Have you ever thought about why a country’s borders are where they are? ‘Dividing up the World; the story of our international borders and why they are where they are’, is an utterly fascinating study of how borders have come about and the stories behind them. As well as unearthing tales and anecdotes relating to more familiar borders, the author also examines less well-known ones including the Drummully Polyp, the Scots Dike, the Medicine Line, the Gadsden Purchase, Neutral Moresnet, the Green Line, the Sand Wall, the Gambian ‘Ceded Mile’, the Caprivi Strip and an island that changes nationality twice a year. The result is a highly entertaining, meticulously-researched book, full of accounts of geography, maps, politics, colonialism, power, aggression and negotiation. After reading ‘Dividing up the World; the story of our international borders and why they are where they are’, you will never think of borders in the same way again.
