Crossbow
The mechanized ranged weapon of the medieval era
The crossbow is a ranged weapon combining a horizontal bow with a mechanical trigger mechanism. Unlike a bow, it can deliver high power without extensive training, earning it the nickname "democratized weapon." Widely used in medieval European infantry and castle defense, it was famously banned by Pope Innocent II at the Second Lateran Council in 1139 (against Christians). Steel limbs replaced wood/horn composites in the 14th century, dramatically increasing penetration. Bolts are shorter and heavier than arrows, delivering powerful close-range penetration.
Origin
First developed in China's Warring States period (5th century BC) as the "nu" (弩), reaching Europe around the 10th century. Pope Innocent II banned its use between Christians at the Second Lateran Council in 1139, though the ban was largely ignored.
Features
- Horizontal bow + mechanical trigger design
- High power with minimal training
- Steel limbs for superior penetration
- Short, heavy bolts for armor penetration
- Windlass or stirrup cocking mechanisms

Usage
