Did Alexander conquer the world?

 It's often said that Alexander the Great conquered the world. Alexander is a figure from the 4th century BCE. He was born in northern Macedonia, where city-states, including Athens, where the brilliant civilization of ancient Greece blossomed. After taking over the throne from his father Philip II in 336 BC, he began an expedition to the East in 334, destroying the Persian Empire, which had fought wars with Greece in the past, and conquering the Indus River. The story about him is that he cut the Gordian knot, which is a rich and unfastened knot, and 300 years later, Julius Caesar in Rome was amazed by the story and its brilliance. And not just conquering vast territories, but incorporating the highest order of Greek culture in the Middle East (Helenistic culture, Greece is sometimes called Hella) He's also the first person to advocate and practice globalization in this modern way. Moreover, it is said that when he started to conquer India, he cried because he was sad that there was no more land to conquer. But did Alexander really conquer the world? Let's first weigh the total area of the territory that he conquered. The land that he conquered today is as follows. Greece and parts of northern Greece, Turkey, Armenia, Syria, Lebanon, Israel, Jordan, Egypt, Iraq, Kuwait, Iran, Pakistan and Afghanistan, Turkmenistan, Greece to the west, the Indus River to the east, northern Egypt, and Turkmenistan to the north. So what is the total area mentioned above approximately? Roughly speaking, it's a little over five million square kilometers. By the way, the total land area of the world is just over 135 million square kilometers. So the area of land that Alexander conquers is about a quarter of the world's land, about 3.3 percent. If you exclude the New World, parts of Africa, the frozen land of Russia, Australia, etc., it's hard to exceed 10%. And most of the territory that he conquers is not much different from the Persian Empire that he conquers and by the time Alexander invades, the Persian Empire was already on the verge of disintegration, where its reputation as an empire was ending. So Alexander took over the empire with great ease, with little fighting other than the battle against Darius III's main forces. In fact, in terms of transportation and transportation at the time, we come to the conclusion that conquering the entire Persian Empire in just over a decade was a constant run and run without any particular obstacles. In conclusion, it's a great exaggeration to say that Alexander conquers the world and to put it exactly, he conquers the Middle East. Like Napoleon and Hitler had conquered Europe. I think it should be given to the Mongol Empire in the 13th century if it is given the honor of conquering the world. In terms of territory and population, the Mongols had never had an empire like that before or after that. (It was wider than the former Soviet Union.)
