The idea of total war existed in all countries involved in World War I. For example, countries used rationing to determine how much food, rubber, gasoline, and other items each citizen could use during the war. In order to draft more soldiers into the military, many of the nations established a policy of mandatory conscription. Some countries also controlled public opinion during the war by using censorship to prevent discouraging news from reaching the public.

Explanation:

Rationing was a constant in all warring countries, especially the European countries, which were being destroyed by the conflict. The objective of rationing was to avoid the total shortage of products and to enable the government to control resources. Compulsory recruitment became a rule in Europe during the First World War. With compulsory recruitment, men were required to enlist in the army of their country and ensure that the country had enough soldiers. All warring countries create propaganda and censorship offices.  To reinforce national sentiment, to demonize the enemy, to raise the morale of troops and civilians with permanent "brainwashing": in connection with censorship, propaganda had a formidable development in World War I, becoming a real strategic weapon.
