In this book Dr Low explores the assumptions and principles which determined the conduct and representation of interstate politics in Greece during the fifth and fourth centuries BC. She employs a wide range of ancient evidence, both epigraphic and literary, as well as some contemporary theoretical approaches from the field of International Relations. Taking a thematic rather than a chronological approach, she addresses topics such as the nature of interstate society in the Greek world; the sources, scope and enforcement of 'international law'; the nature of interstate ethics and morality; interventionism and imperialism; and the question of change and stability. She argues that classical Greece's reputation for unrestrained and unsophisticated diplomacy is undeserved, and shows that relations between Greek city-states were shaped by and judged according to a complex network of customs, beliefs and expectations which pervaded all areas of interstate behaviour.
