The correct name is National Liberation Front of South Vietnam, also known as Viet Cong.
This massive political organization counted with its own army, the People's Liberation Armed Forces of South Vietnam (PLAF). They fought against the US and forces from South Vietnam during the Vietnam War, with the aim of releasing the Southern half of the country from imperialism and capitalism. Eventually, they ended up becoming the war winners.
According to the writings of Vitruvius, the Greek mathematician Archimedes created a primitive elevator in 236 B.C. that was operated by hoisting ropes wound around a drum and rotated by manpower applied to a capstan. In ancient Rome, a subterranean complex of rooms, animal pens and tunnels stood beneath the Colosseum. At various intervals, elevators powered by hundreds of men using winches and counterweights brought gladiators and large animals up through vertical shafts into the arena for battle.
In 1743, Louis XV had what was referred to as a “flying chair” built to allow one of his mistresses to access her quarters on the third floor of the Palace of Versailles. Similarly, a “flying table” in his retreat château de Choisy allowed the king and his private guests to dine without intrusion from the servants. At the sound of a bell, a table would rise from the kitchen below into the dining room with an elaborate meal, including all of the necessary accoutrements.
By the mid-19th century, elevators powered by steam or water were available for sale, but the ropes they relied upon could be worn out or destroyed and were not, therefore, generally trusted for passenger travel. However, in 1852, Elisha Graves Otis invented a safety break that revolutionized the vertical transport industry. In the event that an elevator’s hoisting rope broke, a spring would operate pawls on the car, forcing them into position with racks at the sides of the shaft and suspending the car in place. Installed in a five-story department store in New York City in 1857, Otis’ first commercial passenger elevator soon changed the world’s skyline, making skyscrapers a practical reality and turning the most valuable real estate on its head—from the first floor to the penthouse.
Byzantine Empire
Explanation:
- The Eastern Roman Empire (or Byzantine Empire) was the only country on this side of the Chinese Wall that lasted from late antiquity to the end of the Middle Ages.
- It went through the ups and downs and was one of the most significant civilizations in human history. It exerted a great cultural influence on a whole range of medieval states and peoples.
- Unlike the Western Roman Empire, which was overthrown by barbarians in 476 AD, the Eastern Roman Empire continued to live for another thousand years.
- Thanks to the denser population, larger cities, and a stronger economy, it has more easily withstood the economic crisis of the 3rd century, one of the greatest crises known in world history.
- Byzantine Empire rested on three foundations, namely: Roman state system, Greek culture and Christianity. Without any of these three elements it cannot be imagined, and it is only through their permeation that a Byzantine civilization is created. Byzantium, which for centuries was the guardian and restorer of ancient heritage, has no historical successor.
