However, in 229 BC, the Cleomenean War (229–222 BC) broke out between the Achaian League and Cleomenes III of Sparta. As a result, in 226 BC, Aratos of Sicyon the leader of the Achaian League forged an alliance with the Macedonian king Antigonus III. Ptolemy III responded by immediately breaking off relations with the Achaian League and redirecting his financial support to Sparta. Most of the rest of the Greek states were brought under the Macedonian umbrella in 224 BC when Antigonus established the "Hellenic League". However Aetolia and Athens remained hostile to Macedon and redoubled their allegiance to Ptolemy III. In Athens, in 224 BC, extensive honours were granted to Ptolemy III to entrench their alliance with him, including the creation of a new tribe named Ptolemais in his honour and a new deme named Berenicidae in honour of Queen Berenice II. The Athenians instituted a state religious cult in which Ptolemy III and Berenice II were worshipped as gods, including a festival, the Ptolemaia. The centre of the cult was the Ptolemaion, which also served as the gymnasium where the Athenian youth were educated.
