Internal conflicts continue to grow in Nigeria, despite scholarly studies that prescribe empirical solutions to their abatement. This study therefore examined conflict from the theoretical paradigm of Samuel Huntington's thesis with the aim of determining its applicability with identity-based conflicts in selected states such as Plateau, Anambra, and Osun States. To achieve this, objectives raised were to: i. analyse the tenets of Huntington’s Clash of Civilisation thesis; ii. identify the dynamics of the major types of conflicts in Nigeria; iii. frame conflicts in Nigeria using Huntington's thesis as a paradigm; iv. assess the relevance of Huntington's 'Clash of Civilisations' thesis to selected contemporary identity conflicts in Nigeria; and v. examine how Huntington’s thesis can be adequately used to mitigate contemporary identity conflicts in the study area. The study employed survey and descriptive research design, using such instruments as questionnaire, and interviews with a cross-section of 400 respondents from the localities mentioned above. It was found that, in spite of the fact that civilisation is a cultural entity, the fundamental avenue through which conflicts are and will be expressed in this new world and in Nigeria is not primarily ideological or mainly economic, but cultural, with the conflicts being both inter- and intra-civilisation. Also, more than 66.70% of the respondents (particularly among the academics interviewed) pointed out that identity-based conflicts in Africa and Nigeria predated the two world wars and the Cold War. An average of 86.56% of the respondents under the third research objective agreed with Huntington that the farther one goes from his sphere of affiliation, the wider his sphere of affiliation. This suggests that identity is, to a Nigerian, a strong psycho-social garment by which he defines himself or herself. Furthermore, inadequate social structures, resources
