Born out of bloodshed, sustained by sectarianism and shrouded in secrecy, the Orange Order is one of the most abiding and controversial religion-based organisations in Europe, if not the world. A Catholic cannot join: its doors are open only to those who profess Protestantism.

BBC journalist Mervyn Jess, who has written extensively on Orange issues, strips away the mystery and myths of the Order and traces its origins and defining moments spanning three turbulent centuries. This book is essential reading for anyone interested in finding out what "the Orange" is all about.
