The History of Alexander the Great

During the Peloponnesian War, democracy was temporarily abolished at Athens. The city also experienced a plague which killed many of its citizens. Meanwhile, the Spartans built up their own navy and secured several important victories against Athens. But Spartan control was tenuous, and for the next few decades internal quarrels continued. In 338 BC, Philip invaded, and the Greek alliance fell to the Macedonians. Now Macedonian military power was combined with Athenian naval power and the Spartan army.
