At the beginning of the 4th century BC, the capital of the Macedonian kingdom was transferred to Pella.
Under Philip II and Alexander III, Pella became a metropolis with an impressive complex of palaces and luxurious private houses.
The city was founded by Archelaus (413-399 BC) as the capital of his kingdom, replacing the older palace-city of Aigai (Vergina). After this, it was the seat of the king Philip II and of Alexander, his son.
