This is an analysis of the impact of the collapse of communism in Eastern Europe and the former Soviet Union on the communist parties of Western Europe. Seven case-studies, covering the Italian, French, Spanish, Portuguese, Belgian, British and German parties, provide a comparative perspective. The conclusion assesses the range of responses to the dramatic events of 1989-91 and the likely future direction of the west-European communist movement. It is argued that, whilst it is no longer possible to talk of a coherent "family" of communist parties, various individual parties - some of them in revised form - may continue to prosper.
