The German War: A Nation Under Arms, 1939-1945 is a non-fiction book written by historian Nicholas Stargardt. Centering upon the "thoughts and actions" of the citizens living inside Nazi Germany during the Second World War, the author argues that the war crimes committed by Adolf Hitler's totalitarian state had widespread awareness among regular people. Despite massive hardship, those citizens continued to fight in support of fascist ideology even when their cause appeared truly lost. Much of the moral callousness arose due to the fallout from the First World War, which impacted regular Germans' lives deeply, yet the far-right dictatorship had fundamentally managed a successful propaganda machine that brought mass public opinion onto the side of the regime.

Bloodlands: Europe Between Hitler and Stalin is a 2010 book by Yale historian Timothy Snyder. It is about mass murders committed before and during World War II in territories controlled by Nazi Germany and the Soviet Union.
