So I have significant conflicts or events that happened to the Greek world on this timeline, especially in the fifth and fourth centuries BCE. In the beginning of the fifth century BCE, you have the Greco-Persian Wars, where the Greek city-states are able to fend off attack from the great Persian Empire, and then they go on the offensive. But as we exit the fifth century BCE, the city-states start fighting amongst themselves. You have Athens leading the Delian League in a fight against Sparta and their allies, which significantly weakens the city-states. It ends with Athens losing, but all of the city-states have been weakened, and it leaves them open to be conquered by the Macedonians, in particular Philip of Macedonia, and then his son Alexander the Great is able to not just keep control of Greece, of the city-states, but conquer Egypt and Persia and get all the way to modern-day Afghanistan and Pakistan. But after his death, you then have his successors, and Greece falls under the Antigonid dynasty. But eventually, as we get into the second and first century BCEs, it goes under Roman control.
