Timeline

1. c. 1000–1050Northern Italy · ItalyMechanical knowledge from the Byzantine and Arab worlds entered Western Europe via Italian trade routes and warfare; the crossbow was first used in city-state conflicts for city defense and ambush, its manufacture depending on skilled bowyers and composite bow-limb materials.
2. 1051–1060Western Europe · Western EuropeCrossbows were mass-issued in France, the German states, and the armed cities of the Low Countries to supplement longbows and trebuchets; the Second Lateran Council's (1139) condemnation of the crossbow reflects the ethical and tactical challenge it posed to the knightly class.
3. 1100–1300Levant and Western European fortresses · LevantIn Crusader sieges and castle assaults, crossbows and windlass crossbows were used together to form an infantry ranged-fire layer; guilds in various countries regulated crossbow makers and standardized bow-limb tension, promoting weapon standardization and codified tactics.
