Mike Duncan is an American political history podcaster and author. A self-described "complete history geek" grew from an interest in ancient civilizations as a child, with a particular affinity for Roman history. After not finding any Roman history podcasts in 2007, Duncan began The History of Rome. The podcast concluded in 2012. A year later he began Revolutions. Each season of the podcast focuses on one revolution. In 2017, Duncan wrote The Storm Before the Storm, which was well reviewed and appeared on The New York Times Best Seller List. His most recent work, Hero of Two Worlds: The Marquis de Lafayette in the Age of Revolution, received similar praise, earning its own spot on the New York Times Best Seller's.
