Fun fact:

Kaiser Wilhelm II himself is responsible for the "Hun" business. As he exhorted his troops in 1900 as they departed for China,

"When you meet the enemy,... you will give no pardon and take no prisoners. ...As the Huns a thousand years ago under King Etzel [i.e., Attila] made a name for themselves that has lasted mightily in memory, so may the name 'Germany' be known in China so that no Chinese will ever again even dare to look askance at a German."

From Isabel V. Hull's "Absolute Destruction: Military Culture and the Practices of War in Imperial Germany" (Cornell University Press, 2005).

Attila the Hun: role model.
