how long did the potato famine last

The Irish Potato Famine, also called the Great Irish Famine, lasted from 1845 to 1852, approximately 7 years. The blight that caused the famine destroyed potato crops repeatedly during this period, with the most devastating years being 1845 to 1849. The famine caused mass starvation, disease, and emigration, with over a million deaths and about two million people emigrating during and shortly after this time frame.
