The halberd is a two handed pole weapon. Introduced in the 14th and 15th centuries. It consisted of an axe blade topped with a spike mounted on a long shaft of wood. It was normally used by mounted combatants but also used by foot soldiers.
The halberd was mostly used by the early Swiss armies. It is still commonly used by the Swiss Guard in the Vatican.
It was said to be the single stroke of a halberd-wielding peasant that killed the Duke of Burgundy.
It was normally 5 to 6 feet long.
