This thesis is a study of disputes and conflicts between officers and men in the Royal Navy between 1793 and 1814. The first part is a general introduction to shipboard life and work, discipline, resistance and protest, and to the sailors' culture and politics. The second part is a detailed study of the mutinies on the Culloden in 1794 and the Defiance in 1795, paying particular attention to the organization of the sailors, the strategy of the officers and the function and working of court martials. The third part is a more general history of the sailors' protests and mutinies between 1796 and 1814. These mutinies and protests are situated with regard to the changing balance of forces between officers and men in the Navy as a whole during these years. The thesis is largely based on the verbatim transcipts of court martials in the Royal Navy that are now part of the Admiratly Records at the Public Record Office. It is intended as a contribution to the social history of the Royal Navy and the labour history of the period.
