Discussing the concept of peace education, specifically from a Swedish perspective, this paper offers a rationale for the inclusion of peace education in school curricula throughout the world. Organized into three sections, the first section presents a historical background to current peace education efforts, and focuses on developments since World War II, especially within Swedish schools. The second section seeks to define the content of peace education, and includes a discussion of the intellectual history of war, the arms industry, human rights, developing nations, psychological problems, security policy, and peace and the environment. The third section discusses how peace education is currently put into practice in Swedish schools. An appendix contains an excerpt from a paper on peace education and a 25-item list of references.
