This course will introduce some of the main theories and theorists in the sociological study of religion developed in North Atlantic urban centers from the last half of the nineteenth century to the first decades of the twentieth century. The main contributions to the sociology of religions by Karl Marx (and his colleague and often co-author, Friedrich Engels), Emile Durkheim, Max Weber and W. E. B. Du Bois, are the focus of this course. These theorists developed such an influence that their methodological approaches are still tangible in today's sociological research on religion. The role of religion, particularly Christianity in the African-American community, cannot be overstated, thus the work by Du Bois on African American religion, which has been largely ignored, will be covered in this course.
