Bartholomew Roberts (17 May 1682 – 10 February 1722), born John Roberts, was a Welsh pirate who was, measured by vessels captured, the most successful pirate of the Golden Age of Piracy. During his piratical career, he took over 470 prize ships. Roberts raided ships off the Americas and the West African coast between 1719 and 1722; he is also noted for creating his own pirate code, and adopting an early variant of the Skull and Crossbones flag.
