To understand Athenian democracy, we first must understand Athens as a polis, or city-state, within the broader context of ancient Greece. Review the territory of Attica and get the lay of the land for Athenian government in the 6th and 7th centuries BC. Then, witness the great crisis that led to Solon's reforms and set Athenian democracy on its course.

Presidential crises and abuses of power aren't just features of modern times. Early executive scandals have had significant long-term effects that resonate down the corridors of time. Learn how we're still dealing with the fallout of famous investigations into abuses of presidential power, including Ulysses S. Grant's Whiskey Ring and Warren G. Harding's Teapot Dome scandal.

There are obvious correlations and differences between Athenian democracy and democracy today; and, now it's time to draw conclusions based on the comparison. In this final lecture, consider what the Athenians might have made of our democracy today and what democracy really means in the modern world, and whether it is as secure as we sometimes assume.

The most significant confrontation between a president and a president's investigators happens not in a court of law but in the court of public opinion. Often, the "storyline" is the deciding factor in how an investigation will be seen by future historians. Examine four different tactics used by President Bill Clinton and his team that helped them achieve a public relations victory.

Conclude this lecture series with a study of the "nuclear option" in presidential investigations: impeachment. Learn why impeachment is inevitably as much a political event as a legal one - and why, when a presidency is on the line, public opinion is at least as powerful a determinant of the outcome as the laws that are on the books.

The expedition to Sicily is one of the biggest military blunders in ancient history. Much like the ill-advised American war in Vietnam, the Sicilian expedition was an avoidable disaster.
