This book is the first to compare the shared cultural tenets of ancient warbands and outlaw biker gangs. It argues that the values of hyper-masculinity can be traced from the former into the contemporary environment of the latter: codes of honour, loyalty and bravery have prioritised small groups of males over women and other men, creating a history of hyper-masculinity that shows little sign of stopping. Indeed, Outlaw Bikers and Ancient Warbands: Hyper-Masculinity and Cultural Continuity argues that such hyper-masculine culture can be found in many male groups such as the police, military and sports, and that if we want to understand hyper-masculinity and face it as a society then we need to recognize that outlaw bikers are a reflection of behavior that has a very long tradition. This pioneering work explores these issues from ancient times and into the future.
