First published in 1981, this book reassesses the case of Sacco and Vanzetti, two Italian immigrant anarchists living in Boston in 1920. The pair were accused of a payroll robbery and the murder of two guards for which they were arrested and, after a long trial based on inadequate and prejudiced evidence, executed in 1927. In 1977, on the fiftieth anniversary of their deaths, the Commonwealth of Massachusettes issued a proclamation which acknowledged a miscarriage of justice. "The Black Flag "provides an account of the controversial trial and a re-evaluation of the celebrated case of the Commonwealth s decision. Brian Jackson puts the trial in the social context of the period and exposes the nature of anarchism by looking at the lives of two of its exponents, resulting in a moving exploration of a series of events that continue to trouble the conscience of America.".
