Infantry Regiment 9 Potsdam

Infantry Regiment 9 of Potsdam (I.R. 9) was an infantry regiment in Weimar Republic's Reichswehr and Nazi Germany's Wehrmacht, descended from famed 1st Prussian Regiment of Foot Guards in the German Empire's Deutsches Reichsheer. Garrisoned at the cradle of Prussian army and rich with tradition, it was nicknamed 'Count Nine' (Graf Neun) or 'I.R. von 9' by its detractors because of high percentage of Prussian aristocrats and purported arrogance in its ranks.

Today it is most remembered for the fact that nineteen of its officers (or former officers) were involved in conspiracy against Hitler, more by far than any other German regiment. Most of them were executed or committed suicide after the failure of the 20 July plot to assassinate Hitler. Major General Henning von Tresckow and Lieutenant Colonel Fritz-Dietlof von der Schulenburg in particular were central figures in German resistance.

The regiment's tradition is continued by the Wachbataillon of the Bundeswehr.
