application/pdf 466396 bytes info:eu-repo/semantics/conferenceProceedings Key words: fundamentalism, extremism, Sunnis, Shiites, Ahmadiyya Quranists, Nigeria. 2023 Purpose: Nigeria is a complex society with a large number of different ethnic groups, within which religion has an extremely powerful influence. The author’s intention is to examine the thesis that, when it comes to Nigerian politics, the influence of religion is a direct consequence of the colonial rule of Great Britain and that the exact same influence of religion on politics in Nigeria has produced religious violence and political insecurity in the country. Design/Methods/Approach: In this paper, the methods of analysis, synthesis, hypotheticaldeductive method, methods of generalization, and concretization will be used. Findings: Religion plays an important role in Nigerian society as a complex and multidimensional phenomenon, with each religion proclaiming its belief to be the only right and true one. Hence, every religion aims to spread faith and protect religious identity, and as a result, a defensive attitude among members of the religious community appears, which can take the form of fundamentalism, extremism, or religious violence. Originality/Value: Given that the purpose of this research is the analysis of fundamentalism, from which extremism arises, in the paper, the authors analyze in detail the types of Shia and Sunni extremism, the extremism of the Ahmadiyya religious community, and the extremism of the Koranists in Nigeria. The authors conclude that with the help of an inadequate interpretation of sacred texts, fundamentalist groups appeal for general mobilization and seek support at the domestic and international level in order to achieve their aspirations, which are often manifested in the form of violence, sometimes against another religious or ethnic group, and sometimes against the state.
