Vad motiverar militären att genomföra en kupp och vilka faktorer påverkar kuppförsökens utfall? : En jämförande studie av militärkupper i Chile 1973 samt Turkiet 1997 och 2016

This thesis examines the underlying motivations behind military interventions and the factors influencing the success or failure of coups. By analyzing four cases- Chile (June and september 1973) and Turkey (1997 and 2016) - the study applies Samuel P. Huntington´s and Samuel E. Finer´s theories on civil-military relations to assess how ideological, institutional, and external conditions shape military behavior. Employing a theory-testing, comparative case study design, and unsing methods such as process tracing and the Most Similar Systems Design (MSSD), the research identifies key variabels associated with coup outcomes. The analysis reveals that the military interventions are often driven by a combination of ideological threats to the existing social order, institutional concerns regarding the military´s role and autonomy, and perceived threats to national security and regime legitimacy. Successful coups tend to occur when the military is unified and the civilian leadership lacks legitimacy or capacity to resist. In contrast, failures are commonly linked to internal divisions within the armed forces and resilient civilian institutions. This study contributes to a deeper theoretical and empirical understanding of the dynamics behind military coups and the variation in thier outcomes.
