Victory over Persia led to the rise of the Athenian Empire, conflict between Athens and Sparta and Sparta’s eventual victory in the Peloponnesian War. These years cover the transition from archaic to classical Greece, the Periclean age of Athens, the masterpieces of art, architecture and literature which are the supreme legacies of the Greek world, the contrasting lifestyles of Sparta and democratic Athens, and the careers of Alcibiades, Socrates and their famous contemporaries. They are studied the History of Thucydides, antiquity’s most masterly analysis of empire, inter-state relations and war, which Thucydides claimed to have written, justifiably, as ‘a possession for all times’. The issue of Thucydides’ own bias and viewpoint and his shaping of his History remain among the storm centres of the study of antiquity and are of far-reaching significance for our understanding of the moral, intellectual and political changes in the Greek world. The period is also studied through inscriptions, whose context and content are a fascinating challenge to modern historians.
