Teaching introductory sociology is one of the primary means by which sociologists mobilize knowledge. Ongoing critical reflection on the content of sociology textbooks is therefore an important disciplinary enterprise. The current critical moment in which many nations, institutions, and publics face a reckoning with their historic and current relationships with Indigenous peoples presents sociologists with the opportunity to examine how Indigenous peoples, histories, and perspectives are to be found in these pedagogical materials. Drawing on Critical Indigenous scholarship that "disrupts the certainty of disciplinary knowledges[']" concept of "connected sociologies," we examine the state of inclusion of Indigenous content in introductory sociology curriculum. To achieve this, we conducted a content analysis of 10 of the top-selling English-language Canadian introductory sociology textbooks, and we drew directly from interviews with Indigenous scholars. By introducing the literature on solidarity and allyship in the final section, we conclude with teaching and learning actions to incorporate in sociology courses.
