Alexander V of Macedon

Alexander V of Macedon (Greek: Ἀλέξανδρος Εʹ ὁ Μακεδών; died late 294 BC) was the second son of Cassander and Thessalonike of Macedon, who was a half-sister of Alexander the Great.

When Antipater murdered their mother and ousted him from power, Alexander turned to Pyrrhus and Demetrius I for help in recovering his throne.

To the former he promised, as the price of his alliance, the land on the sea-coast of Macedonia, together with the provinces of Ambracia, Acarnania, and Amfilochia.

[2] Demetrius, according to Plutarch, arrived after Pyrrhus had retired, and when matters had been settled between Alexander and Antipater.

Here, at Larissa, Alexander went to dine with Demetrius, and, taking no guards with him, was assassinated, together with his friends who attended him.
