In this lecture, Professor Kagan tells the story of the rise of Philip and describes his early actions: unifying Macedon, defeating barbarian armies, and creating a new, professional, national army. According to Professor Kagan, through these actions, Philip was able to make inroads into the Greek world. What made these inroads more effective was Philip's uncanny talent for diplomacy and the fighting between the various poleis. Eventually, the Greeks under the efforts of Athens and Demosthenes decided to face Philip in the battle of Chaeronea.

In this lecture, Professor Kagan describes the growth of a new power: Thebes. Under the leadership of Epaminondas and Pelopidas, Thebes grows into a major power among the Greek cities. In fact, the Thebans even rout the Spartans in a standard hoplite battle in the battle of Leuctra. Finally, Professor Kagan points out that by the time of Theban hegemony, the Greek world had experienced so many wars and conflicts that it opened the door to a powerful leader: Philip of Macedon.

In this lecture, Professor Kagan examines the continuation of Spartan tyranny over the Greek poleis and the response of the Greek world. According to Professor Kagan, it became clear that the Greek poleis needed to do something to check the power of Sparta. So, Thebes, Argos, Corinth, and Athens along with some of the smaller poleis joined together to fight Sparta in the Corinthian War. The war ended in a stalemate, but now the Persians were afraid of the growth of Athenian naval power.

In this lecture, Professor Kagan describes the aftermath of the Peloponnesian War and how the Spartans began to dominate other Greek poleis, instead of liberating them. The Spartan general Lysander at this point not only grows in influence and power, but also follows an aggressive plan to establish pro-Spartan, oligarchical governments. However, according to Professor Kagan, this fact angered many cities. Therefore, Thrasybulus, along with the help of other poleis, resisted Spartan rule.

In this lecture, Professor Kagan examines Pericles as a general. First, he describes Pericles' strategy of war and then he evaluates this strategy. According to Professor Kagan, Pericles' strategy was characterized by being both defensive and rational. It was defensive, because the Athenians did not engage the Spartans in a traditional hoplite battle, and it was rational, because Pericles assumed that the Spartans would cease fighting when they realized that the Athenians did not have to fight a land battle, since they had a walled city and a navy.

In this lecture, Professor Kagan focuses on the causes of the Peloponnesian War and the possible motivations for Thucydides' book, The History of the Peloponnesian War. Concerning the first point, Professor Kagan parts ways with Thucydides and argues that the war was not inevitable and that the Athenians under Pericles followed a policy of deterrence, which was aimed at peace. Similarly, he points out that there were a number of Spartans who did not want war as well. Therefore, according to this line of reasoning, war broke out due to a number of factors that were avoidable.

In this lecture, Professor Kagan describes the aftermath of the Thirty Years Peace. He argues that the Peace had the potential to keep peace between Athens and Sparta due to the arbitration clause. In addition, he argues that during this time, Athens sends various diplomatic messages to the wider Greek world stating their intentions for peace, such as the Panhellenic venture to establish Thurii. However, this peace is seriously challenged when Corinth and Corcyra come into conflict over Epidamnus.

In this lecture, Professor Kagan describes the events that lead up the Peloponnesian War. He argues that the rise of Athenian power and the concomitant challenge to Spartan dominance pointed to potential conflict. However, Professor Kagan also points out that there were many people who did not want war and that therefore war was not inevitable. The Thirty Years Peace was negotiated, and Professor Kagan finally argues that its clause for arbitration was the key clause that could have prevented war.

In this lecture, Professor Kagan continues to discuss the constitution of Athens. In particular, he explores the judicial workings of Athens. He describes in detail the effort of the Athenians to create a system of justice that would not only minimize tampering, in order to insure justice, but also maximize citizen participation. After this discussion, Professor Kagan comments on the role of women in Athens by looking at two types of sources. The picture that emerges is considerably complex and left without resolution. Finally, he comments on the role of slaves.

In this lecture, Professor Kagan describes the mechanics of the Delian League and its transformation into the Athenian empire. This transformation caused Athens to rival Sparta as an equal in power and prestige. He also argues that this process took place rather smoothly due to the good relations between Sparta and Athens. Professor Kagan argues that Cimon the Athenian generally played an important part in this development. Finally, Professor Kagan begins to describe the workings of Athenian democracy by comparing it with modern American democracy.
