The following contribution expands the current discussion on the status and function of the history of education at the methodological, or epistemological, level by introducing the perspective of a history of educational knowledge. This opens up a theoretical option for educational historiography that avoids the identification of history of education with history of a discipline, or the institutionalized knowledge of education and teaching. As a consequence, some history of education topoi -as the history of a discipline -can be called into question and practiced historically rather than educationally or morally.
