This book investigates the historical development and theoretical underpinnings of race and ethnic relations as academic fields of study. John Rex, a noted sociologist, draws upon a wide range of scholarly literature to present a comprehensive overview of the major theoretical frameworks that have shaped our understanding of intergroup relations, conflict, and social stratification. The work examines the evolution of thought from early sociological perspectives to more contemporary analyses, providing a critical assessment of their strengths and limitations in explaining persistent racial and ethnic inequalities.

This work is recognized as a foundational text in the sociology of race and ethnicity, offering a rigorous and comprehensive survey of the field's theoretical landscape. Scholars often cite Rex's ability to synthesize complex ideas and provide a critical historical perspective on how concepts of race and ethnicity have been conceptualized and debated. The book is valued for its detailed examination of competing theories and its contribution to understanding the persistent challenges of racial and ethnic inequality.
