In the 1840s, a catastrophic famine brought about the decimation of Ireland’s poor and the exodus of millions from the island. This major, ground-breaking documentary, narrated by Liam Neeson, explores the famine’s international origins and development in Europe, Britain and Ireland and charts its long-term legacy as it plays out for much of the century that follows. Today the Irish famine is recognised as the worst humanitarian disaster of the 19th Century but what is less recognised is that the crisis impacted far beyond Ireland’s shores. The story of the Blight pathogen that killed the potato crop, starts in the Andes of South America and then reaches into the heart of northern Europe where the collapse of potato crops causes the deaths of 100,000 people adding further fuel to social tensions that lead to Europe’s year of revolutions in 1848.
