This is only a partial answer: WWI led to the founding of the League of Nations, the forerunner of the UN, which had some declarations on freedoms around the world. WWII was, however, much more influential as it led not only to the birth of the UN but also to the drawing up of the Universal Declaration of Human Rights (and the birth of the concept of human rights). While the men were fighting on the front, the women kept the homes and the industries going.
Out of necessity, many women managed to work outside the home for the first time properly in industries and jobs that were previously closed to women. Thus there were women in factories, as bus drivers and conductors. Women were also farmers.
In most cases, however, the added freedom that women had during WWII came quickly to an end after the war when men returned home from the front and took over their former jobs.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
