This article examines the dysfunctions of religion in politics and its negative impact on society. Through a functionalist approach, the author explores religion as a social structure with both positive and negative functions. While acknowledging the significant existence of religion in society, the focus is on its political capabilities and the negative impact it has had historically. The paper discusses the influence of religion on conflicts, wars, barriers to political change, and segmentations. Using evidence from previous literature and new research, the author argues that religion can act as a barrier to pluralism and hinder political development in religious societies. By analyzing the political functions of religion, the article highlights the negative effects of religious beliefs when mixed with politics, leading to disintegration and division. Finally, the author urges scholars to examine critically the functions of religion beyond political religion and fundamentalism to understand its impact better on society
