What is the ethnic breakdown of World War 1?

World War I involved a diverse array of ethnic groups, primarily from Europe, but also included colonial troops from Africa, Asia, and the Americas. The major powers included the Allies, mainly composed of British, French, Russian, Italian, and later American forces, and the Central Powers, which included Germans, Austro-Hungarians, and Ottomans. Various ethnic minorities, such as Poles, Czechs, and Serbs, also played significant roles, often seeking independence or autonomy from larger empires. Additionally, colonial troops from regions like Africa and India contributed significantly to the war effort, reflecting the global impact of the conflict.
