When discussing the Middle Ages and military history one usually hears a large amount about the use of the longbow revolutionizing the way battles were fought. However, for many centuries prior to the longbow becoming a dominant force in European military history culminating in the 1415 Battle of Agincourt, the Trabuco can lay claim to being the most important piece of war machinery in the period; by the 12th-century, the Trabuco had moved from its origins as a human propelled catapult to a traction unit capable of throwing rocks and objects vast distances.
The roots of the growth of the Trabuco can be found in the development of the weapon by Chinese military leaders in the 4th-century B.C. with the catapult arm and sling powered by humans. As time moved on the Trabuco was taken around the world by merchants from the Middle East who took the technology to military leaders such as the legendary Muslim leader, Saladin; the same movement of merchants information and technology saw the Trabuco identified by the Byzantine Empire in the 6th-century as they battled Muslim forces sweeping into Europe through the gateway of Constantinople according to youtube.com.

Introducing the traction Trabuco had a major impact on the military use of some of the world’s leading generals in the Middle Ages who found they had the ability to move their forces to the relative safety of hundreds of meters from the enemy before using the Trabuco to create a barrage against enemy lines. Following the First Crusade of the 11th-century, the Trabuco became an important weapon for European forces who were forced to design their own versions of the weapon in an attempt to bring an end to the many siege actions taking place across the six crusades.
At various times of gunpowder shortages, the Trabuco has made a return to using including the 16th-century destruction of the Aztec Empire by Spanish forces and during the 2013 Syrian civil war.
