The Pickelhaube (pl. Pickelhauben; from German: Pickel, lit. 'point' or 'pickaxe', and Haube, lit. 'bonnet', a general word for "headgear"), also Pickelhelm, is a spiked helmet that was worn in the 19th and 20th centuries by Prussian and German military officers, firefighters and police. Although it is typically associated with the Prussian Army, which adopted it in 1842–43, the helmet was widely imitated by other armies during that period. It is still worn today as part of ceremonial wear in the militaries of certain countries, such as Sweden, Chile, andColombia.
