This paper is aimed to analyze Toni Morrison忆s novel Beloved from the perspective of Trauma theory. By exploring the traumatic symptoms of main characters and the ways of recovering themselves from traumas, the author wants to expose the real aim of this novel. As an African-American writer, Morrison’s works show distinct political intention and cultural position. Morrison not only wants to disclose the hard -living environment of the blacks in the period of the ending of the slavery and the period of American southern reconstruction, but also hopes the blacks face the past bravely, recover from the trauma by love and union, construct their unique political and cultural identities, and create a brand-new future.
