Dan Snow recreates a map of Europe on the beach in Blackpool to reveal the geopolitics of the continent as it stood on the brink of World War I. The sequence of crises that took place can seem murky to the uninitiated. Time and the recriminations of the parties involved have combined to make the events that led to war seem ambiguous and confusing. Now, using remarkable sand art, Dan brings his clarity of style and presentation to the subject, shedding new light on our descent into the war and unravelling the reasons behind a conflict that is fast receding in our collective memory.
