E. H. Carr was one of the most influential theorists of international relations, and his works, notably The Twenty Year's Crisis (1939), are widely read by students of the subject. He is generally regarded as a hard-nosed, right-wing political realist, but Charles Jones' study reveals him as a much more radical figure. By examining the political context in which he wrote, and the ruthless ways in which he sought to persuade his contemporaries in a period of national crisis, this book offers a radical reinterpretation of a major theorist of international relations.
