Alexander (Ancient Greek: Ἀλέξανδρος) (died 247 BC) was a Macedonian governor and tyrant of Corinth.
[citation needed] At his father's death around 263, Alexander inherited his position, which went then far beyond that of a mere Macedonian garrison commander and resembled more a dynastic regency in Greece.
For some years, Alexander remained loyal to Antigonus, but by 253 he accepted subsidies from the Egyptian king Ptolemy II Philadelphus and resolved to challenge the Macedonian supremacy seeking independence as a tyrant.
In 249, Alexander carried victories over Athens and Argos and the following year he possibly forced his enemies to accept a truce.
[citation needed] Alexander's widow Nicaea assumed control of his possessions, but after the death of her protector Ptolemy Philadelphus in 246 her position was weakened.
