Strengthening of Macedonia happened during the reign of the king?

It happened during the years of King Philip 2 of Macedon. This happened in the 4th century BC. Then the Macedonian kingdom rapidly began to gain power. At the same time, the Greek city-states were weakened and fragmented. This was taken advantage of by the Macedonian king, who, with the help of political intrigue and military force, was ultimately able to conquer a significant part of Greece. So after the battle in 338 BC, almost all Greek poleis (except Sparta) recognized the power of Macedonia.
