Race and the Colour-Line addresses the foundational ideas about race and colonialism in Central and Eastern Europe (CEE) and reconnects them to the global manifestations that influenced them. Focusing on race and colonialism, this book indicates a shift in the global racial discourse - an understanding of the specificity of Polish racism that can transform and add to our understandings of race in the West. Drawing on archival resources - manuscripts, documents, and records - from Poland and other parts of Europe, the book offers a compelling theoretical and historical context of race-making in the so-called 'peripheral sphere', while outlining the ways in which colonialism has been framed specifically within the Polish-Lithuanian Commonwealth and its empire in the Atlantic world. Following a race-conscious social analysis, the significance and originality of this work lie in tracing the specificity of blackness in Europe, and the very particular, but often neglected case of black people in CEE. To chart all this commendably, premised on critical race studies, the author uniquely explores the everyday racialized experiences of people of colour from Sub-Saharan African descent living in contemporary Poland and brings to the fore the obscurities of race and racism in the country. Through ethnographic research, the author shows how these particular people perform multiple identities in their daily lives as part of the configuration of a racially complex society. The demonstration of the 'globality of racism' in this book examines the phenomenon of race beyond its usual context in the West, and as such will appeal to scholars from a range of disciplines including Sociology, Geography, Anthropology, Postcolonial, Polish, and Slavic Studies.
