The concept of "Grief and Trauma" in Walt Whitman's renowned poem "O Captain! My Captain!" and its relevance as a voice of political ethos in America are examined in this study(Dumitrica, 290). The goal of this research is to dive into Whitman's reasons for portraying loss and suffering, the problems he attempts to solve, the techniques he utilizes, and the influence on readers. This research provides insight on how Whitman's lyrical representation of grief and trauma works as a commentary on the socio-political milieu of his day by viewing the poem through the prism of political ethos (Walter and Kenneth 2023).The study opens by emphasizing the significance of comprehending the historical background around the production of "O Captain! My Captain!" as well as Whitman's personal connection to the events he laments. It then goes on to examine the underlying sorrow and trauma issues that Whitman is attempting to address in the poem, particularly the aftermath of the American Civil War and President Abraham Lincoln's assassination(Greenwood, 87). This analysis' technique is based on literary theory, namely the examination of sorrow and trauma in literature. The research reveals the deep-rooted influence of loss and tragedy on both the person and the nation as a whole by evaluating the poem's structure, language, and imagery, as well as the emotions portrayed. The poem is both a vehicle for national grieving and a call to action, calling Americans to confront their common pain and work towards healing and togetherness(Haddad, 78).

Whitman presents a striking reflection on the human capacity to survive and heal via his lyrical language, while emphasizing the necessity for political and cultural reform in the face of tremendous loss
