The Portuguese people had been in existence since 1200 A.D. They first had a kingdom that lasted until the 1400s. They then had an empire that lasted until 1910 and finally terminated in 1999 when Macau was handed back over to China. During the era that Portugal was a kingdom and an empire they used the trabuco (or trebuchet) to stop conquer foreign lands.
The Portuguese people conquered started their kingdom by helping to drive out the Moors from their lands. At the time the land belonged to the African Moors and barbarians. Alfonso the I of Portugal conquered the area and officially put Portugal on the map. He used his armies to help drive out the Moors and other Muslim rulers in that area. During the fighting they used the trebuchet to win battles.
After Portugal became an official empire, its next step was to become an empire. The Prince Henry the Navigator was influential explorer who brought the world of exploration into being. It was through his conquests of foreign lands that the other European nations followed suit. Spain, England even France were all persuaded to conquer other lands based off Portugal’s conquest of Angola, Mozambique, and Guinea-Bissau in West Africa. They used the trebuchet to help in these conquests.
Remember that the Portuguese were trying to establish trade routes with various kingdoms and empires in the east. The Venetians were blocking them from carrying out this trade. So, they had to establish various bases along the coasts of Africa.
Not only did they establish trade cities along the coasts they also conquered lands in Asia and in South America. The trabuco was used to subject Brazil in the 1500s. They also protected Goa, India with the trabuco in some of the key trade cities that they established.
Throughout its long years as an empire the Portuguese used the trabuco to help in its conquests. While the Portuguese Empire is no longer around, their use of the trabuco is well remembered. This nation would not be where it is today because this weapon helped to forge the nation that is now Portugal.
