This episode originally aired in May of 2015.
From the original show notes: In this episode of The History Files, Gordon cites three examples from history that illustrate national conditions which usually lead to revolution, sometimes even several waves of revolution. Bonus: stay tuned after the sign-off to hear Nancy and Gordon ramble on about Iran, pop-culture wars, and that inexplicable statue of Lenin in Fremont (a neighborhood on the ship canal north of Seattle).
