The Spangenhelm, or segmented helmet, was a popular medieval European combat helmet design of Late Antiquity and the Early Middle Ages. They are often contrasted with Eastern lamellar helmets.

The lamellar helmet was a type of helmet used in Europe during the Early Middle Ages. Examples are characterized by caps made from overlapping lamellar scales, in addition to a brow plate, cheek guards, and camail. They are distinct from the contemporary spangenhelm and crested helmets also found in Europe; unlike those, which are influenced by Roman designs, Lamellenhelme display eastern influence and have primarily been found in southeastern Europe. They are mostly associated with the Avars of Pannonia and the Lombards of Italy.
