The purpose of this study is to determine what motivated the noble officers of the Swedish military to participate in Gustav III:s 1772 Revolution. This investigation will be utilizing material written by participating noble officers between 1771 - 1773, originating from Gustavianska or Sprengtportenska samlingen, or from the biographies of Johan Christopher Toll and Jakob Magnus Sprengtporten. In order to fulfill the stated purpose of this investigation, three questions, one primary and two secondary, are formulated and answered in separate chapters. In addition, the investigation will be applying a qualitative text analytical method along with an deductive theoretical approach. This method, thanks to its hermeneutic utility, allows a comprehensive analysis of the motives stated in the material, and how the findings reflect on the military’s societal and political culture. The chosen theoretical framework which is applied deductively in the analysis, is Samuel Finers ‘military intervention’ theory. More specifically concepts from the section that covers military officers' motivations for intervening in politics. The final conclusions made in this investigation is that the officers were primarily motivated to join the coup to pursue the ‘national interest’. The noble officers had a longstanding hatred for the country’s political system, based on the conception that it was unable to adequately protect what they viewed as the nation's interests. The officers, who viewed themselves as the fatherlands protectors, joined the revolt in order to install a political system that they felt could protect the nation's continued existence. The officers were also motivated on the basis of ‘ideology’, as the conspiracy provided a opportunity to enforce Royalist political doctrine. Lastly, a further motive was the pursuit of ‘sectional interests’. The protection of ‘group interests’, in the form of protecting the nobility's political and financial privileges, as well as ‘individual interests’, where financial rewards and promotions were requested in exchange for allegiance, were also present.
