Weapon
Post-classical history

European warfare during post-classical history was dominated by elite groups of knights supported by massed infantry (both in combat and ranged roles). They were involved in mobile combat and sieges, which involved various siege weapons and tactics. Knights on horseback developed tactics for charging with lances, providing an impact on the enemy formations, and then drawing more practical weapons (such as swords) once they entered melee. By contrast, infantry, in the age before structured formations, relied on cheap, sturdy weapons such as spears and billhooks in close combat and bows from a distance. As armies became more professional, their equipment was standardized, and infantry transitioned to pikes. Pikes are normally seven to eight feet in length and used in conjunction with smaller sidearms (short swords).

In Eastern and Middle Eastern warfare, similar tactics were developed independent of European influences.

The introduction of gunpowder from Asia at the end of this period revolutionized warfare. Formations of musketeers, protected by pikemen, came to dominate open battles, and the cannon replaced the trebuchet as the dominant siege weapon.The Ottoman used the cannon to destroy much of the fortifications at Constantinople which would change warfare as gunpowder became more available and technology improved
