The first definitive history of the Nazi concentration camp system, KL will remain an essential read for years to come.

It is hard to imagine that Nik Wachsmann's superb book, surely to become the standard work on Nazi concentration camps, will ever be surpassed. Based on a huge array of widely scattered sources, it is a gripping as well as comprehensive and authoritative study of this grim but highly important topic

This is the fullest and most comprehensive history of the Nazi concentration camps in any language: a magnificent feat of research, full of arresting detail and cogent analysis, readable as well as authoritative: an extraordinary achievement that will immediately take its place as the standard work on the subject

This book is a remarkable achievement. Nikolaus Wachsmann has written the first integrated history of Nazi concentration camps, unifying in a single narrative the policies and measures governing the inception and growth of the system, the context in which the monstrous KL developed and how each of its stages and facets was recorded and remembered by its victims. The study is essential for a further understanding of the Third Reich

Nikolaus Wachsmann has written an admirable historical overview of the Nazi concentration camps, effectively combining decades of recent scholarship with his own original research. He captures both the trajectory of dynamic change through which the camp system evolved as well as the experiences and agency - however limited - of the prisoner community. This is an impressive and valuable book

Telling the story of the KL means facing up to a formidable challenge: how to make the camps relatable, as places where real people lived, worked and died, rather than transcendental symbols of evil? . . . [Wachsmann] proves himself equal to this challenge . . . thanks to Wachsmann's skill as a writer, it manages to be much more than a doleful trudge through a universe of ever-increasing death and terror

Monumentally impressive . . . seems certain to become the definitive history of the Nazi concentration camps . . . his scholarship brings new life to a familiar subject

Profoundly important . . . exceptional . . . will surely become the standard work on the subject

Wachsmann has in effect united the best of the German and the British schools of grand World War II history: hugely but humbly exhaustive research with attention to character and to detailed narrative

Wachsmann's meticulous research and unwavering eye for detail is never permitted to detract from the individual human tragedies . . . so much more than another academic record of the holocaust

Hugely impressive . . . Wachsmann has produced the standard historical work on the Nazi camps . . . KL represents the acme of what the historical disciple can achieve

[A] magnificent work of scholarship . . . every page of Nikolaus Wachsmann's magisterial account is suffused with humanity

Gripping, humane, and beautifully written

A work of prodigious scholarship

Every page is suffused with humanity and anyone who wants to understand the Nazis should read it

Hugely impressive . . . Wachsmann pulls off a remarkable feat: he not only provides an account of Konzentrationslager, or KL of the books title, he does so in a readable, accessible way. KL represents an acme of what the historical discipline can achieve

It is difficult to do justice to the brilliance of Wachsmann's comprehensive history . . . engrossing as well as illuminating

Wachsmann's book is a world-making history

In devastating and undeniable detail, KL sets out the full story of the camps

A staggeringly well-informed and enormously moving record of suffering and evil . . .the terrifying lesson of Wachsmann's account is not that any of us might have been an inmate. It is that any of us might have been a guard

A truly excellent book on one of history's darkest moments

This is both a panoptic and an intimate history of the camps: we get the big picture as well as the telling detail
(the SS officer who opened doors with his elbow rather than his hand because he was worried about germs). It is a huge and very necessary contribution to our understanding of this obscene subject. It makes us think anew: about how the camps worked, what it was like in them and how they fitted into the machinery of the state

Dr Nikolaus Wachsmann was born in Munich, Germany. He obtained a PhD in History from Birbeck College at the University of London and was a joint winner of the Fraenkel Prize in Contemporary History.
