She was the first daughter and second child born to the diadochus who was King of Thrace, Asia Minor and Macedonia, Lysimachus from his first wife the Queen consort, Nicaea of Macedon.
[8] At an unknown date, Lysimachus renamed the city Smyrna to Eurydiceia in honor of Eurydice, an innovation that did not last long.
Lysimachus gave Eurydice in marriage to her maternal cousin Antipater I,[11] the son of the rulers of Macedonia, Cassander and Thessalonike.
[13] In her life, Eurydice was a participant in the never ending conflict over control of Macedonia in the generations after the death of Alexander the Great.
When Demetrius I arrived with his troops he had Alexander V murdered and drove out Antipater and Eurydice out of Macedonia.
