Nationalism, as a political ideology, has played a crucial role in shaping modern history, identity, and state formation. Nuruddin Farah’s Variations on the Theme of an African Dictatorship trilogy and Blood in the Sun trilogy provide a profound critique of nationalism’s potential for unity and its susceptibility to political manipulation. This paper examines how Farah portrays nationalism as both a unifying force and a mechanism of exclusion, oppression, and political control. Through the lens of characters such as Loyaan, Medina, Deeriye, Askar, and Duniya, Farah dissects different forms of nationalism civic, ethnic, cultural, and expansionist and their impact on Somali identity, statehood, and resistance. His novels highlight the paradoxical nature of nationalism: while it fosters solidarity, it also exacerbates tribalism, gender inequality, and authoritarianism. By juxtaposing revolutionary ideals with the oppressive realities of post-independence governance, Farah critiques the distortion of nationalist ideals and underscores the need for nationalism to be rooted in genuine unity and individual freedoms rather than authoritarian control.
