When were the Macedonians considered solely Greeks?

Hellenistic period.

The ethnic identity of the ancient Greeks was mainly based on blood and culture. However, during the Hellenistic period, cultural identity was more important. We can observe from many Eastern Hellenistic cities that some Eastern cities were not originally Greek immigrants. Established, but after receiving Hellenistic civilization, they would be regarded as Greeks and participate in Greek rituals, such as Sidon and Tire. The Macedonians were not considered Greeks before the fourth century BC. One of the reasons is that culturally they did not live in cities like the southern Greeks. Most of them lived in rural tribes with a semi-grazing economy. The attitude is also different from that of the Greeks, and overall they lack civilization.

With the urbanization and Hellenization of Philip and Arti, the Macedonians gradually became culturally the same as the Greeks, and more and more Greeks began to identify the Macedonians as Greeks. Even civilian Macedonians could participate in the Olympic Games, something that only the royal family could participate in before the Emperor. The Greek historian Polybius in the second century BC was biased against Macedonia in his works, but he still regarded the Macedonians as one of the Greeks. Although Strabo did not mention them in some chapters of his works, The inclusion of the Macedonians among the Greeks may, however, be due to the influence of citations from other early Greek works when writing, as we can see that Strabo includes the Macedonians among the Greeks in other passages.
