Question

In addition to fighting in the army how did European colony contribute to the war effort

Answer 1

At the start of World War I, European powers held vast colonies in India, Africa, and Asia. Colonies they frequently controlled with military force. Troops were often made up of local soldiers, who were sometimes used to fight against their own countrymen, but rarely against white men, and never in Europe.
