Life in post-colonial Kenya is characterized by various aspects of corruption and disintegration resulting from the hegemony of the kleptocratic government of Kenya. Based on Antonio Gramsci's discussion of the notion of hegemony, and out of Aschcroft, Griffiths, and Tiffin's definition of the process of decolonization, the paper sheds light upon the ignominious status of Kenya after independence and the efforts of the Kenyan masses to resist and regain their stolen country. Through Ngugi Wa Thiong's Devil on the Cross, the research exposes the exploitation policies of the native rulers in postcolonial Kenya and their role in suppressing the hopes and volitions of the miserable people. As a Kenyan writer, Ngugi Wa Thiong'o devotes most of his works for criticizing the Kenyan leaders' rule and shows their intractable intentions to spread different forms of corruption all over Kenya on account of realizing their illegal objectives.
