Postcolonial feminism or third-world feminism is a current movement that illustrates the way women of the colonized countries suffer from double marginality practiced by native patriarchs and imperialists. In this regard, Joseph Conrad’s Heart of Darkness and E. M. Forster’s A Passage to India have been selected to be investigated and discussed from the postcolonial feministic point of view. Thus, the present study examines female voicelessness and double colonization of third-world women through the postcolonial feministic perspectives and texts of Gayatri Chakravorty Spivak. Spivak’s theories on subalternity will be applied to the selected novels. The main purpose is to investigate the role of women in the postcolonial contexts and to have a deep look at postcolonial feminism by the help of the theories of Spivak.
