May I ask if ancient Macedonia was once a region of ancient Greece

No! You can look it up on the encyclopedia, and the first map clearly shows that ancient Greece was in the south-central part of the Balkan Peninsula, while Macedonia was in the northeast of the Balkans.

In addition, there are many periods in the transmission of Greek civilization, just like the transmission of Chinese civilization has experienced what Xia, Shang, Zhou, Yuan, Ming and Qing dynasties, and the same Greece was later replaced by the ancient Roman Empire, the Ottoman periods, and the rise of Macedonia should be a matter of Alexander's Empire. It should be the zone of influence of ancient Greek civilization. But it is not a region of ancient Greece.

was a region that was a slave-holding state in the 5th and 2nd centuries BC. Macedonia is located in the northern part of the Balkan Peninsula, and the mountainous area in the territory is called Upper Macedonia, and the coastal Aegean Sea is called Lower Macedonia. The inhabitants were mainly Greeks (Dorians), Thracians and Illyrians.

In the middle of the 5th century BC, a slave-owning state headed by a king first appeared in Lower Macedonia.

Culturally belongs. Politically they did not belong, they were in an alliance, and in fact Macedonia occupied Greece after the union broke down.

Ancient Greece included the northeastern part of the Mediterranean, the southern part of the present-day Balkan Peninsula, the western coast of the Asia Minor Peninsula, and many small islands in the Aegean Sea.

Macedonia is located in the middle of the Balkan Peninsula and borders Greece to the south. The Macedonian Empire, which rose to prominence in the 4th century B.C., conquered Asia Minor, Persia, Egypt and other places, spreading Greek civilization to all parts of the Middle East.

The period from Alexander's death in 323 BC to the Roman conquest of Ptolemaic Egypt in 30 BC is known as the Hellenistic Age. After Alexander's death, the empire he built fell apart, and in the first half of the 3rd century BC a series of Hellenistic states were formed. The more important of these are the Ptolemaic dynasty centered on Egypt, the Seleucid kingdom centered on Syria, and the Macedonian kingdom centered on Macedonia.

In 277 BC, Antigonus-Gonnat founded the Antigonus dynasty, which was under the rule of Macedonia proper, as well as the Greek city-states. There have always been anti-Macedonian forces in southern Greece, in which the Aetolia League and the Acai League played an important role. By the time Rome expanded into the eastern Mediterranean, it had taken advantage of the contradictions between the city-states to turn them against each other and cause them to decline separately.

After Alexander's expedition, the phenomenon of land annexation within the Greek city-states became increasingly serious, and the social crisis caused by the disparity between the rich and the poor exacerbated the economic decline of the city-states. In the second half of the 3rd century BCE, the Spartan city-state attempted to carry out social reforms, but failed due to internal and external resistance. At the same time, the forces of the emerging Roman Republic invaded the Balkans, showing their unstoppable power.

In 168 BC, the Romans occupied Macedonia proper, and by 146 BC, all of Greece was under Roman rule. The Seleucid kingdom was gradually annexed by the Romans until 30 BC, when the last Hellenistic kingdom, the Ptolemaic dynasty, was wiped out by Rome, ending the history of ancient Greece.

Macedonian bar.

Macedonia is located in the northern part of Greece, on the edge of Greek civilization, and is considered a barbarian by the Greeks. But from the 4th century BC onwards, Macedonia gradually became an important state in northern Greece. In 395 BC, Philip II ascended the throne.

Under Philip, Macedonia became the premier military power in the Balkans. Faced with the rise of Macedonia, Greece established an anti-Macedonian alliance led by Athens. In 338 BCE, Macedonia defeated the Greek coalition at Chaeronea and gained control of all of Greece.

In 336 BC, Philip was assassinated, and his son Alexander ascended the throne. Alexander soon after his accession to the throne put down the uprisings of the Greek city-states and consolidated his power.

The history of Macedonian high school is told.

The history of the third year of junior high school is also taught.

It can't be said that Greece persecuted, because the citizens in it are not Macedonian descendants, so the name was changed.

Because Macedonia joined NATO, it was renamed North Macedonia.

The reason for this has to be answered from history:

Greece was the birthplace of European civilization in ancient times. However, it was conquered by the Macedonian kingdom in 330 BC, and from then on, the Greek regions were subject to foreign rule (e.g. the Roman Empire, the Ottoman Empire, etc.). Coupled with the fact that there are administrative districts with related names within the territory of Greece, the Macedonian state is a sensitive name for Greeks.

Avoid overlapping names in your own area.

This was not forced by Greece, but Macedonia itself wanted to change.

For ancient Macedonia, the Greek side believes that the ancient Macedonians are a branch of the ancient Greeks, and the ancient Macedonian kingdom belongs to Greek history. North Macedonia claimed to be the successor to the Kingdom of Macedonia and the Socialist Republic of Macedonia after its independence from the former Yugoslavia, and therefore insisted on using the name "Macedonia". It was not until June 2018 that the two prime ministers reached an agreement on a name change.

On November 20, 1991, Macedonia declared independence. He joined the United Nations in 1993 under the provisional name "The former Yugoslav Republic of Macedonia".

On February 11, 2019, the Macedonian Parliament passed a constitutional amendment to change the name of the country to "Republic of North Macedonia".

Judging from the current map of Greece and Macedonia, the two countries share a border, and the territorial definition is ambiguous compared to the map of ancient Greece. From the perspective of Greece today, if the name of Macedonia is recognized, it is easy to cause disputes over the definition of national borders, not to mention the dispute between Macedonia and Greece over whose ancestor Alexander is.

Macedonia is the former Yugoslav Republic that became independent in 1991 and joined the United Nations in 1993 as the "former Yugoslav Republic of Macedonia". Since then, Macedonia has insisted on using the constitutional name "Republic of Macedonia" internally and externally. However, the Greek side believes that Macedonia's constitutional name implies that it has territorial claims to the northern Greek province of Macedonia, requiring it to continue to use the term "former South Republic of Macedonia".

The Macedonians are actually an ethnic group in the Greek nation, similar to the Hakkas, Shanghainese, and Shandong people today, and they are a small ethnic group in a large nation. Most of the inhabitants of the Republic of Macedonia in the former Yugoslavia are not descendants of the historical Macedonians, but simply use historical names. However, there are real Macedonian descendants in Greece, and the Macedonians in Greece also have a tendency to secession.

If there is a Macedonian state in the world, it may cause the Macedonian separatists in Greece to merge with it, which is not conducive to the stability and unity of Greece. Therefore, Greece is persistently opposed to the use of the name of Macedonia in Macedonia.

For ancient Macedonia, the Greek side believes that the ancient Macedonians are a branch of the ancient Greeks, and the ancient Macedonian kingdom belongs to Greek history. The Republic of Macedonia, for its part, claimed to be the successor of the Kingdom of Macedonia and the Socialist Republic of Macedonia, and therefore insisted on using the name "Macedonia". Formerly Macedonia was part of ancient Greece, the main body of present-day Macedonia is the Slavs and part of the former Yugoslavia.

Greece then had a province of Macedonia, the same name as the Republic of Macedonia).
