Deidamia I of Epirus

Deidameia (Greek Δηιδάμεια, † probably 298 BC) was a daughter of the king of Epirus Aiakides and a sister of King Pyrrhus of Epirus from the dynasty of Aiakiden.

Arranged by her aunt Deidameia Olympias was married as a child in the year 317 BC, King Alexander IV Aigos, the son of Alexander the Great. However, the marriage did not last long because in the spring of 316 BC Cassander, the Macedonian royal family, including Deidameia, besieged in Pydna and captured shortly thereafter. King Alexander IV Aigos remained until his assassination by 310 BC in the arrest, whether Deidameia was there at his side is unclear, at least she survived her husband.

During a Herafeier in Argos in 303 BC Deidameia was married to the ruler of Greece, Demetrios Poliorketes. As she came out of the sphere of Cassander is unclear, at least their marriage was based on a political motive. Her brother was Pyrrhus were displaced by Cassander from the domination of Epirus, which is why he is now the principle of " the enemy of my enemy is my friend " following an alliance with Demetrius Poliorketes sought, which in turn was the worst enemy Cassander in Europe. She was already the third official wife of polygamous living Demetrios. The marriage produced a son named Alexander was common († probably around 246/240 BC) produced.

After the defeat at the Battle of Ipsos 301 BC, the reign of Demetrius collapsed in Greece. Deidameia was at this time in Athens ( the Parthenon as a residence ), where supported by Demetrios Democrats were overthrown by an oligarchic counter-movement. The new rulers referred Deidameia the city, but they led her royal dignity according to Megara, which was still to Demetrios. From there they traveled around 299 BC to Cilicia, which Demetrios had retaken by Pleistarchus where she probably died shortly thereafter.
