Relying on previously undisclosed confessions of former mafia members now cooperating with the police, Letizia Paoli provides a clinically accurate portrait of mafia behavior, motivations, and structure in Italy. The mafia, Paoli demonstrates, are essentially multifunctional ritual brotherhoods focused above all on retaining and consolidating their local political power base. A truly interdisciplinary work of history, politics, economics, and sociology, Mafia Brotherhoods reveals in dramatic detail the true face of one of the world's most mythologized criminal organizations.
