What made king philips army more powerful than those of the greeks city states

Greece was easily conquered by Macedonia because the city-states had grown weak and were unable to cooperate with each other in time to make a formidable opponent to the invaders.

Explanation:

After defeating the Greek city-states of Athens and Thebes at the Battle of Chaeronea in 338 BC, Philip II led the effort to establish a federation of Greek states known as the League of Corinth, with him as the elected hegemon and commander-in-chief of Greece for a planned invasion of the Achaemenid Empire of Persia.

Philip II was interested in conquering the Greek city-states south of Macedonia because he wanted to conquer the Persian Empire, but in order to conquer such a large empire he needed the help of the Greek city-states.
