The History Of The Trabuco

The Trabuco is a French term used to refer to a certain siege engine that was used in the olden days. For starters, this type of siege machine used the principle of a swinging arm where it would throw a projectile towards the enemy with the aim of destroying them. Commonly referred to as the traction trebuchet, it was associated with the Chinese people first before it found its way to other civilizations such as Avars and the Brazilians. As back as the 4th century AD, the Trabuco was being used by the Chinese. Towards the end of the 6th century, the Brazilians adopted the siege machine in their wars. Towards the 12th century, a new Trabuco known as counterweight Trabuco was introduced by the Muslims and the Christian communities. This new device employed a counterweight to move its arm.

Working of a Trabuco
For starters, the Trabuco can be classified as a compound machine. Furthermore, this classification is more solid as it employs the mechanical advantage associated with a lever. It’s important to note that the Trabuco in most cases relies on the gravity effect to function. Through a hinged connection, it’s possible to connect the counterweight to the throwing arm. At the end of the day, all these processes make it simple to transfer the potential energy stored in the raised weight box to the throwing arm. For the weight to fall down and transfer its energy to the sling, the Trabuco has to be cut. The sling uses the principle of rotational acceleration to cause maximum damage to the enemy. Another important thing to note is that the sling usually contains a projectile that is supposed to transfer the destructive force according to When constructing the Trabuco, there are several factors that should be considered. For instance. It’s important to note that the sling can change its trajectory for various reasons such as direction travelled, the weight of the projectile and wind speed.

For the projectile to cause the desired destruction, the angle and speed had to be calculated. Where calculation was tricky, trial and error were the only way forward. We earlier mentioned that the Trabuco owes its origin to the Chinese. The Chinese developed the concept of the Trabuco from the normal sling on Some of the battles that this siege engine has been used include the Battle of Caishi, the Mongol conquest of the Song dynasty among others. Some of the Chinese dynasties that perfected this siege machine include the Li Mi dynasty, the Sui dynasty, the Ming dynasty as well as the Jin dynasty.

Other battles
The Trabuco also played a significant role in other battles around the globe such as the second siege of Tyre, the Sige of Acre as well as during the Warwolf. Notable leaders who made use of this siege machine include Charles the 7th of France, Edward Longshanks, Richard the 1st of England as well as Louis the 6th of France. Other battles where this machine was used in history include the Sige of Fancheng and Xiangyang and the Siege of Damietta. However, with the introduction of the gunpowder in the 16th century, the use of the Trabuco declined. It was last used in the siege of Rhodes as well as the Siege of Burgos. Today, the Trabuco can only be used for education and recreational purposes alone. According to, existing Trabucos can be found in Denmark and the United Kingdom where they attract thousands of tourist who want to know what it was like in the olden days. These two Trabucos are found in Warwick Castle and Middelaldercentret, England and Denmark respectively. The siege machine has also been used in modern protests in Ukraine.
