The reason we study ancient history is for the insights it offers about the influence of character on human history. This series reduces the history of the rise and decline of the Roman Empire as it gathered, applied, and misused its power and wealth.
The major figures are Pompei (intrigue), Crassus (greed), and Caesar (ambition) who compete amid the chaos caused by individual ambition (financial, military, & political), entitlement, greed, and intrigue. Secondary characters are the Senate, Brutus, and Cleopatra who are acting blindly. It's an amazing distillation that anyone who lives in a democracy ought to view -- if they want to preserve it.
