Barbary pirates
According to Robert Davis as many as 1.25 million Europeans were captured by Barbary pirates and sold as slaves in North Africa and the Ottoman Empire between the 16th and 19th centuries. These slaves were captured mainly from seaside villages in Italy, Spain and Portugal, and from farther places like France, England, the Netherlands, Ireland and even Iceland and North America. The Barbary pirates were also able to successfully defeat and capture many European ships, largely due to advances in sailing technology by the Barbary states. The earliest naval trawler, xebec and windward ships were employed by the Barbary pirates from the 16th century.
