Book excerpt: Based on a decade of research in over twenty archives, The Chronology of Revolution is an accessible and richly detailed work of historical and cultural analysis that fixes its gaze on the legacy of the Communist Party of Great Britain (CPGB). Communists anticipated that the party, formed in the world's first industrialized nation, would be in the vanguard of world revolution. Instead, the party never came close to matching the political power of the British Labour Party or continental Communist Parties in France or Italy and dissolved itself in 1991. In this book, Ben Harker draws on the ideas of Antonio Gramsci to argue that the CPGB, despite having great influence over British culture, never fully appreciated the importance of civil society to its political strength. Analysing party members’ efforts in fields such as science, journalism, the arts, broadcasting, and education, The Chronology of Revolution offers an alternative, radical history of Britain between 1920 and 1991 that draws out important lessons for the contemporary Left.
