This article presents the conceptual foundations of the Education for Peace (EFP) integrative curriculum, reviews its contents, and briefly describes its impact on students, teachers, staff and parents/guardians in Bosnia and Herzegovina. The curriculum was developed in 2000, first employed in six pilot schools and then implemented in 112 primary and secondary schools in Bosnia and Herzegovina as well as in a few schools in North America, thus far involving thousands of educators and tens of thousands of students. The curriculum is being published in nine volumes covering core aspects of peace education. This article reviews the curriculum's comprehensive and inclusive pedagogical approaches and unique conceptual formulation, which defines conflict as the absence of unity and unity as the main prerequisite for peace. The curriculum integrates insights from a wide range of disciplines on peace and education, including education, peace studies, conflict resolution, political science, law, religion, sociology, psychology and history. Within this integrative approach, each volume addresses one or more aspects of peace and peace education, drawing from the latest developments in the field and from lessons learned in the implementation of the EFP program. The final part of the article includes several first-hand statements attesting the efficacy of the EFP program.
