The connection between religion and conflict is widely known, but the literature lacks in the understanding on how religion can be used in conflicts. This study aims to investigate how religion was used by paramilitary organizations in the North Ireland conflict. With the theory on how religion can overcome collective action problems, four central themes regarding how religion can benefit social movements was used to examine these organizations. The organization was analysed using journalistic sources mainly based on interviews with terrorists from these organizations. Using these four themes the similarities and differences between these organizations could be analysed and how religion was used could be better understood. The main result was that none of the studied organizations used religion to a big extent, but that the protestant side had a bigger use of it than the catholic one. With this in concern, the study was critically analysed, and further research was purposed.

The purpose of this thesis is to understand the way in which religion and politics played a role in the formulation of a cyclical ethos of conflict, focusing in the last and most important civil war of nineteenth-century Colombia: The War of the Thousand Days (1899-1902). A historiographical review was used to understand the interactions between these two structures, and it pointed at a main problem centered in the political use of religion, as well as the transformation of political debate into a matter of political faith. In conclusion, the War of the Thousand days strengthened narratives of vengeance, worsened the situation of the country, and solidified an ethos of conflict in which the State used the Church to legitimize itself against the threats to the status quo of systemic inequality.
