Whilst the academic discipline analysing violence against civilians from a strategic perspective has seen significant growth over the last decades, a key issue has been neglected: the goals of the perpetrating actors. This thesis aims to narrow this research gap through answering the question: How do the conflict aims of rebel groups impact levels of violence against civilians? To do so, a theoretical framework is built, based on a categorisation of rebel conflict aims through combining a multitude of academic fields, which is then analysed through a large-N quantitative method. This study analyses an extensive 30-year world-wide dataset on the aims of rebel groups and rebel violence against civilians, and finds that different aims have significant effects on both civilian casualties and mass violence. Whilst some results support the hypothesised theories, others are indicative of contradictory relationships, further indicating the necessity of continued and expanded research into the conflict aims of rebel groups.
