Antigonus Gonatas's victory over the Gauls at Lysimacheia left them as a master of Macedonia. In the later months of 275 Pyrrhus, the king of Epirus, returned home from the fiasco of his wars in Italy and Sicily, afterwards he invaded Macedonia. In 268, Macedonian progress in southern Greece was interrupted by the outbreak of a war directed against the Macedonian positions there and led by Athens and Sparta. The main evidence for its outbreak is an inscription containing an Athenian decree moved by Chremonides who was one of a group of anti-Macedonian statesmen active in Athens at this time. During the Chremonidean War the Aetolians, nominally neutral, had in fact favoured the allies. The Chremonidean War ended with a resounding victory for Macedonia. The failure of Athens and Sparta to co-ordinate their attack left Corinth firmly in his hands, or rather in those of his half-brother Craterus. In addition Athens and Attica were now also under Macedonian control.
