Controversial issues are often regarded as abundant in history education. Most topics can be regarded as controversial in one way or another. The purpose of this article is to analyse the way history teachers in Swedish lower secondary schools relate controversial issues to a particular view of the nature of the subject of history. By analysing statements from six teacher interviews which centred on the risks and opportunities associated with teaching about controversial issues, the authors were able to see a clear relation between views on controversial issues and views on the nature of history as such. The teachers' reactions to the introduction of controversial issues, whether introduced by the teacher or by the students, was in many cases directly related to a specific view of the subject itself and its epistemological nature.
