An excerpt from The Potato, a 1917 book by Arthur W. Gilbert.

Gilbert discusses the origins of the potato and its transfer from the Americas to Europe. The potato originated in multiple places, but was first cultivated in Peru by the Incas some time between 8,000 BCE and 5,000 BCE. In 1589 CE, Sir Walter Raleigh introduced the potato to Ireland, where it became a major staple crop.
