Aegae (Macedonia) in the context of "Pella"

Macedonia (/ˌmæsɪˈdoʊniə/ MASS-ih-DOH-nee-ə; Greek: Μακεδονία, Makedonía), also called Macedon (/ˈmæsɪdɒn/ MASS-ih-don), was an ancient kingdom on the periphery of Archaic and Classical Greece, which later became the dominant state of Hellenistic Greece. The kingdom was founded and initially ruled by the royal Argead dynasty, which was followed by the Antipatrid and Antigonid dynasties. Home to the ancient Macedonians, the earliest kingdom was centred on the northeastern part of the Greek peninsula, and bordered by Epirus to the southwest, Illyria to the northwest, Paeonia to the north, Thrace to the east and Thessaly to the south.

Before the 4th century BC, Macedonia was a small kingdom with its capital at Aigai, outside of the area dominated by the great city-states of Athens, Sparta and Thebes, and briefly subordinate to the Achaemenid Empire. During the reign of the Argead king Philip II (359–336 BC), Macedonia (with its capital at Pella) subdued mainland Greece and the Thracian Odrysian kingdom through conquest and diplomacy. With a reformed army containing phalanxes wielding the sarissa pike, Philip II defeated the old powers of Athens and Thebes in the Battle of Chaeronea in 338 BC. Philip II's son Alexander the Great, leading a federation of Greek states, accomplished his father's objective of commanding the whole of Greece when he destroyed Thebes after the city revolted. During Alexander's subsequent campaign of conquest, he overthrew the Achaemenid Empire and conquered territory that stretched as far as the Indus River. For a brief period, his Macedonian Empire was the most powerful in the world – the definitive Hellenistic state, inaugurating the transition to a new period of Ancient Greek civilization. Greek arts and literature flourished in the new conquered lands and advances in philosophy, engineering, and science spread across the empire and beyond. Of particular importance were the contributions of Aristotle, tutor to Alexander, whose writings became a keystone of Western philosophy.

The Balkan campaign of Alexander the Great took place in 335 BC, against a number of rebellious vassals of the Macedonian kingdom. Alexander successfully pacified each in turn, leaving him free to begin the long-planned invasion of Persia.

In 336 BC, while attending the wedding of his daughter by Olympias, Cleopatra and Olympias' brother, Alexander I of Epirus at Aegae, Philip II was assassinated by the captain of his bodyguard, Pausanias. Philip's son, and previously designated heir, Alexander was proclaimed king by the Macedonian noblemen and army.

Vergina (Greek: Βεργίνα, Vergína [verˈʝina]) is a small town in Northern Greece, part of the Veria municipality in Imathia, Central Macedonia. Vergina was established in 1922 in the aftermath of the population exchanges after the Treaty of Lausanne and was a separate municipality until 2011, when it was merged with Veroia under the Kallikratis Plan.

Vergina is best known as the site of ancient Aigai (Ancient Greek: Αἰγαί, Aigaí, Latinized: Aegae), the first capital of Macedon. In 336 BC Philip II was assassinated in Aigai's theatre and his son, Alexander the Great, was proclaimed king. While the resting place of Alexander the Great is unknown, researchers uncovered three tombs at Vergina in 1977 – referred to as tombs I, II and III.
