Why did over a million people Irish people die of starvation and disease, and more than two million leave that country during roughly six years in the mid-1800s? The label "potato famine" doesn't begin to explain a crisis that was hundreds of years in the making, and one that happened in the midst of plenty. "Ireland's Great Hunger and The Irish Diaspora," narrated by actor Gabriel Byrne, explores the history, culture, and politics that lead to mass starvation, eviction, disease, and death in 19th century Ireland, and the lasting global legacy of that tragic event.
