The horrible life and work of Adolf Hitler have long raised puzzling questions for historians: How could the putatively civilized German nation allow a leader to plunge it into murderous barbarism? Why did the rest of Europe not put a stop to Hitler's rise before Germany could amass imperial power? How did Hitler transform bourgeois anti-Semitism into the Holocaust? John Lukacs addresses these and many other questions in this book of essays on the many problems Hitler and his regime present to historians. He assesses the contemporary, too-abundant literature, and makes some surprising and controversial evaluations.
