Trebuchet

A trebuchet^{[nb 1]} (French: trébuchet) is a type of catapult^[5] that uses a rotating arm with a sling attached to the tip to launch a projectile. It was a common powerful siege engine until the advent of gunpowder. The design of a trebuchet allows it to launch projectiles of greater weights and further distances than that of a traditional catapult.

There are two main types of trebuchet. The first is the traction trebuchet, or mangonel, which uses manpower to swing the arm. It first appeared in China by the 4th century BC. It spread westward, possibly by the Avars, and was adopted by the Byzantines, Persians, Arabs, and other neighboring peoples by the sixth to seventh centuries AD.^[6]^[7]^[8]

The later, and often larger and more powerful, counterweight trebuchet, also known as the counterpoise trebuchet, uses a counterweight to swing the arm. It appeared in both Christian and Muslim lands around the Mediterranean in the 12th century, and was carried back to China by the Mongols in the 13th century.^[9]

Al-Tarsusi’s description and accompanying illustration are far from conclusive proof that this type of engine was developed in the Islamic world. At the siege of Acre in 1189-91, eyewitness sources provide no indication that the artillery employed by either the Muslim garrison or the crusaders was superior."
