Description
A religious war or a war of religion, sometimes also known as a holy war, is a war and conflict which is primarily caused or justified by differences in religion and beliefs. In the modern period, there are frequent debates over the extent to which religious, economic, ethnic or other aspects of a conflict are predominant in a given war. The degree to which a war may be considered religious depends on many underlying questions, such as the definition of religion, the definition of 'war', and the applicability of religion to war as opposed to other possible factors.
