A drawing of an archer firing a crossbow

The crossbow, or arbalest, is a bow which consists of a bow-like arc called prod and cross-wise body called stock and trigger mechanism. The crossbow is an invention in which the stock, a piece of wood is mounted on two other crossing pieces. Crossbows shoot short arrows called bolts which are similar to arrows. The crossbow was first created by the Chinese people in circa 6 B.C. The crossbow was introduced to China during the Warring States period. This period lasted over three centuries where neighbouring Chinese states fought mercilessly for dominance and territory. Throughout this span of time the crossbow evolved which made it easier to carry and improved firing accuracy. This highly sought after weapon led to the success of the Han and Song empires.
