The Great Famine of 1845-52 was the most decisive event in the history of modern Ireland. In a country of eight million people, the Famine caused the death of approximately one million, while a similar number were forced to emigrate. The Irish population fell to just over four million by the beginning of the twentieth century.

Christine Kinealy's survey is long established as the most complete, scholarly survey of the Great Famine yet produced. First published in 1994, This Great Calamity remains an exhaustive and indefatigable look into the event that defined Ireland as we know it today.
