Potato blight was the proximate cause of the Irish Potato Famine of 1845-1849, but there were many contributing causes including the high dependency on this food staple, the harshness of British rule, the passage of laws that prohibited Irish Catholics from owning land, absentee landlords, dire poverty, and the subdivision of holdings that made the raising of any crops other than potatoes nearly impossible. As the famine took its toll, more than 1.5 million people would die of starvation in Ireland and another 1 million would emigrate to other countries
