Over the course of a century, from 1918 to 2018, the First World War slowly blurred in the European popular imagination, often considered a tragic but monochrome European conflict. In the process, the Tirailleurs sénégalais, the sepoys of the British Indian Army, the men of the South African Native Labour Corps, the Chinese Labour Corps, and soldiers and auxiliaries from other parts of the world‚ were erased from historical memory. Also seemingly lost was an understanding of the conflict’s global scope and impact. By 1915, the Western Front, the front lines themselves, but also the support and supply zones behind them, constituted some of the most ‘international’ places to have ever existed. As late as 2014, historians across the world set out to use the centenary of the conflict to recover those lost stories. This keynote considers how successful those efforts have been, asking if, in 2026, the conflict is any better understood as the world’s war—a shared history.
