What impact did the Great Famine have on the population of Ireland?
The Great Famine had a tremendous impact on the population of Ireland. It dropped from about 8.4 million to 6.6 million in just seven years. This decline in population size was caused both by death (about a million people) and by emigration (about 2 million people).

The Great Famine or Irish Potato Famine began in 1845. The cause of the famine was a plant fungus that infected potato crops and ruined both the leaves and roots of the potato plant. In Ireland, potatoes were the most commonly cultivated plant since they were easy to grow and, at the same time, they were the main part of the diet. For these reasons, the shortage of potatoes had terrible consequences for the population of Ireland leading to death and emigration.
