The potato and the Irish Famine of 1845 will forever be linked. But what's often overlooked is how deeply connected the potato was to British colonial policies during that time. To Britain it was a symbol of Irish backwardness. In the book Rot, a new history of Ireland's Great Famine is revealed, showing how the British Empire caused the infamous disaster. Author and historian Padraic X Scanlan paints a complex and compelling picture of the Irish Famine of 1845, in which the potato — and the blight — played but a part in a broader story of colonialism, capitalism, and collapse.
