World War I changed women’s roles in the United States since women replaced men in the workforce.
During WWI (1914-1918), large numbers of women were recruited into jobs that were carried out by men who had gone to fight in the war. Furthermore, new jobs were created as part of the war effort, for instance in munitions factories.
As a result of the increasing demand for weapons, the munitions factories turnt into the largest single employer of women during 1918.
