As postcolonial criticism develops, theorists agree that the role of feminism in postcolonial practice is crucial. Furthermore, these two theories clearly have the same goals. On the one hand, the main goal of both is to reveal traditional power structures, both patriarchal and imperial. On the other hand, both feminism and postcolonial criticism aim to show how writers challenge each other's forms of authority. The main concerns of postcolonial criticism concern the formation of the canon, the phases through which imperialism and decolonization have passed, as well as the way in which these processes are expressed in literature. Furthermore, criticism is also about modes of resistance within literary works, such as rewriting traditional concepts and creating voices in opposition. All these questions become the matrix and concern of feminist criticism. Last but not least, the reference to the concept of diversity is also fundamental for feminism. For many women, the writing process is an expression of themselves, allowing them to “free themselves from the shackles” and strive for greater autonomy. The twentieth century gave rise to women's efforts to fight for their rights in the Western world. In the 1940s they were relatively emancipated, as they perceived encouragement to enter the world of work. There they could enjoy relative independence and felt responsible. They demonstrated that they could be "effective workers", but at the end of the Second World War they had to face new demands: having to give up their jobs to males returning from the war ("Feminism"). They were and felt out of place, everyone expected them to take care of their home instead. ...... middle of paper ......, Eadaoin. “Colonialism in Margaret Atwood's Outcrop.” April 12, 2003.Aspenlieder, Erin. “Tips for Surviving 'Atwood': Tackling the Complexities of Wilderness Celebrity.” Studies by Margaret Atwood. 3.1 (September 2009): 3-11.
