World War one changed women's roles by giving them the ability to get other jobs other than working at home. Women were able to not only gain some of he rights as a man did but they were able to work if they wanted to. Typically women were expected to stay at home and take care of household things such as cooking, cleaning and taking care of the kid (s) but the war opened opportunities for women to get jobs and do things outside of the typical household.
