The first comprehensive presentation of foreign policy events in the entire ancient world. Ernst Baltrusch's book is the first monograph on ancient foreign policy from the beginnings of Greek and Roman antiquity (around 800 BC) to the onset of late antiquity (around AD 300). It addresses external relations in the Greco-Roman world in a broad sense. Thematic focuses include foreign political relations, the major alliance systems (Symmachy, Athenian maritime league, Peloponnesian League, the Roman confederation system), as well as the formations of empires under Alexander the Great and the Romans. The emphasis is on the institutions of ancient foreign policy and the forms of foreign political communication.
