In this compelling book, highly acclaimed author and broadcaster Laurence Rees tells the definitive history of the most notorious Nazi institution of them all. We discover how Auschwitz evolved from a concentration camp for Polish political prisoners into the site of the largest mass murder in history - part death camp, part concentration camp, where around a million Jews were killed.

Auschwitz examines the mentality and motivations of the key Nazi decision makers, and perpetrators of appalling crimes speak here for the first time about their actions. Fascinating and disturbing facts have been uncovered - from the operation of a brothel to the corruption that was rife throughout the camp. The book draws on intriguing new documentary material from recently opened Russian archives, which will challenge many previously accepted arguments.

This is the story of murder, brutality, courage, escape and survival, and a powerful account of how human tragedy of such immense scale could have happened.
