The Protected States
Far more insupportable was the condition--intermediate between formal sovereignty and actual subjection--of the African, Greek, and Asiatic states which were brought within the sphere of Roman hegemony through the wars of Rome with Carthage, Macedonia, and Syria, and their consequences. An independent state does not pay too dear a price for its independence in accepting the sufferings of war when it cannot avoid them; a state which has lost its independence may find at least some compensation in the fact that its protector procures for it peace with its neighbours. But these client states of Rome had neither independence nor peace.
In Africa there practically subsisted a perpetual border-war between Carthage and Numidia. In Egypt Roman arbitration had settled the dispute as to the succession between the two brothers Ptolemy Philometor and Ptolemy the Fat; nevertheless the new rulers of Egypt and Cyrene waged war for the possession of Cyprus. In Asia not only were most of the kingdoms--Bithynia, Cappadocia, Syria--likewise torn by internal quarrels as to the succession and by the interventions of neighbouring states to which these quarrels gave rise, but various and severe wars were carried on between the Attalids and the Galatians, between the Attalids and the kings of Bithynia, and even between Rhodes and Crete.
