iTunes description: "Journalist and broadcaster Dan Carlin takes his 'Martian,' unorthodox way of thinking and applies it to the past. Was Alexander the Great as bad a person as Adolf Hitler? What would Apaches with modern weapons be like? Will our modern civilization ever fall like civilizations from past eras? This isn't academic history (and Carlin isn't a historian) but the podcast's unique blend of high drama, masterful narration and Twilight Zone-style twists has entertained millions of listeners."

Why it's on the list: Humans have been around for thousands of years, yet we rarely live past age 100. This makes it easy to repeat the mistakes of the past. Carlin shines his spotlight on historical events that we think we know about to show parallels with our own time, helping us to make more-informed decisions in the present.
