The republic they started was an amazing beast where there were no servants, everyone was equal no matter what their skin colour and leaders were chosen by a vote. Compared to the societies these pirates had escaped from this must have seemed like paradise.
Colin Woodard has written an interesting and informative account of this period called The Republic of Pirates. Woodard has done a fantastic amount of research and it shows in the authority he brings to his subject.
Anyone interested in pirates or this period of history will enjoy this book.
