This article explores what Cicero as a political thinker can offer to the study of international relations. Although previous readings of Cicero have emphasized his Stoic influences and his natural law teaching as the basis of a cosmopolitan world society, I emphasize the way in which Cicero can deepen the concept of international society. International society relies on certain norms and institutions to function properly, such as international law, sovereignty, and the use of war to restrain violence and redress injustice. We find all these concepts articulated clearly in Cicero’s moral and political thought. Cicero also shows the limits of these institutions and norms, explaining why none of them is absolute. Finally, Cicero adds to our theorizing about international society by drawing attention to the role of honor, ruling, and inequality in international society. As such, classical political thought, and Cicero’s in particular, provide a valuable resource for future thinking about international theory.
