Question

please help asap! please be very detailed and clear with the answer

Answer 1

Phillip of Macedonia and his famous son Alexander the Great in large part freed the city-state bonds of notable cities such as Athens and Sparta. For the first time, the city states stopped fighting each other and rallied around the conquerors Phillip and Alexander. I am sure that the unifying force of the two, Phillip and Alexander, brought relief and artistic and scientific growth to the city states of Greece and Macedonia, as their common enemy became someone way outside their domiciles, namely, Persia. A common enemy surely brought all the city states together, at least, on the surface. Alexander and his famous horse, Bucephalus, cut the Gordian Knot and brought together all of Greece and Macedonia under one common threat.
