World War II: Heinrich Himmler orders a crackdown on the Edelweiss Pirates, a loosely organized youth culture in Nazi Germany that had assisted army deserters and others to hide from the Third Reich.

World War II or the Second World War was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks and aircraft played major roles, enabling the strategic bombing of cities and delivery of the first and only nuclear weapons ever used in war. World War II is the deadliest conflict in history, causing the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

The Edelweiss Pirates were a loosely organized group of youths opposed to the status quo of Nazi Germany. They emerged in western Germany out of the German Youth Movement of the late 1930s in response to the strict regimentation of the Hitler Youth. Similar in many ways to the Leipzig Meuten, they consisted of young people, mainly between the ages of 14 and 17, who had evaded the Hitler Youth by leaving school and were also young enough to avoid military conscription, which was only compulsory from the age of 17. The roots and background of the Edelweiss Pirates movement were detailed in the 2004 film Edelweiss Pirates, directed by Niko von Glasow.
