Demetrias, Corinth and Chalcis on Euboea had great strategic value. Philip V aspired to peace cooperation with Greeks within the framework of the Common Peace treaty. For the transitional period the king tried to establish a new system of control over the Greek states. This system included three levels: (1) strong bases or «fetters of Greece» as Philip himself had once called them; (2) garrisons in large cities and (3) officers who were in charge of Macedonian affairs in certain areas. The most stable element of system – «fetters of Greece» – became a subject of anti-Macedonian propaganda. The Greeks regarded Philip as oppressor and tyrant, which resulted in a crash of his plans.
