Often stereotypically associated with the Prussian Army was the "Pickelhaube", or spiked helmet, in use in the 19th and early 20th centuries. Victorious battles were celebrated through military marches, such as the "Hohenfriedberger Marsch", allegedly written by Frederick the Great after Hohenfriedberg, and the "Königgrätzer Marsch", by the march composer Piefke. The Prussian "Großer Zapfenstreich" military tattoo is still in use by the modern "Bundeswehr". The Iron Cross was adopted by the German Empire and its successor states, and is also still used as a symbol of the "Bundeswehr".
