"""In this lucid and engaging survey, two of the world’s leading experts on the history of freemasonry explain how it shaped modern social and political cultures. The history of freemasonry can be bewildering, but Margaret Jacob and Maru Vázquez provide an authoritative and accessible overview which deftly disentangles the many different threads in the masonic story. This will be the definitive introduction to the history of freemasonry for many years to come."" —Andrew Prescott, University of Glasgow"
