The Romans actually withdrew from Greece after the end of the conflict, but the resulting power vacuum quickly drew in Antiochus and subsequently the Romans, who defeated (192–188 BC) the last Mediterranean power that might even vaguely threaten their predominance. Having provided Rome with valuable naval help in her first foray into Asia, the Rhodians were rewarded with territory and enhanced status by the Treaty of Apamea (188 BC). The Romans once again evacuated the east – the Senate preferred clients to provinces – but it was clear that Rome now ruled the world and Rhodian autonomy was ultimately dependent upon good relations with them.
