Ten historians from 10 countries give a brief history of the first world war through a global lens. Using original news reports, interactive maps and rarely-seen footage, including extraordinary scenes of troops crossing Mesopotamia on camels and Italian soldiers fighting high up in the Alps, the half-hour film explores the war and its effects from many different perspectives. You can watch the documentary in English, French, German, Italian, Spanish, Arabic or Hindi thanks to our partnership with the British Academy.
