Social injustice has become one of the social vices that bedevil Nigerian society. The level of social injustice currently prevailing in Nigeria is alarming, and the poor citizens are beginning to feel the impact in the level of discontent among the citizenry, as demonstrated by various uprisings against the state. The poems of Victor Ngiri's “One Nigeria” and Ikenna Omeje's “The Shadows of Ethnicism and Tribalism” are aimed at capturing these scenarios. A thematic analysis technique is employed to explore the central idea of the poems, while a Marxist theoretical framework is employed in the analysis of data. The findings drawn from the study show that modern poets have been able to use the tool of poetry to satirize the evils of social injustice prevalent in Nigerian society. Furthermore, the poets identify ethnicism and tribalism as one of the major causes of social injustice in Nigeria. Consequently, the poets advocate that for African society to be better than what it is, people should emulate the past African heroes, preach the gospel of altruism, and lend peace a voice.
