Focusing on the Greek Civil War (1946-1949), the last major conflict in Europe before the end of the Cold War, this study examines the political prisoners whose fate encapsulates the dramatic conflicts and contradictions of that dark era. New sources such as prisoners' letters, memoirs, and official reports, the author describes the life of the prisoners and the effect the prison administration and the prisoners' collective had on their personality. Drawing comparisons to political prisoners in Germany and Spain, the author sheds new light on our understanding of the ideologies and policies and their effect on individuals, which marked European history in the 20th century.
