For books about other ages of piracy - these are some good ones that I've read: - Pirate Utopias (Hakim Bey) - Corsairs of the 1600s, particularly in Sale (Morocco) and Algiers, with some information on Irish pirates of the same time - Pirate Enlightenment (David Graeber) - the "Pirate Kingdoms" of Madagascar and their relationships to the Malagasy - Rubicon (Tom Holland) - a history of the Roman Republic which also covers their death-struggle with ancient pirates
