The document summarizes the Irish Potato Famine that occurred from 1845 to 1852. It was caused by a potato blight that destroyed the potato crops, which the Irish population relied on for food and income. As a result of the potato famine, over 1.5 million Irish people died of starvation or disease and many families lost their homes, jobs, food and money. The famine caused massive emigration from Ireland and is still commemorated today for its devastating impact on the Irish population and culture.
