Trabuco: The Historical War Machine

One of the aims of history is to give us the background of our the world. It enables us to understand how the globe has revolutionized over the years. On this basis, there are various terms in history that entail how people were governed and how they were able to access the resources that they never had. Notably, there are various ways in which the ancient people interacted and invaded other territories. War was one of the ways to attack their neighbors and get the resources that they did not have. Due to lack of civilization in the ancient days, war and colonization of other people were a common thing.


There were various tools that were during the war that included spears, bows, daggers, and arrows. These were one of the most ancient fighting tools. Later the machine known as Trabuco was invented in China and was mainly used by the Europeans. The Trabuco used the mechanism of the conversion of the potential energy to kinetic energy. Notably, in education, today students are taught on how the people in the middle age applied mechanics during their time of wars. The Trabuco would then throw a fire ball or big stones to the enemy territories according to The fire balls were stones that were wrapped by dry leafs that were lit and would then move in a projectile manner either to break the walls of the enemies all to fight the enemy so that they can leave the territory.

The attackers would they be able to invade the territories and acquire the resources that were owned by the people who have been attacked. Later the Trabuco was then introduced in Europe before the new invention was made. The use of Trabuco ended when there was the invention of the gun powder. The invention of gun powder made the Trabuco less effective as guns were more efficient and effective to use. Unlike the Trabuco that required several people to operate it, the gun just required one person.

It can be noted on that the ancient Trabuco is still seen in many of the museums both in the European countries and also in China.
