The skull and crossbones flag at the top of a pirate ship is called a Jolly Roger.Although the origin of the name “Jolly Roger” has been lost, one theory stems from the use of red flags. Centuries ago, a red flag was commonly used during naval warfare to signal that no mercy would be given, and anyone captured would be killed immediately. Called a Joli Rogue (“pretty red”) by the French, theorists claim this was then translated into English as Jolly Roger. Another theory suggests Jolly Roger derived from “Old Roger”, a term for the Devil. Oh these pirates, they’re so mysterious!
