The Edge of the Plain: How Borders Make and Break Our World

Open or closed, borders shape our lives, and even our chances of life. Inspired by his Scottish familyâ€s history of migration, James Crawford investigates the origins and effects of borders. His quest takes him to the British Museum to decipher an ancient Mesopotamian boundary marker; to Romeâ€s northernmost frontier in Scotland; to Arctic Norway, where the land of the Sami stretches across nations; and to Donald Trumpâ€s Mexican wall.
