The royal tombs at Vergina were identified as the ancient capital of Aigai in the 1930s. A royal tomb identified as possibly Philip II of Macedonia, Alexander the Great's father, was found in 1977 by Manolis Andronikos.
There were at least three decades between the royal tombs at Vergina being identified as the ancient capital of Aigai, and the discovery of the royal tomb by Manolis Andronikos
