Most were desperately poor, and many were suffering from starvation and disease. They left because disease had devastated Ireland’s potato crops, leaving millions without food.

Detailed explanation-3: -Between 1845-52 Ireland suffered a period of starvation, disease and emigration that became known as the Great Famine. The main cause was a disease which affected the potato crop, upon which a third of Ireland’s population was dependent for food.

People were so dependent on potatoes that hundreds of thousands died of starvation in the mid-1840s when disease destroyed the potato crop. This tragedy is known as the Great Famine or the Irish Potato Famine.
