Mutiny is often associated with the occasional mis-leadership of the masses by politically inspired hotheads or a spontaneous and unusually romantic gesture of defiance against a uniquely overbearing military superior. In reality it is seldom either, and usually it has far more mundane roots, not in the absolute poverty of the subordinates but in the relative poverty of the relationships between leaders and led in a military situation. Using contemporary leadership theory to cast a critical light on an array of mutinies across time and space, this book suggests we consider mutiny as a permanent possibility that is further encouraged or discouraged by particular contexts. What turns discontent into mutiny, however, lies in the leadership skills of a small number of leaders, and what transforms that into a constructive dialogue or a catastrophic disaster depends on how the leaders of both sides mobilize their supporters and their networks. From mutinies in ancient Roman and Greek armies through those that were generated by uncaring European monarchs and those that toppled the German and Russian states—and those that forced governments to face their own disastrous policies and changed them forever—this book covers an array of cases across land, sea, and air that still pose a threat to military establishments today.
