Particularly during the 1600’s, maritime technology began innovation. Trading traffic increased, which for pirates meant more ships to ransack and give rise to their piracy. By the 1690’s, pirates began a route they named the “Pirate Round.” They would sail from the Indian to the Red Sea, searching for trade ships deploying from India. 1718 was the beginning of the end for the “Golden Age of Piracy.” Two years later, in 1720, the English captured famous pirate Jack Rackham and his two female shipmates. In 1722, the wealthiest pirate known had died. His name was Bartholomew Roberts. By 1730, this era had ended.
