During World War I, women took on new roles in the workplace and military due to large numbers of men being deployed to the front. Women worked in munitions factories, transportation, offices, and some served as nurses or soldiers. Their contribution of 40% of the production effort helped support the war. After the war, women argued that if they could work and fight, they deserved the right to vote as well. Some countries like Germany and England granted women suffrage in the aftermath of World War I in recognition of their expanded roles during the conflict.
