Almost immediately following the defeat of Macedon, Rome became embroiled in a war with the Seleucid Empire. This war too was decided mainly on land, although the combined Roman–Rhodian navy also achieved victories over the Seleucids at Myonessus and Eurymedon. These victories, which were invariably concluded with the imposition of peace treaties that prohibited the maintenance of anything but token naval forces, spelled the disappearance of the Hellenistic royal navies, leaving Rome and her allies unchallenged at sea. Coupled with the final destruction of Carthage, and the end of Macedon's independence, by the latter half of the 2nd century BC, Roman control over all of what was later to be dubbed "mare nostrum" ("our sea") had been established. Subsequently, the Roman navy was drastically reduced, depending on its Socii navales.
