Kant's 200-year-old essay is considered in light of its enduring impact on peace studies, the creation of the United Nations, and the implementation of a new world order based on lasting peace. Through a detailed analysis of its content and the cross-examination of various sources, it is suggested that the reputation of Perpetual Peace is not undeserved: while stressing the importance of fundamental principles applied to world affairs, it also provides realistic steps towards conflict resolution. Most importantly, the present study attempts to show how Kant's view of religion's role in human life, based on his critical philosophy, serves as the underlying catalyst of his apparently secular considerations.
