Mass population displacement affected millions of Europe’s civilians across the different theatres of war in 1914–18. At the end of the war, a senior Red Cross official wrote ‘there were refugees everywhere. It was as if the entire world had to move or was waiting to move’. Europe on the move is the first attempt to understand their experiences as a whole and to establish the political, social and cultural significance and ramifications of the wartime refugee crisis. Drawing on original research by leading specialists from more than a dozen countries, it will become the definitive work on the subject and will appeal to anyone who wishes to understand how governments and public opinion responded to refugees a century ago.
