This study aims to investigate how history teachers relate to whiteness and the whiteness norms in their teaching. The material mainly consists of qualitative interviews with history teachers who are active in lower secondary schools in Jönköping County. The questions are based on how the teachers reason regarding the whiteness norms, how they work with these in their teaching and how the teachers appraise that these norms affect their pupils' identity creation and history consciousness. The results show that a large part of the respondents show an uncertainty when they talk about the whiteness norm, this stems from a lack of understanding for the meaning of the concepts. It also appears that some respondents have reflected on the whiteness norms in their teaching before, however, a difference can be seen in the respondents’ answers depending on how or if they have reflected on the subject of whiteness norms or not. The respondents handle the uncertainty in different ways, among other things by being or not being a killjoy (a person who decides whether they should bring down the mood in the room through confrontation or not). In the conversation with the respondents, they describe how their view of the students' identity and that it can vary depending on whether the pupil belong or does not belong to the whiteness norm.
