PIRATES AND THEIR TREASURE IN NEW ENGLAND AND ON CAPE COD. Who were they and why were they here? The Golden Age on Cape Cod in New England was between the years 1690 and 1730 and includes two eras: First is described as the "Pirate Round" the period of the long-distance voyages from the Americas (primarily Providence, RI) to rob Muslim and East India Company targets in the Indian Ocean and Red Sea. This era was followed by the post War of Spanish Succession period and the establishment of a Pirate Republic at New Providence and the Pirate's "Flying "Gang." Pirates have sequestered treasure at many New England locations and the largest Pirate treasure ever found, 4.5 tons of gold, silver and jewels, was found close to shore on Cape Cod.
