Arsinoe II married Lysimachus at the age of 15. After Lysimachus' death in battle in 281 BC, she fled to Cassandreia and married her paternal half-brother Ptolemy Keraunos. As he became more powerful, she conspired against him leading to the killing of her sons, Lysimachus and Philip. After their deaths, she fled to Alexandria, Egypt to seek protection from her brother, Ptolemy II Philadelphus; whom she later married. As a result, both were given the epithet "Philadelphoi" ("Sibling-loving (plural)") by the presumably scandalized Greeks.

Arsinoe II Philadelphos, died 270-268 BC.
