What crop failure caused the Irish Famine?

The crop failure that caused the Irish Famine, also known as the Great Famine or the Potato Famine, was the potato blight. The blight was a fungal disease that attacked the potato crops and destroyed them, leading to a severe food shortage in Ireland. This, in turn, caused widespread hunger, disease, and death throughout the country, as many people depended solely on potatoes as their primary source of food. It is estimated that around one million people died from starvation and diseases related to the famine, while millions more emigrated from Ireland in search of food and a better life elsewhere.
