Alexander the Great of Macedonia was the son of King Philip of Macedonia, a small country in northern Greece. King Philip wanted Alexander to have the best education possible, so he made sure he received training from the greatest minds of the age, which included Aristotle. By the age of 18, Alexander became the general of the Macedonian army, and at the age of 20, his father was killed and he became king. It was the deepest desire of both he and his father to defeat the Persian Empire, and after his father's death, Alexander set out to do just that. The Macedonian army was a fraction of the size of the Persian army, however, within six years, he had conquered the entire Persian Empire, spreading Greek culture and civilization across the land, far faster than anyone would have imagined possible. Some areas he had to fight. He even went so far as to build a bridge, over the course of many months, to the island of Tyre, in order to conquer it. That bridge is still in existence today. Other areas welcomed him with open arms because they were tired of being under Persian rule. Egypt was one of these. In fact, because the Egyptians worshiped their pharaohs as gods, they welcomed Alexander and treated him as a god as well. When he had conquered as much as he was able, he turned around and headed back to Babylon to reign. At the age of 32, he was married to a Persian woman who was pregnant with his child, when he became gravely ill and died. Since the child was not yet born, his kingdom was divided between his four strongest generals: Lysimachus took Thrace and much of Asia Minor; Cassander took Macedonia and Greece; Ptolemy seized Egypt, Palestine, Cilicia, Petra, and Cyprus; while Seleucus took control of the rest of Asia. They were never able to unite the land under one ruler from that period forward.
The four wings on the leopard in Daniel 7:6 represent the extreme speed of conquest. Remember, the lion of Babylon had two wings. This also represented speed of conquest, so four wings means even faster, and Alexander did conquer Persia extremely quickly. The head of a beast often represents a ruler, and in this case, the leopard had four heads which were given authority to rule, and this represents the four generals who took control at Alexander's death. In Revelation 13:2, it makes reference to the beast resembling a leopard. This ties these two prophecies together. The seven-headed beast is not a big scary monster. It is simply representative of a timeline of events and bringing more information to light about what is to come.

Daniel 7:6
6 “After that, I looked, and there before me was another beast, one that looked like a leopard. And on its back it had four wings like those of a bird. This beast had four heads, and it was given authority to rule.
Revelation 13:2
2 The beast I saw resembled a leopard, but had feet like those of a bear and a mouth like that of a lion. The dragon gave the beast his power and his throne and great authority.
Daniel 8:5-8
5 As I was thinking about this, suddenly a goat with a prominent horn between its eyes came from the west, crossing the whole earth without touching the ground. 6 It came toward the two-horned ram I had seen standing beside the canal and charged at it in great rage. 7 I saw it attack the ram furiously, striking the ram and shattering its two horns. The ram was powerless to stand against it; the goat knocked it to the ground and trampled on it, and none could rescue the ram from its power. 8 The goat became very great, but at the height of its power the large horn was broken off, and in its place four prominent horns grew up toward the four winds of heaven.
Daniel 8:21-22
21 The shaggy goat is the king of Greece, and the large horn between its eyes is the first king. 22 The four horns that replaced the one that was broken off represent four kingdoms that will emerge from his nation but will not have the same power.
Daniel 2:32
32 The head of the statue was made of pure gold, its chest and arms of silver, its belly and thighs of bronze,
