONG-TERM IMPACT: Ireland's population continued to fall for over a century. By 1900 it was 4 million. Today Ireland has the smallest population of any country in Europe that was similarly populated in 1845.
  • LEGACY: Famine memorials in Dublin, New York, and cities worldwide. The Irish diaspora (estimated 70 million worldwide) traces roots to the Famine era.
  • ONGOING DEBATE: whether British government policy amounted to genocide or criminal negligence remains contested by historians.
