Sir Francis Drake, vice admiral was an English sea captain, privateer, navigator, slaver, and politician of the Elizabethan era. Drake carried out the second circumnavigation of the world in a single expedition, from 1577 to 1580, and was the first to complete the voyage as captain while leading the expedition throughout the entire circumnavigation. With his incursion into the Pacific he inaugurated an era of privateering and piracy in the western coast of the Americasan area that had previously been free of piracy.
