In this study, we analyse 126 secondary pupils' responses to national test questions designed to make them think and care about the history of national minorities in Sweden. Using a mixed method approach we find that historical thinking and empathy as caring are tightly interlinked in the responses. In particular, the cognitive act of corroborating historical sources about the treatment of minorities is linked to historical empathy as caring -- while sourcing seems like a separate process. We also find that pupils struggle to link the past to the present and the future more than they do with sourcing and corroboration. Engaging with the past of discrimination of minorities makes pupils take critical positions beyond established dimensions of historical thinking. Our findings highlight how we need to better understand how to scaffold pupils' practical knowledge, skills and attitudes in ideologically and emotionally charged issues.
