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. The battle, though close, was won by Philip and his Macedonian forces. Finally, Professor Kagan evaluates the actions of Demosthenes and concludes that his actions should be judged as a noble endeavor of one who loved freedom.
