Pickelhaube
The pickelhaube (German Pickel, "point" + Haube, "helmet") is a spiked helmet worn in the 19th century by German military forces.
The pickelhaube was originally designed in 1842 by King Frederick-Willliam IV of Prussia. and its use slowly spread to other German principalities.
In 1887, the Kingdom of Bavaria was the last German state to adopt the pickelhaube.
During World War I it was found that the helmet offered little protection to troops in the trenches. In 1916 it began to be replaced by the stahlhelm or "coal scuttle" helmet that would still be worn by German troops in World War II. The pickelhaube was reduced to ceremonial wear. With the collapse of the German Empire in 1918, the pickelhaube was completely abandoned.
