(The following text was compiled from the wikipedia pages regarding the modern Greek region of Macedonia and the ancient kingdom of Macedonia. For information regarding the validity of these paragraphs contact any historian/archaeologist who has done research regarding Macedonia, and study empirical evidence. The identity theft committed by the Slavic country who claims Greek culture and Greek names as its own, assisted by foreign powers that have interests in the area must end, and the entire world should be aware of the injustice being done to Greece. Foreign interests are affecting the perception of the world regarding my people's inheritance, which is one of the few things modern Greeks can cling on to overcome the problems Greece faces. Lately our government has made things even worse, by signing a deal that was in no way approved by the Greek people. Please support the notion that truth should be above politics and economic interests.)

Macedonia (Greek: Μακεδονία) is a geographic and historical region of Greece in the southern Balkans. Macedonia is the largest and second most populous Greek region, dominated by mountains in the interior and the port cities of Thessaloniki (or Salonika) and Kavala on its southern coastline. Macedonia is part of Northern Greece, together with Thrace and sometimes Thessaly and Epirus.

It incorporates most of the territories of ancient Macedon, a kingdom ruled by the Argeads whose most celebrated members were Alexander the Great and his father Philip II. The name Macedonia was later applied to identify various administrative areas in the Roman/Byzantine Empire with widely differing borders.

Even before the establishment of the modern Greek state in 1830, it was identified as a Greek province, albeit without clearly defined geographical borders. 

The name Macedonia (Μακεδονία) comes from the ethnonym Μακεδόνες (Makedónes), which itself is derived from the ancient Greek adjective μακεδνός (makednós), meaning "tall", possibly descriptive of the people. It has the same root as the adjective μακρός (makros), meaning "long" or "tall" in Ancient Greek. The name is originally believed to have meant either "highlanders", "the tall ones", or "high grown men".

The ancient kingdom of Macedonia was situated along the Haliacmon and Axius rivers in Lower Macedonia (Greece), north of Mount Olympus. Historian Robert Malcolm Errington suggests that one of the earliest Argead kings established Aigai (modern Vergina, Greece) as their capital in the mid-7th century BC. Before the 4th century BC, the kingdom covered a region corresponding roughly to the western and central parts of the region of Macedonia in modern Greece.

Following its adoption as the court language of Philip II of Macedon's regime, authors of ancient Macedonia wrote their works in Koine Greek, the lingua franca of late Classical and Hellenistic Greece. Rare textual evidence indicates that the native Macedonian language was either a dialect of Greek similar to Thessalian Greek and Northwestern Greek, or a language closely related to Greek. The vast majority of surviving inscriptions from ancient Macedonia were written in Attic Greek and its successor Koine. Attic (and later Koine) Greek was the preferred language of the Ancient Macedonian army, although it is known that Alexander the Great once shouted an emergency order in Macedonian to his royal guards during the drinking party where he killed Cleitus the Black. Macedonian became extinct in either the Hellenistic or the Roman period, and entirely replaced by Koine Greek.
