Editing Demetrius II Aetolicus (section)

==Biography==
Demetrius was born in either 275 or 274 BC and was the only child of King [[Antigonus II Gonatas]] by [[Phila (daughter of Seleucus)|Phila]], the daughter of [[Seleucus I Nicator|Seleucus I]].<ref>Carney, Elizabeth Donnelly (2000).

If this had occurred it would be in 256 or 257 BC.

On his accession, Demetrius faced a coalition of enemies which included the two great leagues. Usually rivals, the [[Aetolian League|Aetolian]] and [[Achaean League]]s now became allies against the Macedonian power. He succeeded in dealing this coalition severe blows, wresting [[Boeotia]] from their alliance. The revolution in [[Epirus (ancient state)|Epirus]], which substituted a republican league for the monarchy, gravely weakened his position.<ref name="EB1911"/>

During his reign, his kingdom extended<ref name="history_macedonia" />{{rp|321}} into [[Euboea]], [[Magnesia (regional unit)|Magnesia]], [[Thessaly]] and its environs, excluding [[Dolopia]] and possibly [[Skopelos (town)|Peparethos]] and [[Achaea Phthiotis]].

In 236 BC, he invaded [[Boeotia]], making the Boeotians submit<ref name="history_macedonia" />{{rp|326}} immediately.

In 234 BC, due to a federal republic<ref name="illyrians" /> replacing the monarchy in Epirus, which led to the events of 231 BC, Demetrius hired<ref name="cambridge" /> [[Agron of Illyria|Agron]] for military aid against the advancing [[Aetolians]]. His kingdom was not<ref name="history_macedonia" />{{rp|323}} threatened by the Illyrian [[Ardiaei]], ruled by Agron, despite them having gathered the greatest force in their history ({{Circa}} 231 BC), but Epirus needed some sort of force to deter them.

At some point in 230–229 BC in an unknown location in north-west Macedonia, the [[Kingdom of Dardania|Dardani]] defeated Demetrius who died shortly the next spring at the age of  {{Circa}} 45.<ref>{{Cite journal |last=Kuzmin |first=Yuri |year=2019 |title=KING DEMETRIUS II OF MACEDON: IN THE SHADOW OF FATHER AND SON |journal=Živa antika/Antiquité vivante |location=Skopje, North Macedonia |issue=69 |page=78}}</ref> His nine year old successor, the future Philip V, was deemed too young to rule by the Macedonian nobility and so Demetrius' half-cousin, [[Antigonus III Doson]], was made regent. The exact location of Demetrius' tomb remains unknown, but was likely in [[Beroea]] or [[Aegae (Macedonia)|Aegae]].
