Northwest Greek in the context of "Pella curse tablet"

The Macedonians (Ancient Greek: Μακεδόνες, Makedónes) were an ancient tribe that lived on the alluvial plain around the rivers Haliacmon and lower Axios in the northeastern part of mainland Greece. Essentially an ancient Greek people, they gradually expanded from their homeland along the Haliacmon valley on the northern edge of the Greek world, absorbing or driving out neighbouring non-Greek tribes, primarily Thracian and Illyrian. They spoke Ancient Macedonian, which is usually classified by scholars as a dialect of Northwest Doric Greek, and occasionally as a distinct sister language of Greek or an Aeolic Greek dialect. However, the prestige language of Macedon during the Classical era was Attic Greek, replaced by Koine Greek during the Hellenistic era. Their religious beliefs mirrored those of other Greeks, following the main deities of the Greek pantheon, although the Macedonians continued Archaic burial practices that had ceased in other parts of Greece after the 6th century BC. Aside from the monarchy, the core of Macedonian society was its nobility. Similar to the aristocracy of neighboring Thessaly, their wealth was largely built on herding horses and cattle.

Although composed of various clans, the kingdom of Macedonia, established around the 7th century BC, is mostly associated with the Argead dynasty and the tribe named after it. The dynasty, also known as the Temenid dynasty, was allegedly founded by Perdiccas I, descendant of the legendary Temenus of Argos, while the region of Macedon derived its name from Makedon, a figure of Greek mythology. Traditionally ruled by independent families, the Macedonians seem to have accepted Argead rule by the time of Alexander I (r. 498 – 454 BC). Under Philip II (r. 359 – 336 BC), the Macedonians are credited with numerous military innovations, which enlarged their territory and increased their control over other areas extending into Thrace. This consolidation of territory allowed for the exploits of Alexander the Great (r. 336 – 323 BC), the conquest of the Achaemenid Empire, the establishment of the diadochi successor states, and the inauguration of the Hellenistic period in West Asia, Greece, and the broader Mediterranean world. The Macedonians were eventually conquered by the Roman Republic, which dismantled the Macedonian monarchy at the end of the Third Macedonian War (171–168 BC) and established the Roman province of Macedonia after the Fourth Macedonian War (150–148 BC).

Ancient Macedonian was the language or dialect spoken by the ancient Macedonians during the 1st millennium BC. It was either an ancient Greek dialect—part of Northwest Greek or Aeolic Greek—or a distinct Indo-European language, related to Greek and part of the Hellenic branch. Spoken originally in the kingdom of Macedon, it gradually fell out of use during the 4th century BC, marginalized by the use of Attic Greek by the Macedonian aristocracy, the Ancient Greek dialect that became the basis of Koine Greek, the lingua franca of the Hellenistic period. It became extinct during either the Hellenistic or Roman imperial period, and was entirely replaced by Koine Greek.

While the bulk of surviving public and private inscriptions found in ancient Macedonia were written in Attic Greek (and later in Koine Greek), fragmentary documentation of a vernacular local Macedonian variety comes from onomastic evidence, ancient glossaries, and recent epigraphic discoveries in the Greek region of Macedonia, such as the curse tablets from Pella and Pydna.

The Proto-Greek language, also known as Proto-Hellenic, is the Indo-European language which was the last common ancestor of all varieties of Greek, including Mycenaean Greek, the subsequent ancient Greek dialects (i.e., Attic, Ionic, Aeolic, Doric proper, Arcadocypriot, Northwest Greek, ancient Macedonian—either a dialect or a closely related Hellenic language) and, ultimately, Koine, Byzantine and Modern Greek (along with its variants). Proto-Greek speakers entered Greece sometime between 2200 and 1900 BC, with the diversification into a southern and a northern group beginning by approximately 1700 BC.
