Bartholomew Roberts, Welsh pirate (died 1722)

Bartholomew Roberts, 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 400 prize ships, although most were mere fishing boats. 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.
