The pickelhaube was first introduced in the Prussian army in 1842, and it quickly became a symbol of the German military. It was worn by German troops in the Franco-Prussian War (1870-1871), the First World War (1914-1918), and the Second World War (1939-1945).
The pickelhaube was phased out of service in the German military after the First World War, but it continued to be used by some police and paramilitary units until the end of the Second World War. The pickelhaube is still a popular symbol of German militarism, and it is often seen in movies and television shows about World War I and World War II.
