Lavrentiy Beria was a Georgian-born Soviet security official and politician who rose through the secret-police apparatus and became head of the NKVD in 1938. Under Stalin he exercised enormous power over state security, forced labour, deportations and wartime administration, and after 1945 he was also closely involved in the Soviet atomic project.
Simon Sebag Montefiore discusses Beria extensively in Stalin: The Court of the Red Tsar as one of the dictator’s inner-circle magnates. The record is included because the book is nonfiction and treats Beria as a documented historical figure; interpretations of personal motives and responsibility should be understood within the evidence and arguments presented by the historian.
