How has race shaped Canada’s international encounters and its role in the world? How have the actions of politicians, diplomats, citizens, and nongovernmental organizations reflected and reinforced racial power structures in Canada? In this book, leading scholars grapple with these complex questions, destabilizing conventional understandings of Canada in the world. Dominion of Race exposes how race-thinking – normalizing racial differences and perpetuating them through words and actions that legitimize a discriminatory system of beliefs – has informed priorities and policies, positioned Canada in the international community, and contributed to a global order rooted in racial beliefs. Four themes develop throughout the volume: the relationship between empire, identity, and liberal internationalism; the tensions between individual, structure, theory, and practice; the mutual constitution of domestic and international spheres; and the notion of marginalized terrain and space. While the contributors reconsider familiar topics, including the Paris Peace Conference and Canada’s involvement with the United Nations, they also enlarge the scope of Canada’s international history by subject, geography, and methodology. By demonstrating that race is a fundamental component of Canada and its international history, this important book calls for reengagement with the histories of those marginalized in, or excluded from, the historical record.
