The Irish Famine of 1846-50 took as many as one million lives from hunger and disease, and changed the social and cultural structure of Ireland in profound ways. The Famine also spurred new waves of immigration, thus shaping the histories of the United States and Britain as well. The combined forces of famine, disease and emigration depopulated the island; Ireland's population dropped from 8 million before the Famine to 5 million years after.
It was a strain of Phytophthora infestans. Irish potato famine pest identified. Scientists have used plant samples collected in the mid-19th Century to identify the pathogen that caused the Irish potato famine. A plant pest that causes potato blight spread to Ireland in 1845 triggering a famine that killed one million people. DNA extracted from museum specimens shows the strain that changed history is different from modern day epidemics, and is probably now extinct.
