This study aims at analyzing collective trauma and post-traumatic stress disorder in the novel Unresolved Tears. Trauma can be manifested in different form, and in all forms, it is fear of something bad not happen or inability to recover from something bad happened. It is the part of human life though the extent varies due to the socio economic and family backgrounds the survivors’ belonging to. This paper explores trauma in the novel Unresolved Tears-an Amharic novel. Characters in this novel undergo various traumatic experiences caused by starvation, civil war and maladministration which caused post-traumatic stress disorder upon them. The interpretation is based on Cathy Caruth’s concepts of double nature of trauma. The result of this research is expected to be useful and helpful for those who read this paper in offering supportive information about the selected novels, and would hopefully motivate other researchers to do further study in the area.
