A
pike is a
pole weapon, a very long thrusting
spear formerly used extensively by
infantry. Unlike many similar weapons, the pike is not intended to be thrown. Pikes were used regularly in European warfare from the
early Middle Ages until around 1700, and wielded by foot soldiers deployed in close quarters. The pike found extensive use with
Landsknecht armies and
Swiss mercenaries, who employed it as their main weapon and used it in
pike square formations. A similar weapon, the
sarissa, was also used by
Alexander the Great's
Macedonian phalanx infantry to great effect. Generally, a spear becomes a pike when it is too long to be wielded with one hand in combat.
