The total number of military and civilian casualties in World War I was about 40 million: estimates range from around 15 to 22 million deaths and about 23 million wounded military personnel, ranking it among the deadliest conflicts in human history.

The Chinese Labour Corps was a force of workers recruited by the British government in the First World War to free troops for front line duty by performing support work and manual labour. The French government also recruited a significant number of Chinese labourers, and although those labourers working for the French were recruited separately and not part of the CLC, the term is often used to encompass both groups. In all, some 140,000 men served for both British and French forces before the war ended and most of the men were repatriated to China between 1918 and 1920.
