During the First World War, the United States was in total warfare efforts. Every person had to help in contributing to the war. However, this doesn't necessarily mean that everyone needed to fight. The country needed to continue to fund its troops and support the war financially while soldiers were fighting. The United States relied on organizations to support war efforts. Women joined organizations such as the Committee on Public Information in order to educate people about the war. This committee additionally promoted nationality. In addition to working for committees having to do with education, women worked in all sorts of positions. Many women became YWCA members and went overseas to help soldiers. This was the first time in history that women of all classes were working together to help the war efforts. Upper-class women founded many voluntary war organizations while middle and lower-class women worked in these organizations by working as nurses or by filling in the jobs of men.
