The role of women in Western society has changed dramatically over the centuries, from the repression of ancient Greece to the relative freedom of women living in Medieval France. The treatment of women has also differed from civilization to civilization even at the same period in history. Some societies such as Islamic ones have treated women much like property, while others like ancient Egypt have allowed women to have great influence and power. This paper will trace the development of women's rights and powers from ancient Egypt to late medieval France and explore their changing political, social and economic situation through time. All the various means women have used to assert themselves show the different ways they have fought against repression and established themselves in authority.
