Ireland had a potato famine, caused by potato blight. It ran from 1845 to 1849. As a result of the dependency of people on potatoes at that time, millions died or emigrated, causing a major reduction in Ireland's population. Before the famine it was over 8 million. It still hasn't reached that level again, with the population now over 6 million.
