Fierce, a podcast from iHeartRadio and Tribeca Studios, tells the incredible stories of women who history has undervalued. In this episode, you’ll hear about Cheng I Sao, the most successful pirate of all time. She innovated the piracy business model, established strict rules about the treatment of women on her ships, successfully evaded the Chinese government, and, unlike pretty much every other pirate, retired. Listen to the rest of Fierce on the iHeart app or wherever you get your podcasts.
