This article traces the hidden race-religion constellation in Europe. The term “race-religion constellation” refers to the connection or co-constitution of the categories of race and “religion.” Specifically, the term “race-religion constellation” is used to refer to the practice of classifying people into races according to categories we now associate with the term “religion.” This calls for a consideration of European history and forms of racism in Europe, such as anti-Semitism and Islamophobia. This article aims to provide an alternative non-secularized or (...) biological account of the origins of the socially constructed category of race in Europe. The alternative story begins in the sixteenth century, when the category of “religion” as a means for classifying peoples was both constructed and politicized. In tracing this alternative story, this article seeks to outline a framework for a critical philosophy of race focused on a European religion line that intersects with Du Bois's color line. (shrink)
