Ages, they soon came to be made entirely from forged steel in many societies after about 950 AD. At that time, they were purely military equipment, protecting the head from cutting blows with swords, flying arrows, and low-velocity musketry. Iron helmets were deployed into the cavalry of the Mali Empire to protect the cavalrymen and their mount. Military use of helmets declined after 1670, and rifled firearms ended their use by foot soldiers after 1700 but the Napoleonic era saw ornate cavalry helmets reintroduced for

Cushioning is used to negate concussive injuries. Researchers at the Lawrence Livermore National Laboratory published a study in 2011 that concluded that the addition of an ⅛ inch (3 mm) of cushion decreased the impact force to the skull by 24%.
