Ptolemy Keraunos
Arsinoe II fled to Egypt to Ptolemy II for protection against Ptolemy Keraunos. Ptolemy Keraunos' brief reign ended in 279 BC as he was captured and killed during the Gallic invasion of the Balkans led by Bolgios who conducted a series of mass raids on mainland Greece. Ptolemy by then was the oldest and only surviving son of Lysimachus. As the son and heir of the great Lysimachus, he seemed to be destined to be something more than a mere regional dynast after the assassination of half-brother Agathocles. His new position as the heir apparent as one of the great empires of the early Hellenistic period didn't last long after the deaths of his father, Lysimachus, and uncle and stepfather, Ptolemy Keraunos, which lead to the complete dissolutions of their kingdoms.
